EFFECT OF VARIETY AND NAA ON WATER RELATIONS AND YIELD OF MUNGBEAN IN KHARIF-II SEASON

Abstract

The experiment was conducted at the Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka during the Kharif -II season from June to November, 2012 to study the effect of variety and NAA on the water relations and yield of mungbean. In experiment, the treatment consisted of two variety viz., V 1 = BARI mung 2, V = BARI mung 5, and five different doses of NAA, viz., N 0 = 0 ppm NAA, N 1 2 = 20 ppm NAA, N 2 = 40 ppm NAA, N = 60 ppm NAA, N = 80 ppm NAA. The experiment was laid out in a two factors randomized complete block design (RCBD) with three replications. Variety and NAA had significant influence on water relations, yield and yield components of mungbean. The highest RWC was obtained from BARI mung 5 with 80 ppm NAA treatment. The highest exudation rate was obtained from BARI mung 2 with 40 ppm NAA treatment. The tallest plant (94.73 cm) was obtained from BARI mung 2 with 80 ppm NAA. The Longest pod was recorded in BARI mung 5, 20 ppm NAA and BARI mung 5 20 ppm interactions. The highest number of pods per plant was recorded in BARI mung 2. The maximum number of pods per plant was obtained from 20 ppm NAA. The maximum number of pods per plant was obtained from BARI mung 2 with 20 ppm NAA 4

treatment. The maximum seed yield (1.39 t ha -1 ) was found in BARI mung 5. The maximum seed yield (1.43 t ha -1 ) was obtained from 20 ppm. The highest seed yield (1.51 t ha -1 ) was obtained from BARI mung 5 with 20 ppm NAA while the lowest (1.00 t ha -1 ) from BARI mung 5 with 0 ppm NAA.
