Abstract

The field experiment was conducted to investigate the effect of primary nutrients (NPK) on growth, yield and yield attributes of mungbean. The experiment was laid out in a randomized complete block design with three replications and consisted of four level of primary nutrients (N:P:K) viz. F *0 = no NPK added, F1 = 8:10:12 kg ha^-1, F2 = 16:20:24 kg ha^-1 and F3 = 24:30:36 kg ha[1]1 of N:P:K. Increasing the levels of primary nutrients significantly influence the growth, yield and yield attributes of mungbean except stover yield and harvest index. The highest plant height, number of pod plant^-1, weight of seed plant^-1 and seed yield were obtained from 16:20:24 kg N:P:K ha-1 whereas 24:30:36 kg N:P:K ha-1 produced the highest number of leaf plant^-1, number of branch plant^-1, seed pod^-1, weight of seed pod^-1 and 1000-seed weight. Increased rate of nutrients increased the pod plant^-1, seed weight pod^-1 and seed yield up to N:P:K @ 16:20:24 kg ha^-1 and then declined. From the results of this study it could be suggested that application of primary nutrients (N:P:K) @ 16:20:24 kg ha^-1 optimum for BARI mung-6 at Batiaghata upazila in Khulna district of southwestern Bangladesh
