Aim: To identify the best planting time for obtaining higher seed yield and quality of Soybean in off season. Study Design: Randomized completely block design (RCBD) Place and Duration of Study: Agricultural Research Station, Halladkere, Bidar, Karnataka between 2016 and 2017. Methodology: A field experiment was conducted at Agricultural Research Station, Halladkere, Bidar to find out the best off season planting time for quality seed production of Soybean. The certified seeds of soybean varieties, JS-335 and Dsb-21 were sown with recommended package of practices at appropriate field condition from November to February at every fortnight with a spacing of 30 cm X 10 cm. The quality parameters related to seed were carried out in the laboratory of seed science department. Further, soybean seeds were treated with fungicide (carbendazim 25% + mancozeb 75%) at the rate of 3 gram per kg of seeds. Results: From the present investigation, it was observed that among the different sowing dates, soybean varieties (JS 335 and DSb 21) sown during 1st fortnight of November recorded significantly higher plant growth parameters as well as seed yield followed by 2nd fortnight of November during off season. Further, climatic factors like rainfall, maximum and minimum temperature and relative humidity played a major role in the off season to produce higher seed yield and quality of Soybean. Conclusion: Among various sowing dates, November 1st Fortnight sowing resulted in highest seed yield with better seed quality in both cultivars (JS-335 and Dsb-21) of soybean.

An experiment was conducted at Regional Agricultural Research Station, Jashore, Bangladesh during rabi season of (2019-2020) to evaluate the effect of foliar application of urea on growth and yield of short durative lentil variety (BARI Masur-9). The experiment was conducted in split plot design with three replications where time of urea spraying, P1= at branching stage, P2= at pod initiation stage were distributed in main plots and doses of urea spraying T1= application of 100% recommended fertilizers as basal except urea, T2= application of 100% recommended fertilizers as basal, T3= application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying, T4= application of 25% of urea with 100% of other fertilizers as basal and rest of the 75% of urea by spraying, T5= application of 50% of urea with 100% of other fertilizers as basal and rest of the 50% of urea by spraying were distributed in sub plots. The highest plant height, number of pods per plant were obtained from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea spraying at pod initiation stage. The highest seed yield was also found from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea spraying at pod initiation stage followed by application of 100% recommended fertilizers as basal and application of 50% of urea with 100% of other fertilizers as basal and rest of the 50% of urea by spraying at branching stage. Plant height, pods per plant and days to maturity showed positive correlation with seed yield. On the other hand days to flower and plants per m2 has no linear relationship with seed yield. The highest marginal benefit cost ratio (3.29) was recorded from application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying at pod initiation stage. So based on findings to increase the yield potential of BARI Masur-9 foliar application of urea may be a tool and hence application of 75% of urea with 100% of other fertilizers as basal and rest of the 25% of urea by spraying at pod initiation stage may be consider as the best treatment.

A field experiment on okra cv. BARI Dherosh–1 comprising four sowing times starting from February to May (15th day of each month) at monthly interval and four spacings (60 × 30, 60 × 40, 60 × 50, and 60 × 60 cm) was conducted at the Agricultural Research Station (ARS), Raikhali, Rangamati Hill District to find out the most suitable sowing time and optimum plant spacing for the two consecutive years of 1997 and 1998. The highest seed yield (2.97 t/ha) was recorded from 15 April sowing closely followed by 15 March sowing (2.77 t/ha) whereas the best quality seed was obtained from 16 February (88.7% germination and 29.75 seed vigour index) and 15 March (83.7% germination and 28.80 seed vigour index) sowing. Plant spacing of 60 × 40 cm produced the highest seed yield of okra (2.86 t/ha) followed by 60 × 30 cm spacing (2.80 t/ha). The germination percentage and seed vigour index were unaffected due to different plant spacings. 15 April sowing accompanied with 60 × 30 cm spacing gave the highest seed yield (3.13 t/ha) closely followed by 60 × 30 cm spacing with the same sowing time (3.06 t/ha). The seed yield did not decline in 15 March sowing having similar spacings.DOI: http://dx.doi.org/10.3329/bjar.v32i3.541Bangladesh J. Agril. Res. 32(3) : 393-402, September 2007

Performance of ‘Bilati Dhonia’ (Eryngium foetidum L.) grown under the shades of different tree species, namely guava, jackfruit, mango, jujube, and farmers’ practice (grown under artificial shade) was evaluated at the Agricultural Research Station, Raikhali, Rangainati Hill District during two consecutive years of 2004-05 and 2005-06. The results revealed that plant height, leaf length, number of leaves per plant and fresh weight per plant were significantly higher under the canopies of various trees and farmers’ practice than those grown under direct sun light. Different growth characters were better under the shades of jackfruit and guava trees than those of other species. Periods to first and 50% flowering under tree species were longer than that under direct sunlight. The highest fresh yield (mean of two years) of ‘Bilati Dhonia’ was found in the farmers’ practice (27.58 t/ha), which was similar to those under guava (27.31 t/ha) and jackfruit trees (27.51 t/ha).

Yield and quality performances of three jackfruit genotypes were studied at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Pahartali, Chittagong during 2013-2014. Age, growth, maturity period, yield potential and also qualitative characteristics were compared among them.  Based on overall performance with respect to bearing potential, maturity period, fruit and bulb characters, the genotypes AHPah-1 have been found promising for table purpose followed by AHPah-2 and AHPah-3. Minimum days (117) to 1st harvest were observed in AHPah-1. The number of fruits per plant was exceedingly higher (73) in AHPah-1 whereas minimum number (41) was found in AHPah-2. Maximum weight (8.40 kg) per fruit was observed in AHPah-2 and minimum was in AHPah-1(3.40 kg).  The highest single fruit length (37.25cm) was found in AHPah-2 and breadth (27.00cm) was produced by AHPah-3. Maximum number of bulbs (116) was produced in AHPah-1, whereas minimum (63.00) was in AHPah-3. Maximum weight of bulbs per fruit (4.24 kg) was produced in AHPah-2. Individual bulb weight was higher (54.42g) in AHPah -2 whereas, the lowest (16.71) was in AHPah-1. Edible portion was higher (69.27%) in AHPah-1 whereas, the lowest (53.43%) was in AHPah-3. The TSS was the highest (21.00%) in AHPah-1. The highest bulb length and breadth was found in AHPah-3. Highest seeds weight (639g) was produced in AHPah-2. Individual seed weight (8.19 g) was higher in AHPah-2. Therefore, the genotypes can be included in the variety development program after comparing with the already BARI released jackfruit variety.The Agriculturists 2016; 14(1) 107-111

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.

Preharvest applications of glyphosate have been shown to be effective in controlling Canada thistle in annual crops, but may reduce alfalfa seed yield depending on time and rate of application. The objective of this study was to determine the effect of preharvest applications of glyphosate on subsequent alfalfa seed yield and quality. The effects of timing, 1, 26, 51 and 76% alfalfa seed pod maturity, and rate, 0, 440, 880, 1320, and 1760 g a.i. ha-1, of a preharvest application of glyphosate on alfalfa seed yield and quality in the year of application, and regrowth and seed yield in the following year were determined. The rate of glyphosate applied did not affect seed yield in the application year; however, in the following year, growth and seed yield were reduced as rates increased. Delaying the application of glyphosate increased seed yields in the application year, but decreased alfalfa regrowth and flowering the following year. Germination and seedling emergence were not affected by the rate or timing of the glyphosate. A preharvest application of glyphosate at 1760 g a.i. ha-1 at 76% pod maturity is a viable option in the last year of seed production.

Background: Mungbean is a short duration grain legume widely grown in south and Southeast Asia. The extent of variability through Principal Component Analysis (PCA) and cluster analysis in promising mungbean genotypes should be known for possible yield improvement. A study was undertaken to work out the extent of variability among twenty four mungbean genotypes through cluster analysis and Principal Component Analysis (PCA). Methods: The experiment was laid out in a randomized block design with three replications during kharif 2018 and 2019 at the experimental field of Agricultural Research Station, Navgaon (Alwar) under rainfed condition. Result: Principal component analysis revealed that the first three main PCAs amounted 78.80% of the total variation among genotypes for different traits. Out of total principal components, PC1 accounts for maximum variability in the data with respect to succeeding components. Number of branches per plant (28.62%), number of clusters per plant (23.55%) and seed yield (15.58%) showed maximum per cent contribution towards total genetic divergence on pooled basis. Cluster analysis showed that genotypes fall into seven different clusters and their inter and intra cluster distance showed genetic diversity between different genotypes. The maximum number of genotypes i.e., 8 was found in cluster II followed by cluster III comprising of 6 genotypes. Genotypes RMG-1138 and IPM-02-03 representing the mono genotypic cluster signifies that it can be the most diverse variety and it would be the appropriate genotype for hybridization with ones present in other clusters to tailor the agriculturally important traits and ultimately to boost the seed yield in mungbean under rainfed conditions.
