Abstract:
ic experiment was cathed out in experimental field of the Department of Agronomy,
Sher-e-Bangla Agricultuml University. Dhaka to investigate the effect of nitrogen and
naphthalene acetic acid (NAA) on growth, yield contributing characters and yield of
summer mungbean (cv. BAR! mung-3) during summer season of 2005. Four levels of
nitrogen viz, 0, 20, 40 and 60kg N ha"and three concentrations of NAA viz. 0, 25 and 50
ppm were used as experimental variables. The experiment was laid out in randomized
complete block design with three replications. Results revealed that nitrogen and NAA
interacted significantly on most of the growth; yield parameters and yield of mungbean.
Plant height, number of leaves, total dry weight of plant, number of flowers, number of
pods per plant, 1000 seed weight and seed yield increased significantly by 20 kg N ha4 in
combination with 25 ppm of NAA.
