The study was carried out to evaluate some sesame varieties under different nutrient levels for enhancing the productivity of sesame during March – June, 2014. The experiment was carried out in a split-plot design with three replications. The main -plot treatments had four nutrient levels viz., 75% of the recommended dose of fertilizer(RDF), 100% RDF, 125% of RDF, and 150% of RDF, and the sub - plot treatments included six sesame varieties viz., Laltil (Local), Atshira (Local), T6, BARI Til-3, BARI Til-4 and Binatil-2. RDF indicates a nutrient schedule of 56:72:23 kg N, P2O5, and K2O ha-1. The effect of nutrient levels, varieties, and their interaction showed significant variation in respect of yield contributing parameters, yield, and harvest index. Results revealed that in nutrient levels, 100% of RDF produced the highest seed yield (1223 kg ha-1). The least seed yield was observed with 150% of RDF (924 kg ha-1). Among the sesame varieties,BARI Til-4 showed the optimum growth and yield contributing parameters as a result highest seed yield (1170 kg ha-1). The lowest seed yield was obtained from Laltil (811.30 kg ha-1). The interaction effect was found significant where highest seed yield of 1481 kg ha-1 with 100% of RDF combination of sesame var.

Intercropping is the option of growing more crops in the same piece of land for additional profit and to mitigate the losses or failure of the main crop. Considering this view, an experiment was designed to observe the growth and yield performance of spinach as an intercrop with bottle gourd as leafy vegetable under various planting method to increase productivity and economic return. The study included four planting systems viz; broadcasting spinach with bottle gourd, line sowing spinach with bottle gourd, sole bottle gourd and sole spinach followed by RCB design with three dispersed replications. Based on the growth and yield performance with economic return, intercropping performed better than sole cropping. The higher bottle gourd equivalent yield (15.67 to 28.36 %) was obtained in line sowing of spinach with bottle gourd than sole bottle gourd. The land equivalent ratio (LER) showed a positive influence on intercropping systems compare to monoculture. The maximum gross return (Tk. 430000 ha-1), gross margin (Tk. 325000 ha-1) and BCR (4.10) was obtained from line sowing of spinach with bottle gourd. This practice could be able for better return with the same input and using the same area of land with minimum risk. Bangladesh Agron. J. 2021, 24(2): 91-97

A pot experiment was conducted inside a rain- shelter in the Department of Agronomy, Sher-e-Bangla Agricultural University, Dhaka in 2016 to evaluate the arsenic (As) stress tolerance of seven lentil varieties, viz., BARIMasur-1, BARIMasur-2, BARIMasur-3, BARIMasur-4, BARIMasur-5, BARIMasur-6 and BARIMasur-7 against three levels of arsenic stress viz., no arsenic stress (control), 25 mg As / kg soil and 50 mg As / kg soil. Arsenic treatment was imposed during pot filling with 10 kg air- dried soil pot-1. The pots were fertilized with 0.225 g urea, 0.425 g TSP and 0.175 g MoP pot-1 before seed sowing. Six healthy seeds of seven lentil varieties were sown in each pot and the plants were thinned to four after three weeks later. It was observed that increasing levels of As significantly decreased pods plant-1, 1000 seeds weight, seed yield, stover yield, harvest index and relative values of these parameters, whereas increased seed arsenic content and relative seed arsenic content in all the lentil varieties studied. Although BARIMasur-7, BARIMasur-6 and BARIMasur-5 gave the higher seed yield, their relative seed yield, relative values of yield components, relative stover yield and relative harvest index were lower, but seed arsenic content and relative seed arsenic content were higher compared to that of BARIMasur-1, BARIMasur-2, BARIMasur-3 and BARIMasur-4. Therefore, BARIMasur-1, BARIMasur-2, BARIMasur-3 and BARIMasur-4 varieties were superior and safe for consumption considering seed arsenic content and suitable for breeding considering relative seed arsenic content under soil arsenic stress conditions. Correlation studies indicated that As stress decreased relative seed yield by most negatively influencing the relative 1000 -seeds weight followed by relative pods plant-1, relative stover yield and relative seeds pod-1.

The application of biochar may enhance the yield of potato for different processing categories. A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka-1207, during the period from November, 2020 to April, 2021 to find out the response of biochar on yield of potato for different processing categories. The experiment comprised of Potato varieties (3): V1: BARI Alu-29 (Courage), V2: BARI Alu-28 (Lady Rosetta) and V3: BARI Alu-25 (Asterix) and Biochar level (5): B0: 0 t ha-1, B1: 2.50 t ha-1, B2: 5.00 t ha-1 and B3: 7.50 t ha-1 and B4: 10 t ha-1. The study was laid out in a randomized complete block design with 3 replications. The results showed that biochar amendment could enhance the yield of processing category potato. The total yield and marketable yield of potato gradually increased with increasing biochar level. The results also revealed that the processing category potato viz., canned, chips and French fry potato yield progressively increased with advancing biochar level irrespective of varieties except dehydrated category. In case of marketable yield, BARI Alu-25 and BARI Alu-29 with biochar level 5 to 10 t ha-1performed superior than other combinations and produced 19.50 to 21.30 t ha-1which are 18.54 to 36.45% higher than without biochar. The combination of V2B4 produced maximum canned (8.10 t ha-1) and dehydrated potato (10.09t ha-1) but V3B4 made significantly highest chips (9.03 t ha-1) and French fry (5.70 t ha-1) potato, whereas, BARI Alu-29 and BARI Alu-28 did not produce any French fry category potato. However, the level of biochar of 5 to 10 t ha-1 could enhance processing category potato production. It may be concluded that potato growers may apply biochar along with recommended rate of other fertilizers for producing maximum processing category potato. Bangladesh Agron. J. 2021, 24(2): 63-72
生物炭的应用可以提高不同加工类别的马铃薯产量。2020年11月至2021年4月，在达卡的Sher-e-Bangla农业大学进行了一项田间试验，以了解生物炭对不同加工类别土豆产量的影响。该试验包括马铃薯品种（3）：V1:BARI Alu-29（勇气）、V2:BARI Alu-28（罗塞塔夫人）和V3:BARI Alu-25（Asterix）以及生物炭水平（5）：B0:0 t ha-1、B1:2.50 t ha-1，B2:5.00 t ha-1和B3:7.50 t ha-和B4:10 t ha-。本研究采用随机完全区组设计，共3次重复。结果表明，生物炭改良剂能提高加工类马铃薯的产量。随着生物炭水平的提高，马铃薯的总产量和商品产量逐渐增加。结果还表明，除脱水类外，加工类马铃薯，即罐装马铃薯、薯片和炸马铃薯的产量随着生物炭水平的提高而逐渐增加。在市场产量的情况下，具有5至10吨ha-1生物炭水平的BARI Alu-25和BARI Alu-29表现优于其他组合，产生19.50至21.30吨ha-1，比没有生物炭的情况高18.54至36.45%。V2B4组合生产的罐装土豆（8.10吨ha-1）和脱水土豆（10.09吨ha-1。然而，5至10t ha-1的生物炭水平可以提高加工类马铃薯的产量。可以得出的结论是，马铃薯种植者可以将生物炭与推荐的其他肥料一起施用，以生产最大加工类别的马铃薯。孟加拉国Agron。J.2021，24（2）：63-72

In Bangladesh direct-seeded Aus rice is a conventional rice cultivation practice and weed infestation is a severe problem in direct-seeded rice production due to the existence of favorable environment during this period. So, by minimizing the use of herbicides and replace them with eco-friendly and environmentally sustainable herbicides based on natural plant products or allelochemicals, a factorial experiment based on randomized complete block design with three replications was performed at the research field of Bangladesh Rice Research Institute (BRRI), Gazipur, Bangladesh from July 2018 to August 2019 to evaluate effect of sunflower crop residue on weeds growth and yield of direct seeded Aus rice in Transplanting Aman-Sunflower-Aus cropping pattern. Weed population and weed dry weight were significantly affected by crop residues treatment. Weed population was significantly lower in C3 (Direct sowing of Aus after 7 days of Sunflower residue incorporation) treatment than the control C1 (Direct sowing of Aus without Sunflower residue incorporation) treatment. The lowest weed dry weight (90.5 g m-2) was also obtained from C4 (Direct sowing of Aus after 14 days of Sunflower residue incorporation). The highest reduction of grain yield was obtained from without crop residue and no weeding treatments. The highest number of effective tillers m-2 (403.33), grain panicle-1 (114.67), tillers hill-1 (16.36), and grain yield (3.32 t ha-1) were observed from the treatments where sunflower residue was incorporated and the plots that were weed free. Results of this study indicate that sunflower residues showed potentiality to inhibit weed growth and it has a significant effect on the yield and yield parameters of direct seeded rice. Again weeds played a significant role in the reduction of yield of direct seeded rice. Thus, sunflower residues might be substitute for weed management practice as well as obtaining higher yield of direct seeded rice. Bangladesh Agron. J. 2021, 24(2): 115-125
在孟加拉国，直播水稻是一种传统的水稻种植方式，由于这一时期存在有利的环境，杂草侵扰是直播水稻生产中的一个严重问题。因此，通过最大限度地减少除草剂的使用，并用基于天然植物产品或化感物质的环保和环境可持续的除草剂取代它们，在孟加拉国水稻研究所（BRRI）的研究场地进行了一项基于随机完全区组设计的析因实验，共进行了三次重复，2018年7月至2019年8月，在孟加拉国，评估向日葵作物残留物对阿曼向日葵Aus种植模式下直接播种Aus水稻杂草生长和产量的影响。作物残留处理对杂草种群和杂草干重有显著影响。C3（向日葵残留物掺入7天后直接播种Aus）处理的杂草种群显著低于对照C1（不掺入向日葵残留物的直接播种Aus）处理。从C4（向日葵残留物掺入14天后直接播种Aus）也获得了最低的杂草干重（90.5gm-2）。无作物残留和无除草处理的粮食减产幅度最大。有效分蘖数m-2（403.33）、粒穗数-1（114.67）、分蘖丘数-1（16.36）和籽粒产量（3.32 t ha-1）在向日葵渣处理和无杂草处理中最高。研究结果表明，向日葵残基具有抑制杂草生长的潜力，对直播水稻的产量和产量参数有显著影响。杂草在直播水稻减产中再次发挥了重要作用。因此，向日葵残留物可以替代杂草管理实践，并获得更高的直播水稻产量。孟加拉国Agron。J.2021，24（2）：115-125

The production area of chickpea in Bangladesh is decreasing day by day due to the competition with higher yielding crop which is/or profitable than chickpea. As such, the experiment was undertaken at Regional Agricultural Research Station, Jashore during 2019-2020 and 2020-2021 to study the effect of most suitable method of de-topping (nipping) in chickpea (var. BARI Chola-10) for its growth and yield improvement. Treatments were imposed in a split-plot design where in main plot : time of nipping : 30 days after emergence (DAE) , 40 DAE E3- 50 DAE and in sub-plot: different heights of nipping practices: Control, Nipping 5 cm from growing tip, Nipping 8 cm from growing tip and Nipping 10 cm from growing tip. In interaction treatment, the highest days to flower (68), days to mature (112), vegetable yield (703 kg ha-1) was observed when chickpea plants were de-topped after 50 DAE at 10 cm from growing tip. The highest plant height (46 cm) was observed when de-topping at 40 DAE was done at 10 cm from growing tip. Seed yield (1419.95 kg ha-1) and Marginal Benefit Cost Ratio (MBCR) (13.1) was recorded maximum when chickpea plants de-topped 50 DAE at 5 cm from growing tip. De-topping practices in chickpea (var. BARI Chola-10) after 50 DAE at 5 cm from growing tip could maximize the productivity of chickpea. Bangladesh Agron. J. 2021, 24(2): 109-113

Soil salinity is a serious threat to crop productivity which influence growth and productivity of crop plants. Salt tolerance differ species to species and variety to variety. Therefore, this research work was initiated to investigate the influence of salinity levels on growth and yield of tomato genotypes and to select suitable variety for salt affected areas. A two factor poly house experiment was conducted in completely randomized design in Khulna University, Bangladesh, during November 2019 to March 2020. Factor one was consisted of fifteen tomato varieties including eight improved varieties developed by Bangladesh Agricultural Research Institute (BARI) and seven cultivars collected from farmer’s field of Khulna region. Other factor was consisted of five levels of soil salinity viz. control, 4, 8, 12 and 16 dSm−1. Tomato genotypes and salinity usages both significantly dissimilar for the agro- morphogenic traits. The plant height, leaf traits and yield traits are negatively influenced by salinity level. The local variety Guli gave the highest plant height for all the treatments. Tomato var. BARI tomato-15 produced the maximum fruit weight plant-1 at control followed by 4dSm-1 and 8 dSm-1. Therefore, tomato var. BARI tomato-15 may be suitable for cultivation in the areas containing salinity up to 8 dSm-1. This may also help to further improve tomato cultivars in saline areas. Bangladesh Agron.

The experiment was carried out at the Bangladesh Agricultural Research institute, Joydebpur, Gazipur during 2012 to evaluate the intercepted PAR in maize intercropped withlegumein comparison to monoculture for better weed suppression, productivity and economic benefits in kharif season. There were 17 treatments in the experiment viz., T1= Sole maize (no weeding), T2= Maize + Mungbean (no weeding), T3= Maize + Mungbean (weeding at 20 DAE), T4= Maize + Mungbean (weeding at 40 DAE), T5= Maize + Mungbean (weeding at 20 and 40 DAE), T6= Maize + Soybean (no weeding), T7= Maize + Soybean (weeding at 20 DAE), T8= Maize + Soybean (weeding at 40 DAE), T9= Maize + Soybean (weeding at 20 and 40 DAE), T10= Maize + Blackgram (no weeding), T11= Maize + Blackgram( weeding at 20 DAE), T12= Maize + Blackgram( weeding at 40 DAE), T13= Maize + Blackgram (weeding at 20 and 40 DAE) T14 =Sole maize (weed free), T15= Sole Mungbean (weed free), T16=Sole Soybean (weed free) and T17= Sole Blackgram (weed free).The results showed that PAR was significantly affected by cropping system, where it was higher in intercropping systems compared to sole crop . Regarding weed control, intercrops were more effective than sole crops and it was related to lower availability of PAR for weeds in intercropping systems. The highest grain yield (8.05 t ha-1). was obtained from weed free sole maize Among all intercropping, maize + mungbean along with two hand weeding gave the highest yield (maize: 7.18 t ha-1; 572.6 kg ha-1 mungbean), maize equivalent yield (MEY) = 12.49t ha-1and BCR = 2.84). From the study it can be concluded that maize mungbean intercropping with two hand weedings at 20 and 40 DAE would be the best in reducing weed growth, producing maximum yield and net return in intercropping systems under kharif season.

A field experiment was conducted at the Agronomy field, Sher-e-Bangla Agricultural University, Dhaka to evaluate the effect of water stress at reproductive stage on growth, grain development and yield of Boro rice. The experiment consisted of two factors: Factor A: Water stress viz. no water stress (W1) and water stress (W2) and Factor B: Variety viz. BRRI dhan28 (V1), BRRI dhan29 (V2), BRRI dhan50 (V3), Binadhan-10 (V4), BRRI hybriddhan3 (V5), Aloron (V6). In no water stress, irrigation water was maintained strictly from transplanting time to harvesting time while in water stress condition; supply of irrigation was stopped just after flowering upto harvest. Results showed that growth, grain development and yield of Boro rice were significantly affected by water stressed condition. All the tested varieties performed better under no water stress condition compared to water stress condition. About 7% panicle weight was decreased due to water stress condition at reproductive stage. Grain development of BRRI dhan29 was least affected by water stress while the most affected variety was Binadhan-10. Water deficit at reproductive stage reduced about 15-22% grain yield of tested varieties. Aloron was the least affected variety due to water stress while BRRI dhan50 was the most affected variety. The variety Aloron provided equal yield (7.31 t ha-1) under stress condition as given by BRRI dhan29 under no water stress condition. So, Aloron may be a better option to cultivate in the region where irrigation water is scarce or costly. Bangladesh Agron. J. 2021, 24(2): 99-107

A field trial on soil test based (STB) fertilizer doses was conducted during the year of 2017-2018 and 2018-2019 in Jashore region (AEZ-11) to find out the most suitable fertilizer doses for four crop based cropping pattern considering the agronomic feasibility and economic return of the system. The experiment consisted of eight different treatments viz. T1: 100% NPKSZnB (STB), T2: T1 + 25% N, T3: T1 + 25% NP, T4: T1 + 25% NK, T5:T1 + 25% PK, T6:T1 + 25% NPK, T7: 75% of T1, T8: Native fertility. Randomized complete block design (RCBD) with three replications was followed. Data revealed that seed yield of mustard was remarkably influenced by fertilizer treatments while grain yield of other components of the cropping system was not affected significantly by the treatments except control or native fertility. It was observed that 25% more NPK over 100% STB dose provided the highest yield of all the component crops. The highest rice equivalent yield (3.34 t ha-1) was recorded from T6 and the lowest (1.88 t ha-1) from T8 treatment. Maximum gross return (Tk. 420000/ha) and marginal benefit cost ratio (4.08) were also obtained from T6 treatment. So, 25% NPK+ 100% STB dose of fertilizer could be followed for productive and remunerative rice based cropping system Mustard-Boro-T. Aus-T.Aman in AEZ-11. Bangladesh Agron. J. 2021, 24(1): 109-117
