EFFECT OF NITROGEN AND SULFUR ON THE GROWTH AND YIELD OF MUNGBEAN

From March to May 2019, a field experiment was performed at the Sher-e-Bangla Agricultural University's research farm in Dhaka to study the influence of nitrogen and sulfur on mungbean development and yield in a Randomized Complete Block Design (RCBD) with three replications. Three amounts of nitrogen (0, 15 & 25 kg ha-1, denoted as N0, N1, N2 correspondingly) and three levels of sulfur were used in the experiments ( 0, 20 & 25 kg ha-1 designated as S0, S1 & S2 respectively). With increasing nitrogen dosages up to 15 kg N ha-1, the number of seeds per pod, weight of 1000 seeds, and yield (1.11 t ha-1) rose considerably (N1). However, increasing nitrogen dosages up to 25 kg N ha-1 resulted in substantial increases in plant height at final harvest, number of branches, number of pods, and stover production (2.76 t ha-1) (N2 treatment). However, up to the treatment S1, plant height at final harvest, number of branches, weight of 1000 seeds, yield (1.04 t ha-1)and stover yield (1.86 t ha-1) all increased considerably (20 kg S ha-1). Plant height at final harvest, number of branches, seeds per pod, pod length, weight of 1000 seeds, yield (1.57 t ha-1), stover yield(2.53 t ha-1 ) increased up to N2S2 (25 kg N ha-1 + 25 kg S ha-1 ), but N2S1 treatment combination (25 kg N ha-1 + 20 kg S ha-1) showed statistically similar results as compared to N2S2 (25 kg N + 25 kg S ha-1) treatment.
