ABSTRACT

An experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka during January to April 2012 to study the effect of intra- row spacing and time of weeding on the performance of mungbean (cv. BARI mung-4). The experiment comprised with two factors viz. Intra-row spacing and Time of weeding.  Four row spacing (S1= 15 cm, S2= 20 cm, S3= 25 cm and S4= 30 cm) and four weeding treatments (W0= No weeding, W1= Weeding at 15 days after sowing (DAS), W2 = Weeding at 15 and 30 days after sowing (DAS), and W3 = Weeding at 15, 30 and 45 days after sowing (DAS) were used. There were sixteen treatment combinations under the present study. Results showed that the highest plant height (60.26 cm) was achieved by 15 cm row spacing with three times of weeding. The highest number of leaves plant-1 (11.08) and dry weight plant-1 (15.63 g) were gained by 30 cm row spacing with three times of weeding. With the treatment combination of 25 cm row spacing with two times of weeding showed very close to the combination of 30 cm row spacing with three times of weeding. Hence, the field performance from 25 cm row spacing with two times of weeding and 30 cm row spacing with three times of weeding were significantly similar; so, from economic point of view, 25 cm row spacing followed by two times of weeding was the best treatment combination.

Key Words: BARI mung-4, row spacing, weeding and field performance.
