EFFECT OF ROW SPACING AND METHODS OF WEEDING ON TILE YIELD OF MUNGBEAN (Vigna radiata L.)

Abstract

An experiment was conducted at the Sher-e-Bangla Agricultural University Farm. Dhaka, during K/tar/f-I season from the month of March to June, 2007 to study the effect of row spacing and methods of weeding on the yield of mungbean (cv. BARI murig-5). The treatments consisted of four row spacing viz. 20 cm, 25 cm, 30 cm, 35 cm and three weeding methods viz. hand weeding, raking and wheat straw mulching. The experiment was laid out in randomized complete block design (RCBD) with three replications. Row spacing and methods of weeding had significant influence on growth, yield and yield components of mungbean. Results showed that the tallest plant height was obtained from spacing 20 cm and mulching with wheat straw treatments. But, the highest number of leaves was obtained from the interaction treatment of 35 cm spacing and hand weeding. The highest dry weight of weeds per was recorded in 35 cm spacing and raking. The highest number of pods per plant (12.45), number of seeds per pod (13.07), thousand seed weight (41.10 g), yield per hectare (1.47 t) and harvest index (27.74 %) was recorded in 30 cm spacing and hand weeding interaction treatment
