GROWTH AND YIELD RESPONSE OF MUNGBEAN VARIETIES TO PLANTING GEOMETRY

Abstract

A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during the period from March to June 2021, to study the growth and yield values of mungbean varieties to planting geometry. The experiment comprised of two factors like, (i) varieties (3) viz., V 1 = BARI Mung-5, V 2 ii = BARI Mung-6, V 3 = Binamoog-8 and (ii) planting geometry (4) viz., P 1 = Broadcast, P 2 =Paired row (15 cm × 10 cm) cm, P 3 = Square planting (20 cm × 20 cm) and P 4 = Row sowing (30 cm × 10 cm) and followed split plot design with three replications. Result showed that, variety, planting geometry and their combination had significant effect on growth, yield contributing parameters and yield of mungbean. Binamoog-8 showed maximum yield (1.76 t ha ) with pods plant -1 (21.37), pod length plant -1

(7.09 cm), seeds pod -1 (11.98), 1000-seed weight (50.76 g), biological yield (4.34 t ha -1 ) and harvest index (40.65 %) maximum compared to others varieties. In case of planting geometry results revealed that, the conventional spacing management (30 cm × 10 cm) influenced plant to yielding maximum (1.59 t ha (21.67), pod length plant -1 ) with several yield contributing characters like pods plant -1

(7.33 cm), seeds pod -1 (12.45) and 1000-seed weight (49.25 g). In case of different planting geometry the lowest seed yield (1.47 t ha ) was obtained from P 1 (Broadcasting). Binamoog-8 along with spacing 30 cm × 10 cm (V 3 P 4 ) found suitable combination for maximum growth, yield and yield contributing parameters of mungbean. Thus, this management could help farmers to have increased production of mungbean.
