Abstract In South Asia, including Bangladesh, most farmers sow wheat under residual soil moisture after rice is harvested, but the upper layer of soil dries quickly after soil has been prepared for wheat sowing. Crop seeds that are sown either deeply or shallowly can result in failed emergence, low dry matter accumulation, and reduced grain yield. Therefore, appropriate sowing depth is crucial for seedling emergence and successful crop establishment. Considering this, a two-year field experiment was conducted at the research field of the Agricultural Research Station of the Bangladesh Agricultural Research Institute at Dinajpur during the dry, rabi (winter) season of 2013-14 and 2014-15, at four sowing depths, i.e., 2, 4, 6 and 8 cm, to identify the most appropriate sowing depth for higher grain yield. Wheat seeds sown at a depth of 4 cm resulted in significantly highest number of seedlings and seminal roots, tallest plants as well as largest roots and plant biomass followed by sowing at a depth of 6, or 2 cm. Depth of sowing also significantly affected the yield and yield-related attributes, all performing best at a depth of 4 cm. The highest number of spikes m-2, grain yield, straw yield and harvest index were observed when seeds were sown at depths of 4 or 6 cm, relative to 2 or 8 cm. Therefore, a sowing depth of 4 to 6 cm is recommended for wheat cultivation in South Asia, including Northern Bangladesh.

Chickpea is one of the important winter legumes in Nepal. It is grown after rice or maize either as sole or mixed crop. In Nepal, chickpea is mostly grown as rainfed crop on residual soil moisture or sometimes under irrigation. Lack of irrigation results drought and heat stress which affects crop growth and development. Irrigation at proper time is one of the most important factors for achieving higher crop yield.  The experiment regarding use of supplementary irrigation time on chickpea was carried out at Regional Agricultural Research Station, Khajura, Banke, Nepal during the winter season of the year 2011 and 2012. The experiment was laid out in Randomized Complete Block Design with three replications. Seven different time intervals of irrigation was applied in the experiment for both years. Treatments differed significantly in terms of grain yield but showed non -significant difference in days to flowering and maturity over the years. The combined analysis of the experiments showed that the highest grain yield (2318 kg/ha) was produced when irrigation was supplied at vegetative stage followed by irrigation supplied at flowering stage (2298 kg/ha) and pod fill stage (2104 kg/ha) respectively.Int J Appl Sci Biotechnol, Vol 3(3): 431-433

Field experiments were conducted at the Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jessore during rabi (winter) seasons of 1999-2001 to study the tillage and mulching effects on conservation of residual soil moisture, yield attributes and yield of mustard (cv. Daulat.). Three different tillage methods, namely minimum, reduced and conventional tillage were used in the main plots and three different mulch materials, namely rice straw, water hyacinth, black polythene including no mulch were used in the sup-plots. It was observed that reduced tillage and polythene mulch or rice straw mulch conserve more moisture than other tillage methods and mulch application. Tillage practice significantly influenced the dry matter, yield and yield components of mustard. Reduced tillage gave consistently the highest seed yield (969 kg/ha), while minimum tillage gave the lowest seed yield (92 kg/ha). Mulching also resulted in better crop growth and increased yield. Significantly higher seed yield (1164 kg/ha) was recorded from black polythene mulch followed by rice straw mulch (1089 kg/ha). The yield of mustard was obtained due to the interaction effects on reduced tillage and polythene mulch followed by conventional tillage and polythene mulch, which was found superior to all other treatments. Results revealed that polythene mulch or rice straw mulch accompanied by reduced tillage was economically profitable for mustard cultivation/production under rainfed condition. Key Words: Rainfed mustard, tillage, mulching. doi: 10.3329/bjar.v33i4.2303 Bangladesh J. Agril. Res. 33(4) : 597-606, December 2008

Background: Blackgram is an important crop among kharif pulses and is usually grown on marginal and sub-marginal lands without proper weed management under rainfed situation. Broad bed furrows had greater influence on plant growth over farmers practice. Weed management through mechanical or manual is normally tedious, labour consuming and costlier. Keeping this in view, the present study was envisaged to investigate integrated effect of land configuration and weed management regimes on productivity of urdbean. Methods: A field experiment was carried out during kharif seasons of 2016 and 2017 at Regional Agricultural Research Station, Lam, Guntur on effect of land configuration and weed management on performance of urdbean (Vigna mungo L.Hepper). The treatments included two land configurations i.e., flat bed and broad bed furrow method allotted as horizontal plots and four weed management practices i.e., weedy check, pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE, imazethapyr 10% SL @ 55 g ha-1 at 15-20 DAS and pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS allotted as vertical plots replicated four times in a strip plot design. The comparison of treatment means was made by critical difference (CD) at P less than 0.05 by using standard statistical procedures. Result: Based on the results, it can be concluded broad bed method of land configuration proved its superiority over flat bed method by producing 12.8 per cent higher grain yield besides empowering growth and yield attributes. Among the weed management practices, the highest grain yield (1280 kg ha-1) recorded with pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS along with maximum monetary returns and B:C can be recommended for urdbean.

A field experiment was conducted for two consecutive Kharif seasons of 2012-13 and 2013-14 in a Split Plot Design with three replications, at Agricultural Research Station, Seethampeta, Andhra Prtadesh, India to generate scientific data on organic farming, integrated nutrient and pest management practices, chemical farming with four prominent varieties of rice viz., MTU 1001, RGL 2538, BPT 5204 and MTU 7029 in high altitude and tribal areas of Andhra Pradesh. Results showed that, grain yield of rice was reduced in organic farming by 37 per cent and 30.23 per cent compared to chemical farming and INM practices. Growth, yield attributes of rice also reduced noticeably in organic farming. Whereas, organic farming recorded higher root biomass per hill at flowering, higher post nutrient status of available nitrogen, phosphorus and potassium and lesser incidence of diseases and pests over INM and chemical farming. Chemical farming recorded higher growth, yield attributes, yield and returns. Among the cultivars, MTU 1001 showed better performance and recorded the higher grain yield and straw yields and least affected by diseases and pests compared to other varieties.

Field experiments were conducted during kharif 2013 and 2014 at Agricultural Research Station, Mugad, University of Agricultural Sciences (UAS), Dharwad (Karnataka), to determine the response of zinc applicationon on growth, zinc content and grain yield of rice genotypes and also studied correlation between yield and zinc content. The experiment was comprised of 20 genotypes and three treatments viz., T1: Control (no zinc); T2: Soil application of ZnSO4 (20 kg ha-1) T3– Foliar Spray of ZnSO4 @ 0.5% at 50% flowering, laid out in factorial randomized block design with two replications. The data revealed that application of ZnSO4 recorded significantly higher plant height (85.9 cm), leaf area (764.5 cm-2 plant-1), number of tillers (95.4 m-1), total dry weight (26.1 g plant-1), panicle weight(15.3 g plant-1), number of panicles (81.6 m-1) and grain yield(3966 kg ha-1) over the foliar application of Zn and control . However number of grains panicle-1 (97.8 panicle-1), test weight (23.7 g), shoot and seed zinc content (15.9 and 21.2 ppm, respectively) were increased with foliar application of Zn. Correlation studies classified the genotypes as high seed zinc content (> 21 ppm) and low seed zinc content genotypes ( less than 21 ppm). High and low seed zinc content genotypes showed negative correlation with yield and yield attributes. However, shoot zinc content was positively correlated with yield.

Aims: To find a suitable alternate option of nutrient management in organic mungbean with standardization of dose and its mode of application. Place and Duration of Study: Agricultural Research Station, Mandor, Jodhpur between July 2020 and October, 2020. Methodology: Treatment comprised of main plots as mode of application: M1: Soil application, M2: Foliar application and M3: Soil and foliar application and sub plots as dose of Jiwamrita: S1: Control, S2: 50 ml/l, S3: 100 ml/l and S4: 150 ml/l were replicated thrice in split plot design. FYM @ 5.0 t/ha was applied on the soil and the field of the experimental site was prepared by disking following harrowing and planking. The crop variety GM 6 was sown on 10th July, 2020 at row spacing of 30 cm with seed rate of 15 kg/ha. The plants were kept at 10 cm distance after thinning at 15 days after sowing. Jiwamrita was prepared using Palekar [1] method (Photo 1) and was kept in shade for 7 days. It was filtered before using for spray as per treatments. It was applied as soil spray at the time of sowing and 15 days after sowing as per treatments of different doses. Foliar application of Jiwamrita was done at 15 and 30 days after sowing as per treatments. Total quantity of solution containing Jiwamrita was 500 liter/ha in all the treated plots. In control plots, a quantity of 500 liter/ha was used as spray. Weeding was done manually at 15 and 30 days after sowing. Data on growth attributes, yield attributes and grain yield was recorded from net plot size of 4 m x 1.8 m and converted into hectare basis. The gross return was computed by multiplying current price of mungbean with yield. The net return was estimated by deducting cost of cultivation from gross return. The benefit-cost ratio was worked out by dividing gross return by cost of cultivation. Results: Maximum plant height of 71.5 cm was recorded with a dose of Jiwamrita @ 150 ml/liter which was at par with Jiwamrita @ 100 ml/liter. The SPAD chlorophyll meter reading (SCMR) of leaves increased at 50 DAS (53.5) being maximum with Jiwamrita @ 150 ml/liter which was significantly higher over SCMR recorded with Jiwamrita @ 50 ml/liter (34.7). The significantly maximum number of pods/plant (28.7) and maximum grain yield (1314 kg/ha) was recorded due to combined application of soil and foliar application of Jiwamrita. Among doses, maximum number of pods (30.9) was recorded under Jiwamrita @ 150 ml/liter which was 30, 24 and 16 percent higher over control and Jiwamrita @ 50, 100 ml/liter. The application of Jiwamrita @ 150 ml/liter resulted in significantly higher grain yield (1221 kg/ha) which was found at par with Jiwamrita @ 100 ml/liter (1179 kg/ha) which were 17 and 13 percent higher, respectively, over control and 9 and 5.6 percent higher, respectively, over Jiwamrita @ 50 ml/liter. The maximum net return ( 65672 ha-1) was recorded with 150 ml/liter followed by 100 ml/liter ( 62686 ha-1). Conclusion: Jiwamrita is a fermented microbial culture which provides essential nutrients to plants. Its application in both soil and plant canopy were found beneficial. The study revealed that twice application of Jiwamrita in soil at the time of sowing and 15 days after sowing and twice application of Jiwamrita as foliar spray at 15 and 30 days after sowing significantly increased the growth attributes, yield attributes and yield of organic mungbean.

The aim of this study was to identify stable and high yielding genotypes under various environments and years in different hilly regions of Nepal. Five finger millet genotypes along with farmer’s variety (Local check) were tested under command areas of five different stations namely, Hill Crops Research Program (HCRP), Dolakha, National Ginger Research Program (NGRP), Salyan, Agricultural Research Station (ARS), Dailekh, ARS, Surkhet and Regional Agricultural Research Station (RARS), Kaski during 2016 and 2017 winter season under rainfed condition. The experiment was conducted using Randomized Complete Block Design with two replications under farmer’s field condition. The genotype x environment (GxE) interaction for grain yield was significant. The genotypes KLE-236 (2.37 t/ha), KLE-158 (2.32 t/ha) and DR-2 (2.02 t/ha) were found higher sensitive to environment and produced the higher mean grain yield across the locations. Joint regression analysis showed that genotypes KLE-236, KLE-158 and DR-2 with regression coefficient of 1.15, 1.17 and 1.12 respectively. The coefficient of determination (R) for genotypes, KLE-236, KLE-158 and DR-2 were high as 0.6, confirming their high predictability for the stability across the different locations. Further confirmation from GGE biplot analysis showed that stable genotype KLE-236, KLE-158 and DR-2 were more stable and adaptive genotypes across the tested environments of Dailekh, Surkhet, Salyan and Dolakha respectively. Thus these genotypes could be recommended to farmers for general cultivation across the tested environments.

The aim of present investigation was to study the effect of foliar application of gibberellic acid (Progibb 40% WSG) spraying at 4-5 leaves stage of the maize crop. Two field experiments were conducted during kharif 2014 and rabi 2014-15 at Research Farm, Zonal Agricultural Research Station, Jhabua. Seven treatments (T = 20, T 30, T 40, T 50 T 60 gibberellic acid g/ha, Tricontanol 1 2= 3= 4 = 5= 0.1%= 250 ml/ha and control) were tested in randomized block design with three replications. Results showed that variation in different doses of gibberellic acid had significant effect on growth character (plant height and silking) and yield attributes (no. of cobs/plant, cob length, no. of grains/cob and cob weight/cob); grain yield and stover yield of maize in both the seasons. Higher values of plant height (197.33 and 205.5 cm) and silking (53.67 and 54.67) was recorded with the spraying of gibberellic acid @ 60 g/ha in both the seasons, respectively. Similarly the higher yield attributes viz., no. of cobs/plant (1.48 and 1.49), cob length (17.40 and 17.78 cm), no. of grains/cob (443.33 and 456.67) and cob weight/cob (93.2 and 97.32) were recorded with the application of gibberellic acid @ 50 g/ha in both the seasons, respectively. Application of gibberellic acid @ 50 g/ha produced highest grain yield (3522 and 4277 kg/ha) and stover yield (51.05 and 5413 kg/ha) which was statistically at par with doses of 40 g/ha, 60 g/ha and tricontanol 0.1% @ 250 ml. The maximum gross return (Rs. 56,347 and 65,854), net return (37,722 and 47,229), B: C ratio (3.03 and 3.54), production efficiency (32.49 and 37.19 kg/ha/day) and economic efficiency (339.84 and 410.69 Rs./ha/day) recorded with gibberellic acid @ 50 g/ha. Enhancing of production, productivity and profitability of maize under Jhabua Hill of Madhya Pradesh gibberellic acid applied @ 50 g/ha at 4-5 leaf stage of crop.
