The experiment consisted of three onion cultivars of Bangladesh viz. Taherpuri, BARI Piaz 1 and BARI Piaz 4, and five household organic mulches, viz. T0 = Control (no mulching), T1 = vegetables wastes, T2 = rice straw, T3 = banana leaf and T4 = water hyacinth. The two-factor experiment was carried out in Randomized Complete Block Design with 3 replications. Results revealed that the parameters under study showed significant variation between onion varieties and mulching. Results showed that the highest percent of weight loss of bulbs (31.19%) was observed in V3T4 followed by V3T1 (29.89%) and the lowest percentage of weight loss of bulbs (24.66%) was observed in V1T1. The highest percentage of dry matter content of bulb (13.13%) was recorded in V3T4 followed by V3T1 (12.54%) and the lowest percent dry matter content of bulb (8.08%) was observed in V1T0. The highest percentage of splitted bulb (10.33%) was observed in V3T4 followed by V3T1 (9.33%) and the lowest percentage of splitted bulb (1.33%) was observed in V1T0 (Table 4).

The objective of the study was to pre-scale up and popularize the best-performing and preferred groundnut variety in the study area. The study addressed a total of 90 farmers in the two years of the project span. From a total of 90 farmers, male represents 73 and female 17. During farmers’ selection process, both female and male farmers were incorporated so as to avoid gender bias. Training was given to the selected farmers, development agents and district experts about improved groundnut technologies production and management. Full packages of the technologies were provided. Variety Manipinter was planted on plot area of 0.25ha on respective farmers’ field in the study area. The recommended rate of NPS 100kg/ha and Row planting method with the spacing of 60cm between rows and 10cm between plants were used respectively. To enhance farmer’s knowledge on Groundnut training was given for target community on agronomic practice of Groundnut. During training a total of 117 target communities were participated on training out of which 84 were male and 33 were male. An average production of 14.935 qt/ha and a total of 336 quintal of groundnut yield was harvested during project life span. Finally, farmers feedback concerning technology was collected and incorporated, accordingly the farmers feel as the Manipinter have relatively high yield, good seed quality (Grain size, color), disease tolerant than previously used varieties. Generally, since it is impossible to address all farmers only by the effort of the research center, district agriculture and natural resource bureau in collaboration with zonal agricultural and natural resource office and input supplying NGO’s should hold the turn to scale up the technology in wider scale.

Due to environmental conditions such as distribution and length of the rainy season shifting from time to time elsewhere, particularly at Gode and Ardayita seed production farm, sowing timing and varietal selection are key factors for low yield of wheat crop. This Experiment was designed in a randomized complete block design with three-replications which contain four sowing dates, ranging from June 17 to July 18 at ten-day intervals, and four wheat varieties namely Kingbird, Hidase, Picaflor, and Ogolcho combined to form 16 treatments. According to the result, on days to heading, there was a significant interaction effect of variety and location and the highest number of days (70.42) was obtained at the Ardayita location on Kingbird variety. On the day of heading, there is also a substantial interaction effect of location and sowing date, the maximum days (72.00) were observed at Ardayita on the early sowing date (June-17). The maturity dates of the two locations varied significantly, the longer (116.17) days were recorded at Ardayita. The effect of variations on days to maturity of varieties also significant, Ogolcho variety had the highest maturity (120.04) days. Date of sowing also has a significant effect on maturity date; the highest number of days (116.96) was recorded on June 17 sowing date. The grain filling period significantly vary among the varieties, the Ogolcho variety had the highest number of days (53.25). Grain filling period also had significant variation on date of sowing; the earliest sowing date (June 17) has the longest date (49.96). On the other hand, location had no effect on the grain-filling period, plant height and seed yield. Sowing date and location significantly interact on grain yield of wheat. The maximum (6.38 ton ha-1) seed yield was recorded at Gonde location on second (June 28) sowing date and Ardayita place obtained highest yield at first sowing date (June 17). There was a significant interaction between sowing date and varieties on yield of wheat. From the result Hidasse variety obtained highest yield (6.58 ton ha-1) on the second sowing date (June 28) whereas the Ogolch variety recorded highest (6.28 ton ha-1) at the first sowing date (June 17).

A total of 60 early variety country bean-growing farmers were selected from three villages of Chatmohar upazila using a simple random sampling technique. Stochastic frontier production function was applied to determine the technical efficiency of the country bean growers. Technical inefficiency effects model was also applied to identify the demographic and socio-economic factors by which inefficiency effects are influenced. The study revealed that Benefit Cost Ratio (BCR) was the highest (2.29) for large farmers followed by medium (2.27) and small farmers (2.21). The result of the Maximum Likelihood Estimates (MLE) showed that human labor, fencing and manure had significant positive impact whereas the irrigation and insecticides had a negative impact on the production of country bean. The results of technical inefficiency effect model showed that farmer’s age, farm size had negative impact while education, family size and farm credit had positive impact on technical efficiency. The inefficiency analysis results indicated that farm level technical efficiency ranged between 43.06% and 98.01% with a mean technical efficiency of 91.9% implied that there was potential to increase country bean production among smallholder farmers in the study area by 8.1% through efficient use of present technology. The main constraints to country bean (early variety) production were identified as- infestation of pest and disease, high price of inputs, paucity of quality seed and fertilizer, scarcity of human labor, lack of technical knowledge, limited access to institutional credit etc. Despite the constraints, there is a great prospect of early variety country bean production in the study areas. Country bean (early variety) production could be increased in a sustainable manner if farmers would be provided with government support regarding lower price of input, fair price of output, marketing facilities, training for farmers and farm credit at low interest rate, reducing the activities of syndicate of middlemen. Government should provide necessary support to the farmers for ensuring sustainable production of early varieties of country bean. Res. Agric. Livest. Fish.

This review discusses the significance of the jute crop and the advantages of nutrient management techniques in the jute and allied fibre crops (JAF), which increase output, fecundity, and output to fulfill the nation’s potential fibre requirements. Due to the demand for JAF fibres in the production of various goods, fibres make a significant economic contribution to Bangladesh. It not only gives the rural population a job, but it also generates cash for the area. If integrated nutrient management strategies are used, it will be simple to meet future demand for jute-based products while still preserving agriculture. Res. Agric. Livest. Fish.
