Effect of Phosphorus and Boron Application on the Nutrient Contents of Grain and Stover of Mungbean

Abstract

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the period from February 2012 to May 2012 to investigate the effect of four different doses of phosphorus (0, 20, 40 and 60 kg ha-1 ) and boron (0, 1.0, 1.5 and 2.0 kg ha-1) on nutrient content of summer mungbean cv. BINAmung-8. The experiment was laid out in a randomized complete block design (RCBD) with sixteen treatment combinations having three replications. The contents of N, P, K, Ca, Mg and S influenced significantly due to different treatments. The uptakes of N, P, K, S, Ca and Mg in grain and stover were expressively affected due to different treatments. In grain, combination of 60 kg P ha-1 × 2.0 kg B ha-1gave the maximum contents of N, P, K, Ca, Mg and S. The highest content of P, K, Ca, Mg and S in stover was obtained in the combination of 60 kg P ha-1 × 2.0 kg B ha-1 and N content in stover was not significant. The results suggest that mungbean crop may preferably be fertilized with a combination of 60 kg P ha-1 × 2.0 kg B ha-1to obtain better quality of BINAmung-8 in the agroclimatic condition of the study area.
