Uptake Of Different Nutrient Elements By Legume Crops In Wheat -Legume- T. Aman Cropping Pattern

Abstract

A study on nutrient uptake by different legume crops was carried out at two locations–one at Bangladesh Agricultural University farm Mymensingh and another at Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jamalpur. The objective was to find out the optimum concentrations of different nutrient elements and its uptake by legume crops in a Wheat-Legume-T. Aman cropping pattern. The uptake of different elements was markedly varied by legume crops at both the locations in two consecutive years of the study. It was also noticed that cowpea removed the highest quantity of nutrient elements from the soils in the treated plots compared to mungbean and blackgram. Besides, stover received the maximum contents of potassium followed by nitrogen, phosphorus, and sulphur which was significantly different over legume seeds.

Keywords: Nutrient uptake; legume crops.
