The organic/inorganic fertilizers can contribute substantial N for sesame, but it is not clear that such nitrogen forms are available for plant uptake. A field experiment at agricultural farm of Nong Lam University in HCMc was conducted to study the effect of four inorganic nitrogen application rates (0, 30, 60 and 90 kg N/ha) in combination with two tons of either cow manure or commercial bio-organic fertilizer (BOF) on growth and yield of sesame. The experiment comprised of 2×4×3 factorial in a Split-plot design with three replications. The results show that two organic fertilizers with low nitrogen contents (5–10 g N/kg) and high C/N ratios (28–30) by themselves are not capable of supplying enough nitrogen for sesame requirement. The additional application of inorganic nitrogen at rate of 30 kg N/ha resulted in maximum plant height (106.4 cm), number of capsules/plant (60.13), weight of capsule (1.01 g), number of seeds/capsule (71.0), weight of 1000 seeds (2.63 g), and highest actual yield (0.85 ton/ha). The combination of organic with inorganic N fertilizer, therefore, needs to consider the effective use of nitrogen from each source to maintaining sesame yield, while avoiding undesirable environmental impacts.

The study examined constraints of pig production in Edo Central Agricultural Zone of Edo State. Data were collected through interview schedule administered to forty one (41) private pig farmers in the study area. Descriptive statistics and multiple regression were used to analyse data for the study. Results showed that majority (85.4%) of the pig producers were male. The stock kept ranged between 1 and 50 pigs for small scale producers who formed 58.4% of surveyed farms, 51-100 pigs for medium scale producers (15%) and above 100 pigs for large scale producers (26.6%). Major obstacles identified among pig producers in the study area were difficulties in securing institutional loans (61.0%), high cost of feed and feed ingredients (46.3%). Flock size (t = 3.313; p = 0.002) had a significant effect on returns accruing to farmers in pig production. Institutional loan scheme to promote pig production should be established and properly managed by government and stakeholders in the livestock industry in Edo State.

Aims: The present work was carried out to break dormancy of microtuber from storage environment for seed potato multiplication as well as regulating their future use.

Study Design: The experiment was laid out in a completely randomized design with three replications.

Place and Duration of Study: The experiment was conducted in the Tissue Culture Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur, Bangladesh during the period of September 2010 to February 2011.

Methodology: The experiment having two factors. First factor; microtuber weight which are graded as S1 = >500 mg, S2 = 250-500 mg, S3 = <250 mg and second factor; seven levels of GA3 viz. G1= 0.0 mg L-1, G2 = 25 mg L-1, G3 = 50 mg L-1, G4 =100 mg L-1, G5 =150 mg L-1, G6 =250 mg L-1, and G7 = 500 mg L-1. To determine the most effective level of GA3 were applied on graded fresh microtuber that had been cold-stored at 4-5°C for 6 week. Sprouting was monitored every 2 days’ interval. Microtubers per treatment were soaked in different concentration of GA3 for 24 h in the light, and then placed for incubation under 16/8 h d/n cycle.

Results: The lowest number of days (13) was taken to induce sprout in case of heavier microtuber and highest number of days (20.44) required for sprouting of smaller microtuber when 500 mg L-1 of GA3 was used. Microtubers exposed to lower concentrations of GA3 exhibited short length sprout. The trend of fresh weights of sprouts decreasing with the decrease of microtuber weight. The microtubers of >500 mg grade produced more sprout mass unit-1 length of sprouts than other two grades.

Conclusion: Microtuber <250 mg has longer periods of dormancy than larger microtubers and breaking their dormancy, 500 mg L-1 GA3 showed superior performance.

The study examined the determinants of poverty coping strategies among women farmers in Yola-South Local Government Area of Adamawa State, Nigeria. A purposive and random sampling technique was employed to select 140 women for the study. Data were collected through the use of structured questionnaire. Both descriptive statistics and inferential statistics were used to analyse the data. The findings revealed that 87.9% of the respondents were within the ages of 20-40 years, educated 89.3% and married 81.4% with household sizes of less than 10 persons (82.2%). Most of the respondents (66.4%) had above 11 years of farming experience. Selling of farm waste, farming, on farm crop processing and fish farming were the poverty coping strategies commonly adopted by the respondents in the study area. The coefficient of determination (R2) was estimated at 0.554 and this indicated that  55.4% of variation of the dependent variable in the model were explained by explanatory variables (age, marital status, household size, level of education, farm size, farming experience, membership of women groups and extension contact). The t-values of the significant variables namely; level of education (X4), farm size (X5), farming experience (X6) and membership of women group (X7) are 6.306529, 2.947541, 2.747442 and 6.030350 respectively. These were all significant at 1% probability level. Among the constraints faced by the respondents include: lack of access to market 27.3%, Women access to fund 24.2%, and poor and crude storage / processing equipment 21.5% and type of crop grown 10.8% were foremost among the constraints. It is recommended that government and other NGOs should come up with policy framework that is targeted at reducing or obliterating the bureaucratic principles that create barriers to women access to bank credit or any source is germane.

An experiment to study the growth of Clarias gariepinus fingerlings fed different practically sourced dietary lipids was conducted with the aim of establishing a preference for either animal or plant lipid for 70 days. Fingerlings with mean weight of 28.66 ± 0.5 g were stocked at random to seven diets in triplicate groups with eachdiet having five fingerlings and were fed with isocaloric and isonitrogenous diets containing 40% crude protein (CP) with varied lipid sources of 8%. Diet 1 (Palm oil), Diet 2 (soya bean oil), Diet 3 (groundnut oil), Diet 4 (Beef tallow), Diet 5 (Pork lard), Diet 6 (Cod liver oil) and Diet 7 as Control (zero oil supplement).

Result showed that there were significant differences (P > 0.05) in feed conversion ratio (FCR) and specific growth rate (SGR) among the Diets. FCR was more efficient in diets containing beef tallow, Ground-nut oil and control (zero oil supplements). Mean weight gain was not significantly different from diets fed with palm oil, soya bean oil, beef tallow, and control (no oil supplement) based diet. Diets fed with groundnut oil and pork lard were significantly (P < 0.05) different from diets fed with cod liver oil. Mean weight gain was higher in fish fed with pork lard and beef tallow (9.85% and 9.01%) respectively and lowest in fish fed with cod liver oil (7.39%). Relative weight gain (RWG) showed no significant difference (P > 0.05) between fish fed with palm oil and soya bean oil based diets. However, fish fed with cod liver oil, beef tallow and control (zero oil supplements) based diet were significantly different (P < 0.05) from fish fed with pork lard based diet.

The platform for organic agriculture (OA) implementation has great potentials in the Philippines. Various researches on OA had been conducted because organic crops are one of the most important needs of Filipinos. A study was conducted to determine the status and trend of the organic agriculture (OA) research and development (R and D) programs in Bicol Region, Philippines. Specifically, it aimed to conduct inventory and determine the trends of R and D projects on organic agriculture, determine the information needs of OA stakeholders and identify research gaps and propose strategies to enhance the OA R and D programs. A survey using purposive sampling was undertaken to 149 stakeholders to know their information needs and secondary data was gathered on OA researches. Result of the study revealed that 46 projects were implemented and most of the researches conducted were on production aspect. Highest percentage (34%) recorded in terms of information needs of the stakeholders were on demand and supply. Research gaps identified were absence of a whole research chain on organic agriculture for a specific commodity, lack of a research with component on developing a centralized, web-based information system, and inadequate research on policy and governance on OA. While considerable effort had been done on researches related to organic agriculture, a more focused action research on market opportunities and market knowledge is needed and imperative to ensure the effective and successful implementation of the OA program in the Bicol region. This should be coupled with continued aggressive information dissemination campaign to firm up appreciation and strengthen awareness of stakeholders on organic agriculture.
