The experiment was conducted at Agronomy Research Field, Bangladesh Agricultural Research Institute, Gazipur during 2010-11 to find out the appropriate planting system of potato and plant density of maize in potatohybrid maize intercropping system for maximum yield and economic return. Ten treatments were evaluated viz., T1= Potato whole tuber single row (75 cm × 20 cm) + 125% hybrid maize (75 cm × 20 cm), T2=Potato whole tuber single row (75 cm × 20 cm) + 100% hybrid maize (75cm × 25 cm), T3= Potato whole tuber single row (75 cm × 20 cm) + 83% hybrid maize (75 cm × 30 cm), T4= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) + 125% hybrid maize (75 cm × 20 cm), T5= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) +100% hybrid maize (75 cm × 25 cm), T6= Potato half tuber paired row (20 cm/ 55 cm × 20 cm) + 83% hybrid maize (75 cm × 30 cm), T7= Sole potato whole tuber single row planting system (60 cm × 25 cm), T8 = Sole potato half tuber paired row (20 cm/ 55 cm × 20 cm), T9= Sole hybrid maize in normal spacing 75 cm × 25 cm (sole HM1) and T10= Sole hybrid maize (75 cm × 25 cm) sown 30 days after potato planting (sole HM2). The results revealed that sole planting of both potato and maize produced the maximum yields. In case of sole potato, potato half tuber paired row planting system was better than potato whole tuber single row planting system. On the other hand, the performance of sole HM1 was better than sole HM2 in relation to growth, yield and economic performance. Over all T1 treatment ( potato whole tuber single row planting system with 125 % hybrid maize population) was the best intercropping system for getting higher yield and economic return as well as less relative crowding coefficient with better crop performance ratio.Bangladesh J.

Abstract. The adoption of Conservation agriculture (CA) contributes to sustainable production and its advantages include lower inputs and stable yields. This study was conducted in the research field of Regional Agricultural Research Station, Bhagetada, Dipayal, Doti during 2014 and 2015 to identify the effect of CA on grain yield and income of maize in Maize based cropping system. Both conservation and conventional agricultural (ConvA) practices were evaluated on two maize based cropping systems namely maize-wheat-mungbean (M-W-MB) and maize-lentil-mungbean (M-L-MB). For this purpose two maize varieties namely Raj Kumar and Arun-2 were used. The average productivity of maize under M-L-MB cropping system was 1.6% higher (5.75 t/ha) than M-W-MB cropping system (5.66 t/ha). The average grain yield of maize under CA was 16.7% higher (6.15 t/ha) than ConvA (5.27 t/ha). Rajkumar produced 43% higher average grain yield (6.73 t/ha) than Arun-2 variety (4.69 t/ha). The average net benefit was slightly higher (US$ 597.33/ha) under M-L-MB cropping system than M-W-MB cropping system (US$ 573.89/ha). Similarly, the average net benefit from CA was 102% higher (US$ 783.67/ha) than ConvA (US$ 386.79/ha). Rajkumar variety gave 127% higher average net benefit (US$ 813.49/ha) than Arun-2 (US$ 357.81/ha). The average benefit - cost (B:C) ratio of M-L-MB cropping system was slightly higher (1.72) than the average B:C ratio of M-W-MB cropping system (1.70). The average B:C ratio of CA was 42% higher (2.01) than ConvA (1.41). The average B:C ratio of Rajkumar variety was found 33% higher (1.95) than Arun-2 (1.46). The higher grain yield, net profit and B:C ratio were found in CA practices under M-L-MB cropping system and Rajkumar variety. This study suggests that hybrid maize planting and the adoption of M-L-MB cropping system should be used to increase grain yield and economic performance under CA practices.

The experiment was carried out at the research field of Agricultural Research Station, Rajbari, Dinajpur (Latitude: 25.63544, Longitude: 88.65144) during rabi season of 2016-2017 and 2017-18 under AEZ-1 to find out the suitable crop combination for higher productivity and economic return. Five different treatments were employed in the study viz. T1= Sole maize (60cm x×20cm), T2= Maize planting (75cm×x 25cm) + 1 row cabbage (50cm×50cm) T3= Maize paired row (150cm/37.5cm x 25cm) + 2 rows cabbage (50cm x×50cm) T4=Maize planting (60cm x×20cm )+1 row cabbage (60cm x×50cm), T5= Maize paired row (120cm/30cm× x 20cm) + 2 rows cabbage (60cm x 50cm) were evaluated. Maize grain yield in intercropped combination varied from 6.60-9.23 t ha-1. But the highest maize yield was recorded in Maize planting (60cm x 20cm) + 1 row cabbage (60cm x 50cm) followed by that in maize paired row (150/37.5cm × 25cm) +2 rows cabbage (50cm x×50cm), while the highest cabbage yield was recorded in maize planting (60cm x 20cm) + 1 row cabbage(60cm x 50cm) between maize. The highest maize equivalent yield was also obtained in maize planting (60cm x 20cm) + 1 row cabbage (60cm x 50cm) followed by that in maize paired row (150/37.5cm x 25cm) + 2 rows cabbage (50cm x 50cm). The highest gross return, gross margin and BCR were obtained in maize planting (60cm × 20cm) + 1 row cabbage (60cm x 50cm) followed by that in maize paired row (150/37.5cm x 25cm) +2 rows cabbage(50cm x 50cm) and the lowest in sole sowing of maize. The overall results indicated that among the intercrop combinations maize planting (60cm x 20cm) + 1 row cabbage (60cm x 50cm) and maize paired row (150/37.5cm x 25cm) +2 rows cabbage (50cm x 50cm) were found suitable for total productivity and economic return of the system.

An experiment was conducted at Agronomy Research Field of Bangladesh Agricultural Research Institute, Gazipur for five consecutive years (2014-2015 to 2018-2019) to establish a functional relationship between grain yield and spikes/m2 of wheat at late sown condition. Variation of spikes/m2 was created by five seed rates (90, 120, 150, 180  and 210 kg/ha). Pooled average value of spikes / m2 was observed the highest (479-506) in 180-210 kg seed /ha. From the structural treatment, the highest grain yield (pooled average of 3876-4153 kg/ha ranged 3295-5028 kg/ha) of wheat was produced in the seed rate of 150-180 kg/ha. The estimated optimum seed rate was found 162.29 kg/ha with the estimated grain yield 3989 kg/ha of wheat at late sown condition through the developed function model of Y=485.91+43.17X-0.133X2 (R2=0.87). Again, the estimate optimum spikes/m2 was noticed 423 when the estimated grain yield of wheat was 4135 kg/ha at late sown condition through the developed functional model of Y=-2837+32.98X-0.039X2 (R2=0.83). The grain yield would be increased about 13% as compared to recommended seed rate (120 kg/ha) of wheat. Spikes / m2 had significant positive correlation with seed rate (r=0.79 at p=0.05) of wheat. Relationship between observed grain yield and predicted grain yield (when relationship between spikes/m2 and grain yield) showed a good consistency (Y=1.0006X, R2=0.94 and r = 0.97 at p<0.01). From the results of the study it is concluded that 162 kg/ha of seed rate and 423 spikes / m2 would be optimum for maximum yield) 4135 kg/ha) of wheat at late sown condition. Bangladesh Agron.

Twenty-two genotypes of maize parental line were grown during 2017-2018 at the Research field of Plant Breeding Division, Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Rahmatpur, Barisal, Bangladesh. The experiment was laid out in randomized complete block design with three replications. Heritabilty, coefficients of variability and genetic advance values were computed for days to tasseling, days to silking, days to maturity, plant height (cm), ear height (cm), cob length (cm) and diameter (cm), number of seed rows per cob, number of seeds per row, number of seeds per cob, thousand grain weight (g) and yield (g/plant). Among all the traits higher phenotypic coefficient of variation (44.53) and genotypic coefficient of variation (44.18) were observed for yield/plant. The uppermost heritability was observed in case of yield per plant (98.41) followed by 1000 seed weight (96.91). Genetic advance was highest for seeds/cob (197.87) followed by 1000-kernel weight (176.86).Greater magnitude of heritability coupled with higher genetic advance in characters under study provided the evidence that these plant parameters were under the control of additive genetic effects. Indicating that selection should lead to a fast genetic improvement of the material. Environ. Sci. & Natural Resources, 12(1&2): 33-36, 2019

An experiment was conducted at the Agronomy research field of Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur and at Regional Agricultural Research Station, Burirhat, Rangpur during Rabi season of 2013-14 and 2014-15 to find out optimum sowing date of sweet corn in potato + sweet corn intercropping system for getting maximum yield and economic return. Six treatments viz., simultaneous sowing of potato and sweet corn, sweet corn sown at 10 days after potato planting (DAPP), sweet corn sown 20 DAPP, sweet corn sown 30 DAPP, sole potato and sole sweet corn were tested in this study. Sweet corn sown at 20 DPP produced the highest potato equivalent yield (Joydebpur: 41.41 t ha-1 in 2013-14 and 42.22 t ha-1 in 2014-15 and Rangpur: 42.29 t ha-1 in 2013-14 and 42.52 t ha-1 in 2014-15). The highest gross return at Joydebpur Tk. 431050 ha-1 and at Rangpur Tk. 436248 ha-1, gross margin at Joydebpur Tk. 286805 ha-1 and at Rangpur Tk. 271985 ha-1 and benefit cost ratio at Joydebpur 2.99 and at Rangpur 3.01 were observed over the years in the same treatment. In this treatment, tuber yield was reduced 3.4-4.1% in Joydebpur and 7.8-8.4% in Rangpur due to intercropping. The result indicated that sweet corn sown 20 DAPP might be suitable intercrop combination for getting maximum yield and economic return.Bangladesh Agron. J. 2015, 18(2): 15-21
