  • Product Description

The performances of two blackgram (Vigna mungo L) varieties were evaluated under various levels of nitrogen fertilization. The accumulation of dry matter in different organs maximized at 80 kg N ha-1. In contrast, light transmission ratio (LTR) was decreased while light interception (LI) increased with the increasing nitrogen levels. A best-fit positive linear relationship was detected between leaf chlorophyll and leaf nitrogen content with different nitrogen levels. Unexpectedly accumulation of N, P and K in two varieties was not differed significantly. The uptake of N, P and K increased up to 60 kg N ha-1 then decreased with increasing nitrogen levels. Among the varieties BARI mash 3 showed better performances than BINA mash 1 regarding most of the characters. The longest plant was measured with 100 kg N ha-1 whereas largest leaf area was detected at 80 kg N ha-1. Application of 60 kg N ha-1 favored most of the yield contributing characters that contributed maximum grain yield production. Of the two varieties, BARI mash 3 out yielded BINA mash 1 at all nitrogen levels. It was obvious that grain yield of blackgram can be increased substantially with judicious application of N.
