This study aims to critically bring to the fore appropriate soybean production technologies that boost the level of farm productivity. Multistage sampling techniques were used in selecting respondents for this study. Primary data was collected using structured questionnaires. Descriptive statistics and Multinomial Logit regression model were the analytical techniques employed. The results indicated that most (35%) were within the age bracket of 21-30 years; 39.7% had farming experience of 1-5 years. Most (73.3%) had extension contact; most (75%) were married, and most (63.3%) were male. Furthermore, most (55%) had farm size of ≤1.9 hectares; most (38.3%) had household size of 11-30 people. Also, planting on ridges (80%), use of viable seeds (79.2%) and recommended harvesting time (50.0%); were the prevalent soybean production technologies adopted in the study area. In addition, the coefficient of multiple determinations (R2) was 0.7831 suggesting that 78% of the variation in the soybean farmer’s adoption decision was accounted for by the variables in the regression model. The remaining 22% is attributable to omitted variables and the stochastic error term. Furthermore, the most significant constraints of adoption of soybean production technologies were; high cost of technology (68.3%), lack of technical expertise (50.8%), inadequate capital (40.8%), and poor market linkages (40.0%). Thus, this study revealed that socioeconomic variables

Tea is an important food drink globally with significant health benefit. However, it consumption is low in Nigeria and sub-Saharan Africa generally. There is dearth of literature on branded tea demand. Hence, household demand for branded tea in southwest, Nigeria was investigated. The study revealed the dominance of Lipton tea among other brands of tea. Demand for herbal tea was higher among older respondents. The study affirmed that the monthly household expenditure share on branded tea in the study area and across the states was low. The monthly household expenditure on complements (sugar, milk and honey) was higher than that of branded teas. The study revealed the influence of price on the expenditure shares of branded teas, its substitutes and complements. Marital status and years of education of respondent influenced the decision to consume branded tea. Expectedly, branded teas exhibited complementary relationships with milk, sugar and honey.

Snails are an emerging problem in banana production in Cameroon due to the damages caused on the banana fruits. They attack the banana fruits resulting in aesthetically disfigured fruits. This study was carried out to compare the effectiveness of selected agrochemicals in the laboratory and the field for the control of the snails. The agrochemicals compared were Bromorex ® (chilli pepper extracts), Potassium Nitrate, Vydate ® (Oxamyl), and Limace ® (Metaldehyde). Laboratory results showed that snail mortality caused by the different treatments after 7 and 14 days was highest for Limace (37% and 100% respectively). Limace® had the highest mean percentage (86.4%) of snails at the snail zone as compared with the control (6.1%) which was the least. Field results showed that plants treated with Limace ® had the lowest mean number of snails counted on the corms and pseudostems during the 12-week period while the Control (2.67snails/plant) had the highest mean value followed by Bromorex ® . But the mean number of living snails with plant treated with Potassium Nitrate, Vydate ® and Limace ® increased from the 10 th week albeit less than 1 snail/plant. During the first three weeks plants treated with Limace ® and Vydate ® the number of dead snails was relatively higher (1.6 snails/plant and 1.08 snails/plant respectively). Of the four treatments assessed, Limace ® was most effective in the management of snails followed by Vydate ® . Limace ® controlled the snails best both in the laboratory and on the field at concentrations of 5 g per container (7x7x13 cm) and 50 g per banana mat respectively.
蜗牛是喀麦隆香蕉生产中一个新出现的问题,因为蜗牛对香蕉果实造成了损害。它们攻击香蕉水果,导致香蕉水果在美学上毁容。本研究比较了实验室和田间选用的农药防治钉螺的效果。比较的农药是Bromorex®(辣椒提取物)、硝酸钾、Vydate®(Oxamyl)和Limace®(Metaldehyde)。室内试验结果表明,不同处理后7 d和14 d的钉螺死亡率以石灰处理最高,分别为37%和100%。在钉螺区,Limace®的平均钉螺百分率最高(86.4%),而对照组的平均钉螺百分率最低(6.1%)。结果表明,在12周的时间内,Limace®处理的植株球茎和假茎上的平均蜗牛数最少,而对照的平均值最高(2.67只/株),其次是Bromorex®。但从第10周开始,施用硝酸钾、Vydate®和Limace®的钉螺的平均活螺数有所增加,尽管低于1只/株。在前三周,Limace®和Vydate®处理的植株死螺数量相对较高(分别为1.6只/株和1.08只/株)。在评估的四种处理中,Limace®对蜗牛的管理最有效,其次是Vydate®。Limace®在实验室和田间控制钉螺的效果最好,浓度分别为每个容器(7x7x13 cm) 5 g和每个香蕉垫50 g。

A study was conducted with an overall objective of establishing the determinants of weevil resistance in maize. Field experiments were done at GART using a North Carolina Design II with three replications and also at Nanga research in Mazabuka. Laboratory experiments were conducted at Zambia Agriculture Research Institute (ZARI) Entomology laboratory and University of Zambia, Food Science Department where insect bioassay and the biochemical tests were done respectively. In the insect bioassay grain hardness, grain weight loss, median development period, F1 progeny emergence and the Dobie index of susceptibility indices were measured. Protein and the Phenolic content were determined under the biochemical tests among genotypes. They were highly significant differences in all the twenty seven genotypes evaluated. Results showed that Parental survival accounted for 78.5 % of the total variation, Phenolic content was strongly and positively correlated (r = 0.423***) with grain hardness providing a good measure of resistance accounting for the 10.9 % of the total variation. The study showed the possibility of breeding maize genotypes with an increased resistance and also susceptible lines had a decreasing Phenolic content but increasing Phenolic content resulted in increased resistance. It was therefore concluded that Phenolic content and parental survival can be used as an indirect selection criteria for weevil resistance. Contribution/Originality: This study is one of very few studies which have investigated the development of the Host-plant resistance as a pest control method is safe, method to farmers and most compatible with other components in the Integrated Pest Management initiatives.
进行了一项研究,其总体目标是确定玉米对象鼻虫抗性的决定因素。现场实验是在GART使用北卡罗来纳设计II进行的,有三个重复,也在Mazabuka的Nanga研究中心进行的。实验室实验在赞比亚农业研究所昆虫学实验室和赞比亚大学食品科学系进行,分别进行昆虫生物测定和生物化学试验。在昆虫生物试验中,测定了籽粒硬度、籽粒失重、中位发育期、F1代出苗率和敏感性指标的多比指数。通过生化试验测定不同基因型的蛋白质和酚类物质含量。在所有27个基因型中均存在高度显著差异。结果表明,亲本存活率占总变异的78.5%,酚含量与籽粒硬度呈显著正相关(r = 0.423***),是衡量抗性的良好指标,占总变异的10.9%。研究表明,选育抗性增强的玉米基因型是有可能的,而且易感品系的酚含量降低,但酚含量增加导致抗性增强。综上所述,酚含量和亲本存活率可作为筛选象鼻虫抗性的间接标准。贡献/独创性:本研究是为数不多的研究寄主-植物抗性发展的研究之一,因为一种害虫控制方法是安全的,对农民来说是一种方法,并且与害虫综合管理计划中的其他组成部分最兼容。

An experiment was carried out to investigate the influences of seven levels of antioxidants on BARI Mistimorich-1 and BARI Mistimorich-2 varieties of sweet pepper at the Central Research Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. Antioxidants were applied to sweet pepper varieties which had a significant effect on physiology, yield and quality of sweet pepper. Among those treatments, ascorbic acid (AA) at 200 ppm with salicylic acid (SA) at 200 ppm was more potential to enhance chlorophyll a (30%), chlorophyll b (39.39%), total chlorophyll (33.73%), number of flower plant-1 (17.63%), number of fruits plants-1 (56.73%), fruit yield plant-1 (43.61%), total soluble sugar (28.67%) and vitamin C (22.75%) compare to control. The variety of BARI Mistimorich-2 produces 4.55% higher fruit yield than BARI Mistimorich-1.

The study assessed the value chain analysis of lentil in some selected areas of Bangladesh. Data were collected from 96 randomly selected lentil farmer, local trader, arathder, retailer and dal miller from Jashore, Jhenaidah and Kushtia district. The results indicated that most of the farmer of the study areas were cultivated BARI masur-8, BARI masur-7 and BARI masur-6 which were popular and prominent variety release from BARI. On an average, total production cost of lentil was Tk. 66373.83/ha, whereas variable cost was Tk. 35404.16/ha and fixed cost was Tk. 30969.68/ha. Average yield of lentil was 1.632 ton/ha in the study areas. Gross return was Tk. 115863.29/ha and net return was Tk. 49489.46/ha. Benefit cost ratio was 1.75 that means the lentil cultivation was profitable. Milling of 1 MT lentil at dal mill then it get 725 kg pulse (lentil) and 200 kg was husk (bran). Marketing cost of faria, bepari, wholesaler and retailer was Tk. 855/mt, Tk. 750/mt, Tk.5295/mt and Tk. 1580/mt respectfully. Retailer net margin was highest (Tk. 4945/mt) but they sold daily average 9.28 kg lentil only. Retailer was the highest value added Tk.6525/mt (44.85%) followed by wholesaler Tk.5525/mt (37.97%), faria (10.31%) Contribution/Originality: This study is one of very few studies which have investigated on the value chain, value addition and intermediaries involved in lentil value chain system of Bangladesh. This study also document about which variety of lentil was cultivated and profitability of lentil cultivation in Bangladesh.
该研究评估了孟加拉国一些选定地区扁豆的价值链分析。数据从Jashore、Jhenaidah和Kushtia地区随机选择的96名扁豆农民、当地贸易商、零售商和dal磨坊主中收集。结果表明:研究区大部分农民种植BARI 8号、BARI 7号和BARI 6号,这是BARI释放的热门和突出品种。平均而言,小扁豆的总生产成本为66373.83塔卡/ha,可变成本为35404.16塔卡/ha,固定成本为30969.68塔卡/ha。研究区小扁豆平均产量为1.632吨/公顷。总收益为115863.29塔卡/公顷,净收益为49489.46塔卡/公顷。效益成本比为1.75,说明扁豆种植是有利可图的。在扁豆磨坊研磨1吨扁豆,然后得到725公斤脉冲(扁豆)和200公斤外壳(麸皮)。faria、bepari、批发商和零售商的营销成本分别为855塔卡/吨、750塔卡/吨、5295塔卡/吨和1580塔卡/吨。零售商净利润率最高(4945塔卡/吨),但他们平均每天只销售9.28公斤扁豆。零售商是最高的附加值6525吨(44.85%),其次是批发商5525吨(37.97%),faria(10.31%)贡献/原创性:本研究是对孟加拉国扁豆价值链系统中涉及的价值链,增值和中介机构进行调查的极少数研究之一。本研究还记录了孟加拉国种植扁豆的品种和扁豆种植的盈利能力。
