Zinc (Zn) and boron (B) deficiency are widespread nutritional disorders in crop plants, including mustard. However, Zn-B interaction on the performance of mustard crops is not well documented. A field experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, during November 2021 to February 2022 to evaluate the effect of rate and method of Zn and B application on the yield performance of mustard (BARI Sarisha-18). The experiment comprised nine doses of Zn & B as a basal and foliar application viz., recommended Zn (2 kg ha-1) and B (2 kg ha-1) as basal, 75% Zn and B as basal + 25% Zn and B foliar spray at pre- flowering stage, 50% Zn and B as basal + 50% Zn and B foliar spray, 100% Zn and B as basal + 25% Zn and B foliar spray, 100% Zn and B as basal + 25% Zn foliar spray, 100% Zn and B as basal + 25% B foliar spray, 100% Zn as basal (without B), 100% B as basal (without Zn), control (no Zn and B). The experiment was laid out in a Randomized Complete Block Design with three replications. The result revealed that yield was influenced significantly by the rate and method of Zn and B application. The highest plant height (140.57 cm), the maximum number of branches plant-1 (5.84), maximum number of effective pods plant-1 (87.57), maximum number of seeds pod-1(31.53), the highest seed yield (1.85 t ha-1) and the highest stover yield (4.47 t ha-1) were obtained from 100% Zn and B as basal + 25% Zn as foliar. The lowest number of seeds pod -1 (27.20), 1000-seed weight (3.35 g), seed yield (1.33 t ha-1) and stover yield (3.35 t ha-1) were obtained from the control treatment. The result showed that the seed yield of mustard increased with increasing levels of both Zn and B as basal 100% with only Zn 25% as foliar, respectively. Therefore, 100% zinc combined with 100% B as basal and 25% Zn foliar application may be recommended for higher seed yield of mustard (cv. BARI Sarisha-18).
锌(Zn)和硼(B)缺乏症是包括芥菜在内的农作物普遍存在的营养失调症。然而，锌-硼互作对芥菜作物生产性能的影响还没有很好的文献记载。2021年11月至2022年2月，在孟加拉国农业大学Mymensingh农学田间实验室进行了一项田间试验，以评估锌和B的施用量和方法对芥菜(BARI Sarisha-18)产量性能的影响。实验由九个剂量的锌& B作为基底和叶面应用程序即。,推荐锌(2公斤是)和B(2公斤农业作为基底,75%的锌和基底+ 25%锌和B叶面喷雾在开花前的阶段,50%的锌和基底+ 50%锌和B叶面喷雾,100%锌和B基底+ 25%锌和B叶面喷雾,100%锌和B基底+ 25%锌叶面喷雾、100%锌和B基底+ 25% B叶面喷雾,100%锌基底(没有B), 100% B作为基底(没有锌),对照(不含Zn和B)。试验采用随机完全区组设计，3个重复。结果表明，锌和硼的施用速率和方式对产量有显著影响。100% Zn + 25% Zn处理的最高株高(140.57 cm)、最大分枝数(5.84)、最大有效荚果数(87.57)、最大种子数(31.53)、最高种子产量(1.85 t ha-1)和最高秸秆产量(4.47 t ha-1)。对照处理的种子荚数(27.20)、千粒重(3.35 g)、种子产量(1.33 t ha-1)和秸秆产量(3.35 t ha-1)最低。结果表明，随着锌和硼含量的增加，油菜籽粒产量均有显著提高。因此，建议采用100%锌+ 100% B的基施和25%锌的叶面施可以提高芥菜的籽粒产量(cv。巴里Sarisha-18)。

The potential of biochar as a soil conditioner has been approved by scientists worldwide due to its large surface area, high water retention capacity, slow nutrient releasing nature and liming ability; and it might also help to get desirable crop yield in problem soil like acidic soil. Hence, an experimental field trial was operated at the research field of the Department of Agroforestry and Environmental Science, Sylhet Agricultural University, Sylhet to evaluate the performance of banana peel biochar (BB) and orange peel biochar (OB) in the growth and yield of tomato (Solanum lycopersicon Mill.) and country bean (Lablab purpureus) under acidic soil conditions. In case of tomato, plant height (PH), number of leaves plant-1 (NLP), leaf length (LL), and stem diameter (SD) in treatments having different levels of biochar were significantly higher than the control. The maximum PH (72.20 cm), NLP (21), LL (35.66 cm), SD (9.05 cm), and total leaf chlorophyll content (TLCC) (50.56 µmol m-2) of tomato were found in T7 (3% OB w/w + CF) followed by T4 (3% BB w/w + CF) whereas in country bean, the PH (373 cm), NLP (34), branch number (BN) (3), and TLCC (36.65 µmol m-2) were also recorded in T7 followed by T4. The root length (RL) (43.5 cm) and fresh root weight (FRW) (14 g) of country bean were the maximum at T7, followed by T5 (1% OB w/w + CF). According to the results, positive effects of BB and OB application were observed on all the yield parameters of country bean and tomato. The number of pod plant-1 (NPP) (384), individual pod weight (IPW) (5.78 g), total pod weight plant-1 (TPWP) (2220 g), and pod length (PL) (10.57 cm) of country bean were also found to be highest in T7, followed by the T4. Similarly, the highest NFP (37), IFW (55 g), and TFWP (1980 g) of tomato were noted in T7, followed by T4. After the cultivation of country bean and tomato, a significant increase in the soil pH was noticed at T3 (2% BB w/w + CF), T4, T6 (2% OB w/w + CF) and T7 in respect of the control. Therefore, the findings of the study suggest that both BB and OB could have a positive impact on growth and yield components of tomato and country bean by altering soil pH of acidic soil.

To manage necessary amount of food for the growing world population, it is very important to maintain fertility of usual arable land as well as to bring problem soils including sandy soil under coverage of regular crop cultivation. In this context, biochar is a very promising option as soil conditioner and therefore, a plant growth trial in pot was operated at the net house of the Department of Agroforestry and Environmental Science, Sylhet Agricultural University, Sylhet to evaluate the influence of tea waste and sugarcane bagasse biochar on the morphology, yield and yield contributing traits of okra (Abelmoschus esculentus) in sandy soil. The experimental set-up was arranged following randomized complete block design with three replications under eight treatments. The treatments were: T0 (CK, Control, no amendment), T1 (CF, Chemical fertilizers), T2 (2.5 % TWB (tea waste biochar) + CF), T3 (5% TWB + CF), T4 (10% TWB + CF), T5 (2.5% SBB (sugarcane Bagasse biochar) + CF), T6 (5% SBB + CF); and T7 (10% SBB + CF). The results revealed that the different morphological characteristics like plant height (PH), number of leaf plant-1 (NLP), leaf length (LL), plant fresh weight (PFW), and stem diameter (SD) showed no significant difference among the treatments. The highest PH (107.33 cm) and RL (70.67 cm) were found in T0 (CK) whereas the maximum LL (27.33 cm), SD (10.38 mm), and fresh root weight (FRW) (19.67g) were noted in T3. The maximum number of leaves plant-1 (NLP) (20) and PFW (110.67 gm) of okra were observed in T2 and T6, respectively. In case of total leaf chlorophyll content (TLCC), the maximum value was determined in T4 (47 µmol m-2), but the treatments were not significantly different from each other. The number of pod plant-1 (NPP) (23.7), pod length (PL) (18 cm), individual pod weight (IPW) (18 g), number of seed pod-1 (NSP) (45) and pod weight per plant-1 (PWP)(425 g) of okra were found to be highest in T7, followed by T4 and T6. The yield and yield contributing characters of okra showed significantly higher value for biochar treatments (T2 - T7) over to the control (T0) and sole chemical fertilizer treatment (T1). After the cultivation of okra, the highest pH value (7.2) was found in T7, followed by T6. The results of this study might contribute to enlarge the prospects of biochar application in the production of okra and other crops in both normal and less fertile soils.

The planting methods and planting density influence the growth and yield of crops. A field experiment was conducted with split-plot design using two planting methods (row and broadcast) and four planting densities (40, 50, 60, and 70 plants m-2) to observe the effect on yield and yield attributing characters of sesame in the field laboratory of Agronomy Department in Patuakhali Science and Technology University. The yield and yield components were significantly affected by planting methods. The row planting method showed higher yield and yield components than the broadcasting method. The yield and yield components were also affected by planting density. The plant height, the number of branches plant-1, the number of capsule plant-1, and 1000 seed weight were reduced with the increase of planting density except for yield. The highest yield (1358.0 kg ha-1) was obtained from 60 plants m-2 in the row planting method. Row planting method with 60 plants m-2 could be recommended for better yield of sesame.

Dragon is an intensively cultivated fruit crop and its yield is directly influenced by organic manures and lateral branching. So, an experiment was carried out to examine the effects of organic manures and lateral branches pruning on the growth and yield of dragon fruit at the BAU Germplasm Centre of Bangladesh Agricultural University, Mymensingh during the period from March to November, 2022. The experiment consisted of five doses of organic manures, viz. 10.00 kg hill-1 , cow dung, 20.00 kg hill-1 cow dung, 30.00 kg hill-1 cow dung, 40.00 kg hill-1 cow dung and control (no cow dung). There were three types of lateral branches pruning, viz. primary lateral branch pruning, secondary lateral branch pruning and control (no lateral branch pruning). The two-factor experiment was laid out in the RCBD with three replications. The highest plant height (3.70 m), number of branches hill-1 (18.00), number of flowers hill-1 (20.26), number of fruits hill-1 (17.91) and yield (4.84 t ha-1) were obtained from cow dung at 30.00 kg hill-1. In case of primary lateral branch pruning condition, the highest plant height (3.14 m), number of branches hill-1 (14.52), number of flowers hill-1 (15.52), number of fruits hill-1 (14.13) and yield (3.04 t ha-1) were observed. When combined effect was considered the highest plant height (3.87 m), number of branches hill-1 (23.00), number of flowers hill-1 (22.20), number of fruits hill-1 (20.13) and yield (5.26 t ha-1) were obtained from 30.00 kg cow dung with primary lateral branch pruning. When combined effects were considered, the highest yield (5.26 t ha-1) was obtained from 30.00 kg cow dung with primary lateral branches pruning. The lowest values of all the parameters were recorded in the control treatment. The findings of this experiment demonstrated a significant impact of organic manure and lateral branch trimming on the development and production of dragon fruit. Application of 30,00kg cow dung hill-1 with primary lateral branches pruning appears to be a promising combination for producing maximum yield (5.26 t ha-1) of dragon fruit in Bangladesh.
龙果是一种集约栽培的水果作物，其产量直接受到有机肥和侧枝化的影响。为此，于2022年3月至11月在孟加拉国农业大学BAU种质中心开展了有机肥料和侧枝修剪对火龙果生长和产量的影响试验。试验包括5个剂量的有机粪肥，即10.00 kg山头-1牛粪、20.00 kg山头-1牛粪、30.00 kg山头-1牛粪、40.00 kg山头-1牛粪和对照(不施用牛粪)。侧枝修剪分为一次侧枝修剪、二次侧枝修剪和控制(无侧枝修剪)三种。双因素实验在RCBD中布置，重复3次。30.00 kg hill-1牛粪最高株高(3.70 m)、枝数(18.00)、花数(20.26)、果数(17.91)和产量(4.84 t hm -1)。在一次侧枝修剪条件下，最高株高(3.14 m)、分枝数(14.52)、花数(15.52)、果数(14.13)和产量(3.04 t ha-1)。考虑综合效应时，30.00 kg牛粪一次侧枝修剪可获得最高株高(3.87 m)、枝丘数-1(23.00)、花丘数-1(22.20)、果丘数-1(20.13)和产量(5.26 t hm -1)。考虑综合效应时，30.00 kg牛粪一次侧枝修剪获得最高产量(5.26 t hm -1)。在对照处理中记录了所有参数的最低值。本试验结果表明，有机肥和侧枝修剪对火龙果的发育和生产有显著影响。施用3万公斤牛粪hill-1和初级侧枝修剪似乎是孟加拉国火龙果产量最高(5.26吨公顷)的有希望的组合。

So, an experiment was carried out to examine the effects of organic manures and lateral branches pruning on the growth and yield of dragon fruit at the BAU Germplasm Centre of Bangladesh Agricultural University, Mymensingh during the period from March to November, 2022. The experiment consisted of five doses of organic manures, viz. 10.00 kg hill-1 , cow dung, 20.00 kg hill-1 cow dung, 30.00 kg hill-1 cow dung, 40.00 kg hill-1 cow dung and control (no cow dung). There were three types of lateral branches pruning, viz. primary lateral branch pruning, secondary lateral branch pruning and control (no lateral branch pruning). The two-factor experiment was laid out in the RCBD with three replications. The highest plant height (3.70 m), number of branches hill-1 (18.00), number of flowers hill-1 (20.26), number of fruits hill-1 (17.91) and yield (4.84 t ha-1) were obtained from cow dung at 30.00 kg hill-1.

Cauliflower is one of the most important and commercial cole crop in Bangladesh. Cauliflower is a very tasty and much popular vegetable in Bangladesh as well as all over the world. Therefore, the present study was undertaken to investigate the impacts of vermicompost, sawdust, and cowdung on the growth and yield of cauliflower on rooftops, as well as to evaluate the economic performance of various organic manures on cauliflower yield. The experiment was carried out on the sixth floor of housing no. 64, road no. 6/A, Dhanmondi 13 during the period from November 2019 to July 2020. The experiment was designed in CRD having single factor with three replications. The treatments of this experiment were T0= Control (recommended dose of chemical fertilizers), T1= Vermicompost (10 t ha-1) + recommended dose of chemical fertilizers, T2= Sawdust (15 t ha-1) + recommended dose of chemical fertilizers and T3= Cowdung (20 t ha-1) + recommended dose of chemical fertilizers. The seedlings of the cole crop (BARI Fulkopi-2) were collected from Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. Results revealed that the maximum pure curd weight per plant (551.60 g), yield per plot (3.95 kg) and yield per hectare (19.75 t) were obtained from T1 (vermicompost @ 10 t ha-1 + recommended dose of chemical fertilizers) treatment. The benefit cost ratio (BCR) was found to be the highest (3.33) in the treatment of T1 (vermicompost @ 10 t ha-1 + recommended dose of chemical fertilizers). Thus, it was apparent that the vermicompost treatment gave the highest yield per hectare (19.75 t) than the other treatments (sawdust and cowdung) and the highest gross return (Tk. 395000.00). The results clearly showed that rooftops are suitable for cauliflower vegetable production using vermicompost manure to maintain yield as well.
花椰菜是孟加拉国最重要的商业油菜作物之一。花椰菜是一种非常美味的蔬菜，在孟加拉国和世界各地都很受欢迎。因此，本研究旨在探讨蚯蚓堆肥、木屑和牛粪对屋顶花椰菜生长和产量的影响，并评价不同有机肥对花椰菜产量的经济效益。实验在6楼进行。64号路。在2019年11月至2020年7月期间，6/A, Dhanmondi 13。试验采用单因素CRD设计，3个重复。本试验处理T0=对照(化肥推荐用量)，T1=蚯蚓堆肥(10 t hm -1) +化肥推荐用量，T2=锯末(15 t hm -1) +化肥推荐用量，T3=牛粪(20 t hm -1) +化肥推荐用量。油菜(BARI Fulkopi-2)的幼苗收集于加济普尔Joydebpur的孟加拉国农业研究所。结果表明，T1(蚯蚓堆肥@ 10 t ha-1 +推荐用量化肥)处理的单株纯凝块重(551.60 g)、单田产量(3.95 kg)和每公顷产量(19.75 t)最高。结果表明，T1(蚯蚓堆肥@ 10 t hm -1 +推荐用量化肥)处理的效益成本比(BCR)最高，为3.33。由此可见，蚯蚓堆肥处理每公顷产量最高(19.75 t)，比其他处理(锯末和牛粪)和总收益最高(Tk. 395000)。结果清楚地表明，屋顶也适合使用蚯蚓堆肥维持菜花蔬菜的产量。

In Bangladesh, the bitter gourd, which is a vegetable, is a wonderful source of magnesium, folate, zinc, phosphorus, and vitamins B1, B2, and B3. It also contains a high level of dietary fiber. From December 2020 to April 2021, an experiment was carried out in the field laboratory of Bangladesh Agricultural University, Mymensingh, to determine how the polyhouse and the local environment affected the growth and yield of bitter gourd during the off-season. It was a factorial experiment using RCBD (Randomized Completely Block Design), in which Factor A represented the impact of a polyhouse and Factor B represented the influence of the environment on the development and yield of bitter gourd during the off-season. Results showed that photochemically active radiation decreased within the polyhouse compared to the open area outside. In terms of soil temperature, soil moisture, and air temperature, a reverse trend was seen. In comparison to an open field during the winter, the polyhouse had higher air, soil, and soil moisture temperatures. Compared to plants cultivated in open fields, bitter gourd plants planted in poly houses had longer stems, more branches, blooms, and higher reproductive efficiency, which led to more fruit setting plants-1 and a higher fruit yield. Additionally, the fruit size in the polyhouse was greater than it was in the open field situation. In comparison to open fields, the fruit output of bitter gourd was approximately 2.5 times higher in polyhouses, which will be helpful to meet up the nutritional demand in the off-season.

The continuous practice of mono-cropping by small-scale farmers in Bangladesh has resulted in poor soil quality and declining crop yields. As a result, there is a growing need to explore sustainable production methods that are resource-efficient and environmentally friendly. Conservation agriculture has emerged as a beneficial approach that effectively addresses these challenges by utilizing locally available resources to enhance crop productivity and soil quality. With this in mind, the objective of this study was to assess the impacts of conservation agricultural practices on the growth and yield of ginger and turmeric in the Madhupur Garh of Bangladesh. The study was conducted in the Auronkhola, Gaira, Makontonagar in Madhupur district, using a Randomized Complete Block Design (RCBD) with three replications from July to September 2022. Ginger and turmeric were selected for the trial. The results showed that these spices exhibited significantly higher yields (6090 kg/ha and 11370 kg/ha, respectively) compared to traditionally cultivated vegetables in the farmers' fields. The implementation of conservation agriculture practices contributed to the improved yields. As part of conservation agriculture practices, various factors crucial for crop production, such as soil organic matter content, total nitrogen, phosphorus, potassium levels, and pH, were positively influenced. This was achieved through the use of organic manure, minimal tillage, the retention of permanent crop residues, and crop rotation. Based on the findings, the study concludes that traditional agriculture must transition to conservation agriculture methods in order to achieve increased food production while utilizing fewer resources and minimizing negative environmental impacts. This shift towards conservation agriculture offers a more efficient and sustainable approach to farming.

The dispersion in price of rice across different markets in exclusive location, and the astronomic annual increase of 30% in the past 7-8 years in Edo state cannot be attributed mainly to transport costs. Consequently, the study examined spatial price variation of rice vis-à-vis beans, garri, and palm oil as typically consumed substitutes/complements food commodities from a segment of 286 food commodity marketers in Ovia North-East Local Government Area (LGA) of Edo state, Nigeria using the spatial lag model of price-cost of transport data set. The outcomes of the descriptive data showed that the price of 1Kg rice under random test became N1576.82. The consequences of Moran's I (3.652) and Lagrange multiplier exams (10.753) for spatial lag, and Moran's I (0.175) and Geary's c check (0.460) for spatial autocorrelation suggest evidence of clustering in the spatial price of rice at the nearby markets and spatial price of rice between markets than might be under a random experiment. However, the results confirmed no spatial structure, no spatial dependence in the error term, nor spatial dependence within the costs of garri, beans and palm oil. The effects of the spatial lag model showed a mean price of 1kg of rice as N1597.77 with an average total effect of 0.406 comprising 0.274 direct effect and 0.132 indirect effects. Hence, the own-market price of rice in the study area is affected by the across-market price in the nearby markets, in addition to the cost of transportation from market of purchase.
