An experiment was conducted at the research field in the Department of Agriculture, Noakhali Science and Technology University, Noakhali, Bangladesh during the period from March to July 2022 to study the effect of vermicompost on growth and yield of okra. The experiment was laid out in a Randomized Complete Block Design (RCBD) comprising four treatments with three replications. The four treatments were T0 (Control), T1 (Vermicompost 10 t ha-1), T2 (Vermicompost 15 t ha-1) and T3 (Vermicompost 20 t ha-1). Green finger F1 okra used as planting material. Data were recorded from different stages of plant growth viz, plant height, days of flowering, fruit per plant, fruit length, fruit diameter, fruit weight, fruit weight per plant, yield per plot and yield per hectare. All the recorded parameters were statistically significant (P<0.01). The maximum days to first flowering (47.31 days) was recorded from T0 (Control), while the minimum days for first flowering (40.67 days) was found from treatment T3 (Vermicompost 20 t ha-1). The maximum height of okra plant (100.43 cm), number of fruits per plant (22.13), fruit length (13.60 cm), fruit diameter (2.01 cm), fruit weight (13.47 g), fruit weight per plant (198.02 g), yield per plot (1.78 kg), yield per hectare (17.8 t ha-1) were found in treatment T3 (Vermicompost 20 t ha-1) whereas lowest data recorded in treatment T0 (Control). Observing the results, it can be stated that application of vermicompost @ 20 t ha-1 for okra cultivation gave better growth and yield in the coastal area of Bangladesh. Res. Agric. Livest. Fish.

An experiment was conducted to study the effects of varieties and household organic mulches on growth and yield of onion at the Horticulture Farm of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period from October 2020 to March 2021. 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). On the other hand, the highest percentage of rotten bulb (9.00%) was observed in V3T0 followed by V2T0 (8.33%) and the lowest percentage of rotten bulb (2.00%) in V1T2. Therefore, the combined use of water hyacinth along with Taherpuri was found to be better with respect to the quality and storability of onion. Res. Agric. Livest. Fish.

An experiment was carried out from May to September, 2018 to determine the suitable species combination of two indigenous fish Pabda (Ompok pabda) and Gulsha (Mystus cavasius) with Rohu in farmer’s pond. Three species combinations (% of total stocking densities) Gulsha: Pabda = 60: 40 at T1, 40: 60 at T2, and 50: 50 at T3 were tested. Stocking of Rohu were similar (2964/ha) for all the treatments. Similar stocking density (200564/ha) was maintained in all the treatments. The production obtained were 7138.30±63, 6977.75±78 and 7037.03±84 kg/ha from T1, T2 and T3 respectively. The highest production was obtained from T1 compared to other treatments. A straightforward economic analysis showed that treatment T1 (BCR -1.94, net profit: Tk.12,94,576/ha/6 months) had the highest benefit-cost ratio (BCR) and net profit, subsequent to treatment T3 (BCR -1.87, net profit: Tk.12,74,685/ha/6 months) and treatment T2 (BCR-1.93, net profit: Tk.12,02,956/ha/6 months). Therefore, it might be concluded that the species combination of pabda, gulsha and rohu followed by T1 may be a better option considering the production and economic benefits to farmer’s ponds in our country.

Salinity is a serious environmental issue that reduces the yield of vegetable crops. Brinjal is one of the world's most popular vegetable crops and its productivity and quality are heavily influenced by the salt content in the root area. Plant growth regulator management, however, is a key factor that can be used to increase brinjal production in moderate saline soils. The experiment was carried out at the Agricultural Research Field, Noakhali Science and Technology University, Noakhali, Bangladesh during the period from January to June 2022, to observe the effect of plant growth regulators on growth, yield, and yield contributing characters of brinjal (Solanum melongena L. V: Purple king ). The experiment was followed Randomized Complete Block Design (RCBD) comprising four treatments with three replications. The treatments were T0 (Control), T1 (Salicylic acid @ 60 ppm), T2 (Gibberellic acid @ 60 ppm), T3 (Naphthalene acetic acid @ 60 ppm). Data were recorded from different stages of plant growth viz, plant height, number of leaves per plant, number of branches per plant, number of fruits per plant, fruit length, fruit diameter, fruit weight, and yield. The maximum plant height (100.00 cm), number of leaves per plant (197.17) , number of branches per plant (17.17), number of flowers per plant (62.67), number of fruits per plant (34.42), fruit length (25.50 cm), fruit diameter (3.33 cm), weight of fruit (92.67 g), yield per hectare (22.17 t ha-1) were measured from treatment T2 (GA3 @ 60 ppm). Results conclude that the application of gibberellic acid @ 60 ppm for brinjal cultivation gave better growth and yield in moderate saline soils. Res. Agric. Livest. Fish.

The study was conducted in Dale sadi, Dale wabera and Sayo districts of Kellem wollega Zone and Gimbi districts of west Wollega zone for two consecutive years of production(2016/17 and 2017/18 G.C ) on farmers’ field. 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.

Wheat is one of Ethiopia's main foods, contributing to daily caloric consumption. 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).

In Bangladesh calves are affected by several types of diseases and most of them are parasitic, infectious, metabolic or nutritional, surgical affection etc. causing severe economic losses in every year. The study was conducted to investigate the epidemiological status of calves’ diseases with relation to age and seasonal variation at Jhenaidah district, Bangladesh. A total of 12525 clinical cases were registered in all 6 Upazila of Jhenaidah district for the clinical diagnosis and therapeutic purposes during a period of two years, which were analyzed to evaluate the prevalence of clinical diseases in calves. Each of the clinical case was diagnosed on the basis of history, general examination, physical examination and clinical findings. Among the recorded cases the highest prevalence of clinical cases in calves were found to be round worm infestation ( 14.80%), and followed in descending order by non-specific diarrhoea ( 9.20 %), liver fluke infestation ( 8.34%), anorexia ( 7.95%), lice infestation ( 6.66%), debility (6.42%), wounds (4.68 %), tick infestation (3.93 %), tape worm infestation (3.54%), non-specific fever & navel ill (3.42%), coccidiosis (3.35%), conjunctivitis (3.16%), FMD (2.83%), pneumonia (2.49%), allergy/skin disease (2.30%), coldness (2.06%), tympany/bloat (1.71%), calf-scour (1.61%) etc. Among the general clinical disorder, the highest prevalence of clinical cases was non-specific diarrhoea (9.20%), among parasitic disease the highest prevalence was round worm infestation (14.80%), among infectious disease the highest prevalence was coccidiosis (3.35%), among surgical affection the highest prevalence was wound (4.68%). The influence of age and season on the occurrence of these diseases was considered. Immuno prophylaxis and hygienic management should be introduced to curtail the prevalence of calf diseases and disorders. So more epidemiological and intensive laboratory study should be needed to confirm the etiology, prevention and control measures of the diseases and disorders in cattle at the study area. Res. Agric.

The present study was undertaken to measure the profitability and technical efficiency of early variety country bean cultivation in selected areas of Chatmohar upazila of Pabna district. 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. Vol. 10, No. 2, August 2023: 155-164
本研究是在帕布纳县Chatmohar upazila选定的地区进行的,旨在衡量早品种国家豆类种植的盈利能力和技术效率。采用简单的随机抽样技术,从Chatmohar upazila的三个村庄中选择了60名早期品种的国家豆类种植农民。应用随机前沿生产函数确定了农村豆农的技术效率。运用技术无效率效应模型分析了影响技术无效率效应的人口因素和社会经济因素。结果显示,大型农户的收益成本比(BCR)最高,为2.29,其次是中型农户(2.27)和小型农户(2.21)。最大似然估计(MLE)结果表明,人工、围栏和肥料对豆荚产量有显著的正向影响,而灌溉和杀虫剂对豆荚产量有显著的负向影响。技术效率低下效应模型结果显示,农民年龄、农场规模对技术效率有负向影响,而教育程度、家庭规模和农场信贷对技术效率有正向影响。低效分析结果表明,农户水平技术效率在43.06% ~ 98.01%之间,平均技术效率为91.9%,表明研究区小农通过有效利用现有技术,有可能将国家大豆产量提高8.1%。确定了影响国家大豆(早品种)生产的主要制约因素是病虫害肆虐、投入品价格高、优质种子和肥料缺乏、人力短缺、缺乏技术知识、获得机构信贷的机会有限等。尽管存在诸多制约因素,但研究区早品种国家豆的生产前景广阔。如果政府在降低投入价格、公平的产出价格、销售设施、对农民的培训和低息农业信贷等方面向农民提供支持,减少中间商集团的活动,就可以以可持续的方式增加国家豆类(早期品种)的生产。政府应向农民提供必要的支持,以确保早期豆品种的可持续生产。阿格利司》。力所能及的。鱼。第10卷,第2期,2023年8月:155-164

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.

Jute is well-known for its distinctive versatility in Bangladesh and comes in first place in terms of output, which illustrates the jute crop's dual character of quantity and quality. 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.
