EFFECT OF SEED SIZE AND SPACING ON GROWTH AND YIELD OF MUNGBEAN

Abstract

An experiment was conducted at the Agronomy field, Sher-e-Bangla Agricultural University, Dhaka, during March to May, 2014 to study the effect of seed size and spacing on the growth and yield of mungbean. The experiment was consisted of three seed sizes; viz., small (3.2mm), medium (3.2 mm to 4mm) and large ( >4mm) and four row spacings (20cm, 25cm, 30cm and 35cm). The experiment was laid out in Randomized Complete Block Design (RCBD) (factorial) with three replications. The results showed that growth, yield and yield attributes of mungbean significantly influenced by seed sizes, spacings and their combinations. At harvest, medium seed sized gave the longest plant height (44.8 cm), maximum number of leaves plant

(10.0), the highest leaf dry weight plant -1 (7.6g), flower and pod dry weight plant -1 (3.4g), total plant dry weight (15.5g), biological yield plant (3.0g), harvest index (0.38) and seed yield (1.58t ha gave the highest seed yield (1.57t ha -1 -1 -1 ). The plant of 30cm spacing ), biological yield (3.8 t ha index (0.39). The combined effect of medium seed size (3.2-4mm) and sowing at 30 cm spacing showed maximum grain yield (2.4 t ha ) with higher value of harvest index (40.00%). -1 -1 ), harvest -1
