Pulau Seri Buat is a part of the infamous Marine Park of Tioman, off Pahang waters, yet little is known about its coral reef community. Therefore, a study was conducted in 2016 to investigate the community structure of coral reefs in Pulau Seri Buat. The coral survey was conducted using a Point Intercept Transect method at three sites. The result showed that the average live coral cover of Pulau Seri Buat was 52.6%. In total, 30 genera of scleractinian corals from 11 family and 2 scleractinian incertae sedis have been recorded, with Acropora and Porites were the most abundant genera. No recently killed corals was found at any site. The coral diversity was highest at Site 1 (ST1) with Shannon Diversity Index (Hˈ) and Evenness index (HE) was 1.43 and 0.45 respectively. These results suggested that the coral reefs of the island were still in good condition. This study could provide an important assessment of the coral condition of Pulau Seri Buat.

A survey to determine the ecological character focusing on the condition and vegetation structure of the dambo wetland eco-system in the upper sub-catchment of the Chongwe River, central Zambia was carried out focusing on five dambos and associated forests in Kanakantapa area. Line intercept method was used to evaluate herbaceous cover which also included shrubs and forbs, while woody plants were assessed using Point Centred Quadrat (PCQ) method and species importance values. Results of the study showed that dambos were largely dominated by Loudentia simplex (Nees) Hubbard (30.5%), Digitaria milanjiana (Rendle) Stapf (21.7%), Setaria ciliolata (26%) and Setaria anceps Stapf ex Massey (20.0%). Important woody plant species were Julbernardia globiflora (97.56 IV), Monotes katangensis (66.91 IV), Julbernardia panniculata Tropin (57.33) Acacia sieberana DC. (52.39 IV), Pseudolachnostylis maprouneifolia (40.72IV), Brachystegia boehmii (35.99 IV) Albizia antunesiana (33.43 IV). All dambos studied showed shrub encroachment with relatively high number of shrub species in Kanakantapa and Mwiinde dambos ecosystems. Highest shrub canopy cover was observed in Kanakantapa dambo. It was concluded that dambos were largely at high risk of degradation due to mainly siltation influenced by deforestation, overgrazing and shrub encroachment. Further research is required to guide sustainable land use and future plans of possible catchment management as well as determining hydrological implication and possible ways of conservation of dambos.

Correlating The Development of Sheath Blight Disease of Rice With Changing Climatic Factors
Somshetty Ravali,
Bimla Rai,
Prem Kumar Jha
Rice is an important staple food crop for more than 60% of the world population and is subject to various biotic and abiotic stresses which cause yield losses up to 20-30%. Sheath blight of rice caused by Rhizoctonia solani Kuhn is a potentially devastating fungal disease under suitable conditions. Studies on correlation between the development of sheath blight of rice and changing climatic factors was carried out by taking six weather parameters as independent variables and cumulative and periodical increment in disease severity as dependent variables. Disease severity significantly correlated with maximum temperature, minimum temperature, evening relative humidity, and evaporation. It revealed that high temperatures (30-34 0C) and high relative humidity (above 90%) were responsible for the establishment of sheath blight disease in rice.

The climbing beans varieties are more productive than dwarf varieties. However, the expansion of their culture is limited by the availability of stakes. In addition stakes must meet certain criteria (eg length) for good plant growth. It is therefore important to research optimal staking methods for good production of climbing beans. It is for this purpose that a test was conducted in the agro pastoral area of Mushweshwe, in the Bushumba area, Kabare territory. The experimental set-up was complete random block with 5 repetitions and 5 types of staking: the stake of the tripod, the outside T stakes + string + spike, the single stake of 3 m, the crossed stakes and the single stake of 1 m considered as control treatment. Single stake of 3 m has the same yield 4 to 5 t/ha as outside T stakes + string + spike. The following staking: crossed stakes and single stake of 3 m are so vigorous than rope or outside T stakes + string + spike, stake of the tripod and single stake of 1 m. Crossed stake plants are taller or giants and also a higher number of seeds per pod than single stake of 3 m, rope, stake of the tripod and single stake of 1m. The leaf area of climbing bean is the same for all applied stake systems. Single stake of 3 m (P3) has the same yield as outside T stakes + string + spike which has a high performance (4-5 t / ha) than stake of the tripod, crossed stake and, single stake of 1m .For a better future of our households, and also for a good economy and development, we recommend to the practice of climbing beans by sowing in rows and using the single stake of 3 m and the outside T stakes + string + spike or a rope. Let climbing bean farmers know that the ideal long stake is 3 m. The production increases steadily with the length of stakes up to this level and remains unchanged beyond this height.

Impact of Salinity Stress During Germination Stage on Chickpea (Cicer arietinum L)
The salinity of irrigation water is a serious problem facing crop plants in the Mediterranean region, where plants are exposed to high temperatures and severe shortage of water in the dry season. So, this study was carried out in order to test the effects of five different salinity levels of sodium chloride (0.0, 50, 100, 150, 200 and 300 mM) on seed germination and early seedling growth of Chickpea (Cicer arietinum L.). Fifty homogenous and cleaned seeds were germinated in Petri dishes inthree replicates. The salt stress decreased seed germination, the response of Chickpea (Cicer arietinum L.) to salt stress and water stress was evaluated at the germination stage. The severe reduction in germination percentage and particularly germination speed with prolonged lag period by moderate salinity level at 100 mM NaCl, suggests that Chickpea (Cicer arietinum L.) is a salt-sensitive species during germination. Salinity reduced germination uniformity and germination synchrony and might delay start of germination but accelerates its termination with a consequent shortening of the time spread of germination. The recovery percentage was lower but speed of recovery was higher compared with the corresponding parameters of the control seeds. Recovery percentage was slightly improved with increasing in the concentration of NaCl .

Comparison of Methods to Improve the Capture of Marmosa Mexicana in a Neotropical Area
Flores-Peredo Rafael,
María del Coral Rosas-Ronzón,

Marmosa mexicana, a small semi-arboreal marsupial with a Central-American distribution, from the southern portion of the Mexican state of Tamaulipas to western Panama, remains one of the least-represented species in small-mammals inventories, and one of the least known. Capture is usually done with traps placed on the ground, baited with peanut butter and oats. In the Neotropical realm, the vertical placement of traps on trees with different baits has proved to be more efficient in the capture of marsupials. In this study, we comparatively evaluated the effectiveness of different types of bait and trap placement (ground versus tree) in the capture of M. mexicana in a peri-urban park in Xalapa, Veracruz, Mexico. From January to July 2017, six linear transects 200 m long were randomly established for the placement of 40 Sherman® traps every 5 m, alternating ground and tree locations (at a height of 4 m). Traps were baited with four items: banana with meat and crickets, apple with blueberries, papaya with sweet corn, and peanut butter with oats. A factorial ANOVA was used to evaluate the effect of the type of bait and site on the number of catches. In a sampling effort of 5,040 trap nights, 75 catches were recorded, which represents a success rate of 1.48%. We found that only the site of trap placement was significant. Our results suggest that, with any of the baits, the placement of traps on trees can make the capture of M. mexicana more successful.

Mineral nutrient uptake of maize and banana in an intercrop with agroforestry tree species in Vihiga County, Kenya
Simiyu Dennis Wamalwa*,
Sikuku Anyango Phoebe,
Musyimi Mutisya David
Western Kenya faces high population pressure and this has increased demand for food. Smallholder farmers in the region have been forced to practice poor farming practices such as continuous cultivation and clearing of forests to put more land to crop production. This has resulted in severe land degradation, climate change and reduced farm productivity. Agroforestry trees have been reported to improve soil fertility through nitrogen fixation coupled with leaves and twig decomposition. However, this has not been ascertained in maize-banana agroforestry systems in Vihiga County. Understanding the effects of intercropping of maize and banana with Sesbania sesban, Calliandra calothyrsus and Leucaena diversifolia agroforestry trees on nutrient uptake may be a remedy to the challenges. Therefore there is need to fully understand the effects of intercropping selected agroforestry trees with maize and banana on nutrient uptake of maize and banana. The objective of the study was to determine the effect of intercropping agroforestry tree species on maize and banana tissue N, P, K, Mg, Ca uptake and partitioning. The study was conducted at Maseno university farm located in Vihiga County. The Williams varieties of banana of the same age were obtained from KALRO-Thika., Seeds of selected agroforestry trees were purchased from KEFRI – Muguga, planted in a seedbed and the seedlings raised in nurseries. Hybrid maize seed, H513 was purchased from an agrovet. Banana holes were dug 2x2 feet, 20 Kg of decomposed cow dung manure + 20 Kg of top soil + 200g of NPK fertilizer added in each banana hole and banana planted. Randomized complete block design (RCBD) with 3 replications were used with seven treatment levels of i.e. maize, banana, maize + banana + Calliandra, maize + banana + leucaena, maize + banana + sesbania, maize + banana, and fertilized maize. Maize were planted at 0.75 m inter row by 0.3 m spacing. Five maize plants per treatment and per replication were sampled randomly from the eight middle rows at harvest and partitioned in to leaves, shoots, roots, cobs and maize grains. Two banana plants were sampled and its leaves taken for mineral tissue analysis. The maize roots were washed in water to remove soil. The samples were oven dried to a constant weight at 72 0C. The samples were then ground into powder for determination of nutrient analysis. Procedures by Motsara and Roy (2008) was used to determine the nitrogen, phosphorus, potassium, calcium and magnesium mineral nutrient in various plant tissues. Data was subjected to Analysis of Variance using Genstat statistical package Version 15.2. Maize and bananas that were intercropped with trees recorded highest nutrient uptake and partitioning. Sesbania sesban recorded higher nutrient uptake as compared treatments without tree intercrops. These findings can be used to advice smallholder farmers of Vihiga County on the best intercropping system to adopt for maximum maize and banana production.

Nawal Shelig
Background: L. bryoniae is a Palearctic species which probably originates from southern Europe, where it occurs commonly outdoors but has now spread to many parts of central and northern Europe and is also reported in North Africa (Morocco and Egypt), as well as in several countries in Asia. L. bryoniae is polyphagous and as such can feed indiscriminately on plants from a number of different orders, including many vegetables and ornamental species. Objectives: The present study aimed to investigate the population abundance of the tomato leafminer L. bryoniae on three selected host plants. On the other hand, host plant preference by L. bryoniae was investigated. Methods: 100 infected leaves were collected from each host plant. Samples were kept in plastic bags and transferred to be examined in the laboratory. Number of living L. bryoniae larvae were counted and recorded. Results: L. bryoniae larvae recorded low abundance on Kidney bean in early May, then the population increased recording three peaks of abundance recording (127, 158 and 179 individuals/100infested leaves) occurred in 22th of May, the 19th of June, 24th of July. On tomatoes L. bryoniae recorded low numbers in early May, then the population increased recording three peaks of abundance (109, 121 and 104 individuals/100infested leaves) occurred in 22th of May, the 3rd of July, 31th of July. On bell pepper L. bryoniae recorded low numbers in early May, then the population increased recording three peaks of abundance (87, 103 and 88 individuals/100infested leaves) occurred on 29th of May, the 10th of July and the 7th of August. Conclusions: L. bryoniae larvae recorded low numbers in the beginning of the growing season in early May on the three summer host plants, then the population increased recording 3-4 peaks of abundance.

The study was conducted with the aim of callus induction and indirect and direct shoot formation from culturing the axillary buds of the tulip cv. Arma on the MS medium equipped with 1.0 mg L-1 NAA and 0.5, 1.0, 1.5, 2.0 or 2.5 mg L-1 BA. The results showed that the callus tissue did not grow when the axillary buds were cultured on the MS medium which supplied with 1.0 mg L-1 NAA and 0.5, 1.0 or 1.5 mg L-1 BA after eight weeks from culture. However, the axillary buds cultured on the MS medium which supplied with 1.0 mg L-1 NAA and 2.0 or 2.5 mg L-1 BA which led to callus induction after eight weeks from culture. The treatment of 1.0 mg L-1 NAA and 2.5 mg L-1 BA was a significant increase in the percentage of callus induction and indirect shoot formation and the number of shoots. The results showed that the callus cultured on the MS medium that supplied with 1.0 mg L-1 NAA and 2.0 or 2.5 mg L-1 BA led to the formation of the adventitious shoots formation eight weeks after culturing. While, the axillary buds cultured on the MS medium which supplied with 1.0 mg L-1 NAA and 0.5, 1.0, or 1.5 mg L-1 BA led to the direct adventitious shoot formation eight weeks after culturing. The MS medium that supplied with 1.0 mg L-1 NAA and 1.5 mg L-1 BA was a significant increase in the percentage of response to direct adventitious shoot formation and the number of shoots.

The present study was conducted to know the present status of turkey production, existing system of rearing, feeding and management practices of turkey production in Patuakhali district of Bangladesh during March 2020 to September 2020. A total of 10 turkey raisers were surveyed from different Upazilla of Patuakhali region. The data were collected about status of farmers, size of the farm, rearing system, feed intake, breeding policy, and management practices and production performances. Among 10 turkey keepers 57% were women and their occupation were housewife remaining 43% were men and their occupation were business and farming. No vaccination schedule was maintained by most of farmers. Among them only 43% farmers vaccinated against only RDV, Fowl Pox, Coryza diseases. Hosing system were mainly traditional housing system which are practiced by most of the rural farmers. They have very little idea about breed or variety, management procedure and prevention of diseases. We know in Bangladesh there is no specific feeding standard of turkey as like as broiler and layer chicken. Most of the farmers fed the birds using broiler and layer feed along supplemented with kitchen waste, water hyacinth different grasses etc. For this reason more research needed to develop feeding standard of turkey, improvement of production, and their suitability in rearing all over the area of Bangladesh.

The quantitative effect of different growth parameters like temperature, pH and dextrose to produce extracellular polysaccharide from the mushroom Agaricus heterocystis (AGH) was studied by using Response Surface Methodology (RSM) three factor Box-Behnken design. The experimental data obtained from this study was exactly fitted with a second-order polynomial equation using multiple regression analysis. The surface contour plots of the model predicted that temperature of 30.9°C, pH 4.9±0.2 and dextrose concentration of 1.99 g/100 ml were the optimum growth condition required for the maximum production of extracellular polysaccharide. The predicted yield of extracellular polysaccharide reached around 2469 µg/ml which was relatively significant with the validation experiment. The extracted polysaccharide was purified partially for NMR studies confirmed the presence of glucan-protein complex. The partially purified polysaccharide under ex vivo condition showed anti-angiogenic property needs further study to screen for antitumor and antimetastatic properties.

The peculiarities in the development and changes in the subtropical agricultural landscapes (in western Georgia)
Elene Salukvazde,
Tamila Chaladze
The article points out natural and anthropogenic factors contributing to the formation, development and alteration of agricultural landscapes in western Georgia, specifically, in the Colkheti coastal plain and the adjacent hilly foothill zone, where subtropical agriculture used to be heavily developed (tea and citrus plantations, etc.). The former state-owned tea farm zone in the borough of Laituri, Ozurgeti municipality, Guria was selected as the study location. GIS technologies were applied to digitalize the 1960 landscape map of the zone and create its new version (1:50 000) as of 2017 based on the topographical map of 1960 (1:50 000), satellite images and field observations (2010-2017).
The analysis of the Laituri 1960 and 2017 landscape showed that 66% of tea plantations have been amortized and degraded: they have gone wild and are overtaken by weeds. Due to high costs involved, only 10% of the area was cleared to cultivate hazel nuts, blue huckleberry and persimmon. 24% of tea plantations survive to varying degrees and are currently harvested.

Beans are an important crop in the Democratic Republic of the Congo. It is consumed in three forms green beans, fresh seeds and dry seeds sometimes as vegetables. The aim of this study was to assess the main production constraints of common bean in Birava Kabare North area at the South Kivu province and east of the Democratic Republic of Congo. A questionnaire consisting of structured, semi-structured and unstructured items was designed based on published literature on the subject as well as experiences of the authors in the field. The results of this study have shown that 36% of the farmers affirmed that the pests’ bean crop attack such as black aphids and 89.2% observed the diseases in their bean crops. The farmers practice plowing on mounds or ridges, while this plowing favors interventions on the soils that risk injuring the roots which leads to an increase in the frequency of diseases and a reduction in the cultivable area. According selected seeds, a large number of farmers (74.2%) used seeds found on the local market, this seed is of average to poor quality and often contaminated. Cultivable land per household is still insufficient because 60% of the population has an area of less than 0.5 hectares. Additional, a large number of farmers (29.2%) did not stake on climbing beans, while staking can double production. Indeed, the lack of financial means which prevent a large number of farmers from obtaining chemical fertilizers (61.7%) and the majority of small holders (95%) did not receive any technical training. In addition, as elsewhere, factors linked to the climate have a negative influence on yield, such that 99.1% of farmers mentioned the problem of the prolonged dry season which arises from year to year. We recommend accentuating extension efforts in the field of cultivation techniques, fertilization without forgetting the integration of agro-forestry tree and granting long-term agricultural loans with an interest rate that is bearable by farmers.

This study assessed the effects of smoking on proximate composition of some marine fishes: Ethmalosa fimbriata, Pseudotolithus enlongatus, Mugil cephalus and Lutjanus goreensis. The fishes were purchased from Creek Road Market in Port Harcourt. Four kilograms each of the fish species were used for the analysis in both the fresh and smoked processing using the improved NIOMR kiln. Each of the four fish species were replicated three times. The fish were prepared and placed in the kiln for smoking. The time and weights were recorded attained after smoking was recorded. The Fresh and Smoked fish samples were then analyzed for proximate composition such as moisture content, crude protein, crude fat and total ash using standard methods. Data obtained were subjected to analysis of variance. A decrease in moisture content was observed during smoking and constant weight was obtained within 10-20 hours. An inverse relationship was observed between the moisture and protein content in the smoked fish samples. The crude fat and ash contents in each of the species of the fish samples were significantly (P<0.05) higher in smoked fish samples than the fresh ones. In conclusion, the smoked fish samples recorded higher values for all the nutrients except for the moisture content which was higher in the fresh samples.

The study on the propagation of banana seedlings took place in Lwami in the Cirunga area, Kabare territory. The aim was to improve banana production in South Kivu in general. The rapid multiplication of bulbs in the macro propagator as the sampling method experimentation coupled with observations in the field. The multiplication rate in situ was 15.5 for dessert banana (FHIA 23 variety), 6.4 for plantain (FHIA 21 variety) and 5.3 cooking banana (FHIA 17) compared to the beer banana (CHIBULULA variety) which multiplication rate was 1. In the field cultivation, FHIA 21 and FHIA 23 have a large size and offspring than CHIBULULA and FHIA 17 but they are no difference into FHIA 21 and FHIA 23 according number of offspring and l size. Again, the number of banana leaves emitted and banana pseudostem heights of those varieties are the same in ex situ cultivation. The multiplication of banana seedlings is an asset in the middle of South Kivu to have the suckers quickly exempt from diseases. This work recommends the Agriculture Inspectorate to make the banana offspring available to farmers, allowing them to multiply this crop.

Bermuda grass is a warm-season, drought resistant, salt tolerant grass and has the ability to grow in a broad range of temperatures. While nitrogen fertilization is one the technologies for which optimization is being sought in order to increase foliar development, much is lost through various processes such as leaching, volatilization. Foliar fertilization allows the plants to obtain equally distributed and easily absorbable essential nutrients however the amount of N lost due to volatilization has not been quantified in previous studies. Hence, the study was designed to assess the quantity and rate of volatilization of nitrogen from foliar fertilizers applied on different cut-heights of Bermuda turf in golf courses. Volume of N gas escaped was analyzed using a gas analyzer SKY2000-M4 with respect to the time elapsed after application. Results showed a graphical relationship for the volatility of nitrogen and factorial 1.15823% could be taken into consideration to meet the optimum crop nitrogen requirement while doing foliar fertilization.

Enzymes Activities in the plasma of Clarias gariepinus and Heterobranchus longifilis Reared in Different Culture Systems
This study assessed the enzymes activities in the plasma of Clarias gariepinus and Heterobranchus longifilis reared in different culture systems. A total of two thousand eight hundred and eighty (2,880) fingerlings of two species consisting of 1440 Clariasgariepinus(mean length 5.42cm ± 0.67 and mean weight 3.34g± 0.33SD) and 1440 H.longifilis (mean length 5.43cm ± 0.88 and mean weight 3.35g± 0.31SD) were reared in four different aquaculture enclosures namely: earthen ponds, tarpaulin, concrete and plastic tanks of the same dimension (1.0 x 1.0 x1.2m3) for a period of 12 weeks. The results obtained, indicated that enzymes activities such as Acid Phosphatase (ACP); Alkaline Phosphatase (ALP); Aspartate Transsaminase (AST); Alanine Transaminase (ALT) and Lactate Dehydrogennase were significantly (P <0.05) elevated in the plasma of cultured fish, which was more pronounced in those reared in concrete and plastic tanks. Based on the results of this study, rearing of C. gariepinus and H. longifilis in tarpaulin tank is most effective and ideal method for fish production if the target is to attain fast growth and good health condition of the fish.

To Evaluate the Trigger Factors and Hormonal Abnormalittes in Adult Female Acne
Background: Women's acne, which can start in youth and last into age, is frequently linked to anxiety and sadness. Its etiopathogenesis is influenced by genetic and hormonal variables, and because of the clinical progression, maintenance therapy is necessary, typically for years. Recurrent acne, a third form of acne that has lately been proposed in addition to chronic and late acne and that first appears in adolescence, improves for an undetermined amount of time, and then reappears in maturity. [6] There aren't many papers on this since modern research seldom asks the patient if acne returned after an adolescent era, while querying the age of acne start.Materials and methods: Nonpregnant females with acne aged 25 years who had not been on hormone medication for the previous three months were the subjects of this prospective research conducted at the R V M Medical College's Department of Dermatology's Outpatient Clinic. A thorough history was obtained, and a proforma that had been authorized in advance was followed. A pre-designed proforma was used to examine patients with acne under the age of 25 in order to identify trigger factors and rate the severity of the acne using the Global Acne Grading System (GAGS). Total testosterone (TT), AMH, 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone sulfate (DHEAS), sex hormone binding globulin (SHBG), free androgen index (FAI), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), and prolactin were all measured as part of a thorough hormonal evaluation.Result: just 4.28% of acne patients were beyond the age of 40, while the majority of acne patients (58.57%) were between the ages of 21 and 30. 70 adult female acne patients were seen, and 61.42% of the women had late-onset acne, whereas 38.57% had chronic acne. Papules were the most prevalent lesion at the time of presentation (61.42%), followed by mixed lesions, which included pustules and nodules. The severity of the patient's acne was rated as mild (72.8%), moderate (25.71%), or severe (1.42%). According to the subjective assessment, 21.3% of women experienced a clear premenstrual flare. The objective evaluation found that nutrition had a role in the health of 23.33% of patients, with "oily" and dairy products being prevalent items, sugar products and cosmetics, fairness creams, foundations, facials, and change of life style, with lack of physical excessive, obesity. Fairness creams, foundations, and facials were among the cosmetics that were at fault. While sunscreens had the highest maximum frequency per month, "fairness creams" were found to have the highest mean duration.Conclusion:Diet, stress, and cosmetics may all contribute to adult female acne, and a specific hormonal environment is responsible for both hyperandrogenemia and elevated levels of adrenal androgen. We discovered that stress and sleep deprivation were both prevalent in a significant number of individuals with high levels of adrenal hormones, suggesting a shaky connection between stress and acne. We have also established that adult female acne patients had elevated AMH levels, and more research on this hormone in adult acne patients is needed.

Contemporary Challenges and Solutions for Equity and Social Inclusion in Community Forestry, Nepal: A Review
Parbat Raj Thani,
Prashid Kandel
Community forestry is considered one of the successful programs in terms of natural resource regulation and protection in Nepal. It was started with the focus on the forest conservation through peoples’ participation and also satisfying their basic forest product’s needs. Later on, its limitation of tasks expanded and started working also on many cross cutting issues including institutional sustainability, good governance, sustainable livelihood, community development, democratic civic engagement and equity aspects of forest management (e.g. distribution of costs and benefits, access to decision-making). This review paper was designed to contemplate constraints and challenges on the social inclusion and equity aspect of forest management in community forestry and find out solution collectively. Many related peer reviewed research articles and government documents were taken into account and the result analysis was done based on the existing literatures. The study showed that there is not satisfactory inclusion of women, poor, lower caste and other disadvantage groups in community forestry in terms of distribution of costs and benefits and access to decision-making as a result of weak implementation of gender equality and social inclusion policies, weak institutional structure and capacity, inadequate awareness, inadequacy of gender disaggregated data, insufficient inclusion of gender and social inclusion criteria in monitoring and evaluation or in budgeting programmes and so on. To cope with these issues, fully implementation of policy provisions; formulation of strategies based on national debate, past research and their implementation; continuation of empowerment, formal and informal education through different ways at local level to improve literacy and awareness about rights of women and excluded groups; putting some preconditions on development assistance; strengthening of local institution to tackle equity and social inclusion; provision of adequate fund and regular assessment of policy, implementation and the revision might be helpful.

Luh Putu Kirana Pratiwi
Agro-tourism is a means of increasing added value, opening jobs, expanding markets for agricultural products, and supporting efforts to increase income and farmers' welfare. Characteristics of agro-tourism is a resources-based industry, the direction of its development strategy must be based on a potential resource area approach while still based on the concept of comparative advantage. Plantation agro-tourism development should refer to a superior commodity approach. Production diversification has not yet developed and its by-products have not been utilized. This study aims to formulate a cocoa commodity agro-tourism development strategy. The research object was cocoa farmers in Melaya District, Jembrana Regency using the SWOT analysis method. The results showed that the cocoa commodity agro-tourism development strategy was in quadrant I or a strategy made using all strengths to take advantage of opportunities, namely aggressive strategies. Aggressive strategy based on internal strength factors and opportunity factors which are external factors with alternative strategies: increasing farmers' independence through coaching and counseling, developing partnerships in agro-tourism activities to add value-added production of cocoa commodities.

The Synergistic Interaction of Consumption of Staple Cassava-Diet and Nitrate/Nitrites-Containing water in Metabolism of Cyanide Toxicity in Albino Wistar Rats
O. S. Bakare,
O. Y. Adeniran,
S. M. Daniel
This research work investigated the synergistic interaction of consumption of low proteinous staple cassava diet and nitrate and nitrite-containing water with a view of assessing the chronic toxicity of cyanide toxicity to animals feeding on cassava diet and evaluating the level of nitrate in water sources consumed by students in the university community viz-a-viz studying the link between cyanide and nitrate metabolism amongst the people of Akoko environs of Ondo State, Nigeria. The metabolism of a low protein cassava diet and nitrate/nitrite-containing water was investigated in albino wistar rats fed on a low protein cassava diet. The cassava roots were harvested, peeled, washed and cut into smaller sizes to aid quick homogenization, blended with cold ortophosphoric acid until complete homogenate and the homogenate were centrifuged to obtain a clear supernatant. The assays and activity of total and free cyanide, determination of urinary thiocyanate contents, sodium thiocyanate assay, linamarin contents, determination of crude linamarase enzymes, reduction of nitrate to nitrite in water by cadmium column, hematological assay and serum enzyme assay were performed using standard methods. Fifty-five recently weaned albino Wistar rats were acclimatized and used for this research work. They were placed on commercial rat’s pellets and or on a formulated diet containing 80 % cassava and 20 % pellets. A dose of 100 µg/kg body weight of sodium nitrate (NaNO3) or a sodium nitrite (NaNO2) and free drinking water were administered throughout the duration of two month of the experiment. The animals were divided into five groups of five animals each; animals in group one were administered cassava diet and free nitrate water, group two received cassava diet and 100 µg/kg body weight nitrate water, group three animals received pellet and 100 µg/kg body weight nitrate water, group four animals received pellet and 100 µg/kg body weight nitrite water and group five animals received pellet and nitrate free water. The animals in group five served as the control. Urine samples were collected weekly and analyzed. At the end of the experiment, the animals were sacrificed, and blood samples were obtained by cardiac puncture for enzyme, hematological, and liver and kidney function tests. Results showed markedly increased urinary excretion of nitrate, nitrite, hydrogen cyanide, and thiocyanate ions in the test group compared to controls. Weight loss, reduced packed cell volume, white blood cell count, and hemoglobin concentration were observed in test rats. Elevated serum enzymes and hepatomegaly further indicated the toxic effects of cyanide and nitrates. Nitrate levels in water sources from towns in Akoko North East and South West of Ondo State, Nigeria, were also assessed. Borehole water, particularly in Akungba Akoko and its environs, showed the highest concentrations. The study concluded that cyanide toxicity is prevalent in this area due to consumption of cassava-rich diets combined with nitrate-contaminated water, possibly explaining the high incidence of related diseases.

A Review of Community Forestry Contributions to Livelihood Assets in Nepal and Contemporary Challenges
Parbat Raj Thani,
Prashid Kandel
This paper is designed to demonstrate contribution of community forestry management practice in Nepal for the improvement of livelihood assets and identify the overall ongoing challenges that are hindering the sustainable livelihood development. Many related peer reviewed research articles and government documents were taken into account and the result analysis was done through using sustainable livelihood framework of DFID, 2000. The results showed that successful implementation of community forestry has been able to bring many positive changes in overall livelihood assets (natural, social, physical, financial and human capitals) in comparison with the previous situation. However, many obstacles in sustainable livelihood development have also been observed at the same time. The observed shortcomings are lack of mainstreaming biodiversity and ecosystem services, poor PES strategy implementation, lack of linking forest to food security, lack of measuring the sustainable use of forests and other natural resources(natural capital), weak and inefficient governance, equity, cost and benefit sharing (social capital), lack of community forest based enterprise development(financial capital), lack of literacy in poor, ethnic and lower cast, women(human capital) which need to be curbed.

The Effect of Tilapia Excreta on the Growth of Jumbo Sweet Pepper Plants
Videsh Ganesh,
Gomathinayagam Subramanian
This research was carried out using fish excreta as a fertilizer treatment for sweet pepper plants. The fish excreta solution was obtained from a tank containing a specie of tilapia Oreochromis mossambicus. Sweet pepper plants (Capsicum annuum var. annuum (Grossum Group) ‘Jumbo Sweet F1’) were grown in three (3) different beds, while each bed was treated with a different fertilizer treatment; fish excreta, cow manure and N.P.K 6.25.25. The difference in vegetative growth, reproductive yield and effect of the fertilizers on the soil’s pH was observed and recorded. The differences in vegetative growth recorded for the plants treated with fish excreta compared to cow manure and N.P.K treatments were not statistically significant. The total weight of fruit harvested on plants treated with fish excreta was significantly higher than the weight of fruit yielded from the plants treated with N.P.K and cow manure. The soil pH of the cow manure and the fish excreta treatment stabilized at a range which was suitable for the sweet pepper plants between pH 5.5 and pH 7.5, whilst soil pH of the N.P.K treatment expressed a drastic decrease to a more acidic pH range below the tolerance level of the plants.

Growth and Yield Performance of “Sakurab” Scallion Green Onion (Allium Fistulusom L.) Under Different Rates of Chicken Dung and Sources of Soil Amendment
The growth and yield performance of “sakurab” scallion green onion (Allium fistulusom) was determined by the use of different rates of chicken dung (5 tons/ha, 10 tons/ha, 15 tons/ha) and soil amendments: rice hull, carbonized rice hull, rice hull ash and mushroom spent with the following objectives namely to: “Evaluate the plant height of scallion green onion. Determine the number of tillers. Identify the number of leaves of scallion green onion bulb. Measure the diameter size of scallion green onion. Determine the percent recovery of marketable of scallion green onion. Analyse the Percent of Return of Investment. The study employed a two factor experiment under Randomized Complete Block Design. The results showed significant differences among treatments in the different rates of chicken dung in the average plant height, initial weight (intact leaves) and final weight (detached leaves). Non-significant differences among treatments were noted in the number of leaves, number of tillers, diameter of bulb and percent recovery. In the interaction of different sources of soil amendments and chicken dung, A2B1 (Rice Hull + 5 tons/ha chicken dung) obtained the highest return of investment with 263.63% and also noted with the highest net income (Table 8). Thus, the different sources of soil amendments and rates of chicken dung greatly affect the growth and yield performance of scallion green onion. Hence, rice hull, an agricultural waste that is a bane for rice millers and considered a problem by environments, is now a source of cash for farmers. Therefore, it is recommended to the local “Sakurab” farmers to use 10 tons/ha of rice hull as soil amendment and incorporate 5 tons/ha of chicken dung.

The aim of this study is to evaluate the first service pregnancy rate in cows at the selected coastal areas of Bangladesh. The study was conducted during the period from September 2015 to September 2016 in 10 Upazilas in Barisal district of Bangladesh. Data were recorded by checking their record book, collecting information from Upazila Livestock Office and asking the farmer. A total of 1431 cows were selected considering potential factors of, breed, age, parity, body weight, time of artificial insemination (AI) and feeding system. A descriptive analysis expressed as binary logistic regressions were done to measure the association and strength of association of different factors. The overall first AI pregnancy rate (PR/FAI) was 29.1%. The PR/FAI of Local, Cross and Sahiwal breed were 28.3, 30.9 and 20.0%, respectively, In the experiment the PR/FAI of cows aged on 2.0 to 4.0, 4.1 to 8.0, 8.1 to 12 and, 12.1 to 16.0 were 32.5%, 27.2%, 26.2% and 33.3%, respectively the PR/FAI of 100-150, 151-200, 201-250 and >251 kg body weight was 28.5, 30.5, 29.4 and 31.7%, respectively. In this experiment, The PR/FAI of Parity-0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 were 29.3, 30.1, 28.1, 6.9, 27.4, 29.7, 29.4, 32.0, 50.0 and 20.0%, respectively. The PR/FAI at 0 to 8 hr, 8.1 to 16 hr and 16.1 to 24 hr were 39.1, 41.3 and 41.2%, respectively. The PR/FAI of good, moderate and poor feeding system of cows was 45.1, 33.5 and 21.1%, respectively. It may be concluded that the first service pregnancy rate is not significantly influenced by the breed, age and parity of cows. It is suggested that training on dairying with community veterinary care improves the PR/FAI in Bangladesh.

Adoption of Improved Fisheries Technologies by Fish Farmers in Gurara LGA, Niger State, Nigeria
Ajiboye G. E.,
Abdulraheem M. A.,
Alakoso A. A.,
Owolabi M. T.,
Olusanya D. E.
A survey was conducted in Gurara LGA, Niger State, Nigeria to assess the Adoption of Improved Fisheries Technologies by Fish Farmers. A sample of 125 fish farms out of the 250 existing farms identified during the survey was randomly selected for the study. A structured questionnaire was administered to the managers of the selected fish farms to elicit information. Both descriptive and inferential statistics were used to analyze the data. The mean age of the respondents was 40.5 years. Commonly adopted improved fish technologies were floating feeds (84.8%), standard feeding regimes (84.0%), improved breeds of fingerlings (80.0%) and provision of inlet and outlet devices in pond (78.4). Most of the respondents were small-scale producers with a mean stocking rate of 3,789 fingerlings. The study concluded that the use of fish improved technology had positively influenced harvest of catfish farmers in the study area. The study recommends the need to establishing modern fish hatcheries by the fish farmers’ cooperative societies, and other stakeholder agencies so as to supply quality fingerlings. This would reduce cost of production, reduce susceptibility to early mortality, improve the production of fast maturing fish and thereby increase general output level.
