The experiment was conducted in two consecutive crop seasons (2015-16 and 2016-17) at Regional Agricultural Research Station (RARS), Hathazari, Chattogram during Rabi season (November to March) with 3 duplicate laid out Randomized Complete Block Design (RCBD) to compare the rehearsal of high-placed outcome, early maturing and heat tolerant varieties under increasing temperature. BARI released early maturing wheat varieties were used for optimum sowing time and heat tolerance as an adaptive mechanism suffering from terminal heat stress. Six heat-tolerant early maturing wheat varieties were (BARI Gom 25, BARI Gom 26, BARI Gom 27, BARI Gom 28, BARI Gom 29, and BARI Gom 30). The highest crop output was gained from BARI Gom 30 (4.33 t/ha) followed by BARI Gom 26 (4.06 t/ha) in a couple of years. The lowest yield was found from BARI Gom 27 (2.66t/ha) followed by BARI Gom 29 (3.53 t/ha), BARI Gom 28 (3.36 t/ha), and BARI Gom 25 (3.13 t/ha) both years. Crop output of wheat and amount of spike showed significant difference and rest of the parameters were insignificant. The earliest maturing variety was BARI Gom 30 and produced a maximum crop yield than others. BARI Gom 30 showed a maximum benefit-cost ratio (BCR) of 1.73 and BARI Gom 27exhibited the lowest benefit-cost ratio (BCR) of 1.06. This result of the experiment showed that early high yielding variety and the best adaptive variety was BARI Gom 30 among the six varieties in Chattogram.

A field experiment was carried out during 2015-16 and 2016-17 at ICAR-Central Potato Research Station, Patna, Bihar, in randomized block design with four replications with objective to quantity the optimum requirement of nitrogen to potato crop. Significantly the highest plant height was recorded with nitrogen level of 300 kg/ha. Distributions of the smallest size of tuber yield of potato were decreasing with increasing the level of nitrogen. There was about 26.0% more yield of the smallest size tuber of potato was recorded with zero nitrogen as compare to the highest level of nitrogen i.e. 300 kg/ha. Increasing the nitrogen over the level of 150 to 225 kg per hectare, increasing the yield of tuber gradually slower rate than nitrogen level from 0 to 150 kg/ha. Total and marketable tuber yield of potato were increasing significantly with increasing level of nitrogen up to 150 kg/ha. There was no significant difference in marketable tuber yield was found for nitrogen level between 150 and 225 kg/ha. Highest (1.66) net benefit cost ratio was also recorded with level of nitrogen @ 150 kg/ha in potato. Hence, application of nitrogen @ 150 kg/ha was found statistically and economically more beneficial for potato cultivation in Eastern Indo-Gangatic plain of India.

A study on comparative productive efficiency and feasibility of lentil varieties both at relay and minimum tillage were conducted at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh during the Rabi season of 2007-08 and 2008-09. Three lentil varieties viz. BARI Masur-2, BARI Masur-3 and BARI Masur-4 and two sowing methods viz. relay sowing and furrow sowing (Minimum tillage) were compared. The highest seed yield (1.59 t/ha) was obtained from BARI Masur-4 because of highest number of pods/plant and plant population/m2 while lowest from BARI Masur-2 (1.39 t/ha). The sowing methods had significant effect on the seed yield of lentil. Crops sown in furrows produced higher seed yield (1.60 t/ha) than that of crops in relay sowing. The interaction effect between varieties and sowing methods also had significant effect on the seed yield and yield attributes. The lentil variety BARI Masur-4 when grown in furrows gave the highest seed yield (1.70 t/ha). Though seed yield and gross return were highest in furrow sowing but highest benefit cost ratio (4.67) was found in relay sowing method.Bangladesh J. Agril. Res. 40(2): 271-278 June 2015

A field experiment on intercropping of okra and leafy vegetables was conducted at Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur and Agricultural Research Station, Burirhat, Rangpur during Kharif-I season of 2010 and 2011 to find out suitable crop combination for higher productivity and economic return. Seven treatments viz., sole okra (50 cm × 40cm), okra 100% (in row) + red-amaranth 100% (broadcast), okra 100% (in row) + red-amaranth 75% (broadcast), okra 100% (in row) + leaf amaranth 100% (broadcast), okra 100% (in row) + leaf amaranth 75% (broadcast), okra 100% (in row) + jute as patshak 100% (broadcast), okra 100% (in row) + jute as patshak 75% (broadcast) were used. Intercropping reduced okra yield but total productivity increased due to additional yield of vegetables. In both the locations, sole okra produced the highest yields (15.82 t/ha at Joydebpur and 13.79 t/ha at Burirhat). Among the intercropping treatments, the highest okra yields (15.42 t/ha at Joydebpur and 12.64 t/ha at Burirhat) were obtained from okra 100%+ red amaranth 75% combination. The lowest okra yield (13.16 t/ha at Joydebpur and 11.75 t/ha at Burirhat) was recorded in okra 100% + jute as patshak 100% combination. The highest okra equivalent yield (23.00 t/ha) was recorded in okra 100% + red amaranth 100% at Joydebpur and in okra 100% + leaf amaranth 100% (21.79 t/ha) at Burirhat. These treatment combinations also gave the highest gross margin (Tk. 227180/ha at Joydebpur and Tk. 214600/ha at Burirhat) and benefit cost ratio (5.66 at Joydebpur and 5.58 at Burirhat). The results revealed that cent percent red amaranth (broadcast) or leaf amaranth intercropped with cent percent okra might be suitable combination for higher productivity and economic return at Joydebpur and Burirhat, respectively.

A field experiment was carried out to study the “Effects of different maize–soybean intercropping patterns on yield attributes, yield and B: C ratio” at the Agricultural Research Farm, Bhagwant University, Ajmer. Treatment consists of Sole maize (60x20 cm), Sole Soyabean (30x10 cm), Maize-Soybean (1:1) (60X20 cm), Maize-Soybean (1:1) (75X20 cm), Maize-Soybean (1:1) (90X20 cm), Maize-Soybean (1:2) (90X20 cm) and Maize-Soybean (2:6) (Paired row 45/180 cm). There were four replicated blocks and plot sizes measuring 7 m x 4.5 m laid out in a randomized complete block design (RCBD). Results of the experiment showed that the maize-soybean intercropping patterns had significant effect on maize stover and grain yields. Sole maize recorded significantly higher yield than intercropped maize under varying geometry and row proportion. However, it was at par with maize intercropped with soybean in 1:1 row proportion with 60 x 20 cm .The intercropping patterns affected significantly the PAR intercepted and the leaf area index. The soybean sole crop intercepted significantly more light and leaf area index (LAI) than all other treatments and/or crop. Further,, the yield of sole soybean was significantly superior over other intercropped treatments. The highest benefit cost ratio revealed that higher return per unit money invested for inputs used for raising crops. The highest B: C ratio was recorded with maize + soybean in 2:6 paired row (3.57) intercropping system. The least B: C ratio was recorded in sole soybean (2.45).

The experiment was conducted at the farmer`s field of Boyerchor, Hatia, Noakhali under On-Farm Research Division, Bangladesh Agricultural Research Institute (BARI), during the rabi seasons of 2011-2013 to study the effect of variety on the productivity of fenugreek in coastal saline soil. The experimental treatments included 3 varieties viz. V1= BARI Methi 1, V2 = BARI Methi 2, V3 = Local Methi. The experiment was laid out in a randomized complete block design with six dispersed replications. There was a strong varietal influence on crop growth and seed yield. Among the varieties, BARI Methi 2 showed the best results in terms of plant height, number of branches, number of pods and number of seeds pod-1 resulting in the highest seed yield of 1497 kg ha-1. It was also observed that plant mortality of fenugreek was highly affected at germination stage when the soil salinity was above 4 dSm-1. However, at the later stages of crop growth up to the maturity, the salt tolerance of the crop was higher varying from 4-12 dSm-1. It was indicated that critical range of salinity level for cultivation of fenugreek was 3.42-12.2 dSm-1 from germination till to maturity. Among the fenugreek varieties, BARI Methi 2 offered the highest net return of Tk. 50150 coupled with a benefit cost ratio of 3.03. Though total cost was the same, BARI Methi 2 showed higher BCR (3.03) over BARI Methi 1 and local Methi due to yield differences. The Agriculturists 2014; 12(2) 18-23

Sugarcane is an important cash-cum-industrial crop of Bangladesh and mainly cultivated in north-western part of the country where different intercropping systems are available. The experiment was carried out at the Bangladesh Sugarcane Research Institute (BSRI) farm, Ishurdi, Pabna, Bangladesh in two successive years viz. 2008–2009 and 2009–2010 to investigate the profitability of sugarcane (cv. Isd 37) with potato (cv. Cardinal) and mungbean (cv. BINA mung5) as successive intercrops. Two factors included in the experiment viz. Factor A: Row to row distance of sugarcane such as 80 cm (S1), 100 cm (S2) and 120 cm (S3) where potato and Mungbean were intercropped. Factor B: Cutting of sugarcane leaf such as cutting of leaves (C1) and No cutting of leaves (C2). The experiment was laid out following randomize complete block design. For sugarcane cultivation BSRI technique and for intercropping the cultivation systems indicated by Bangladesh Agricultural Research Institute were followed. The cane yield and sugar yield were the highest at 100 cm row to row spacing (RRS) of sugarcane (non-leaf cutting = C0) intercropped with 2 rows (2R) of potato followed by 2R of mungbean (S2C0). The lowest yield of sugarcane was found at 80 RRS (C0) with one row (1R) of potato and 1R of mungbean (S1C0). The effect of light interception on growth and yield of first intercrop (potato) was insignificant but significant for second intercrop. The highest yield of potato tuber was 15.28 t ha–1 in S5 (sole potato) followed by 10.85 t ha–1 in S3C1 (sugarcane under leaf cutting at RRS 120 cm with 3R of potato followed by 3R of mungbean). For the yield of mungbean (2nd intercrop), light interception ratio (%) was significantly lowest in (S3C1) where sugarcane RRS was 120 cm with 3R of potato followed by 3R of mungbean under leaf non-cutting (C0) of sugarcane. The highest adjusted cane yield (170.66 t ha–1), benefit cost ratio (3.49) and LER (2.33) were observed in sugarcane at RRS 120 cm with 3R of potato followed by 3R of mungbean (S3C1). Results of both years indicated that intercrops gave higher land equivalent ratio and net return over sole sugarcane planted while sole sugarcane gave maximum benefit cost ratio compared with other intercrops. Finally, on the basis of results it may be concluded that sugarcane transplanted at RRS at 120 cm with 3R potato followed by 3R of mungbean can be grown as intercrops for higher economic return. J. Bangladesh Agril. Univ. 16(3): 429–436, December 2018
