INFLUENCE OF PLANTING GEOMETRY ON GROWTH AND YIELD OF BLACKGRAM VARIETIES

Abstract

An experiment was carried out at Agronomy farm, Sher-e-Bangla Agricultural University, Dhaka to investigate the influence of system of crop intensification method use in blackgram cultivationduring the period from March to June, 2015. The trial comprised of three varieties of blackgram viz. V 1 = Munshigonj Local, V 2 = BARI Mash-2 and V = BARI Mash-3 and five plant spacings viz. SP 1 = 30cm × 10cm (control), SP =20cm × 20cm SP 3 =30cm × 30cm, SP 4 = 40cm × 40cm and SP = 50cm × 50cm. The experiment was laid out in a split-plot design with three replications having variety in the main plots and plant spacing in the sub-plots. The fertilizers were applied as basal dose @ N, P and K as 20, 17.20 and 17.6 kg ha -1 5 , respectively at final land preparation in all plots. Results of the experiment revealed that, BARI Mash-2 influenced significantly most of the growth, yield attributes and yield of blackgram. BARI Mash-2 produced maximum seed yield (1.38 t ha ) and plant spacing 50cm × 50cm gave the higher seed yield pant -1 (17.31 g) but 30cm ×10cm gave highest seed yield (1.49 t ha -1 ). While the highest seed yield (1.80 t ha -1 ) was recorded form BARI Mash-2 with plant spacing 30cm ×10cm and the minimum (0.66 t ha -1 ) was recorded from Munshigonj local along with spacing 50cm × 50cm
