ABSTRACT
The field experiment was conducted on wheat at the Central Research Farm (CRF), Gayeshpur encompassing the new alluvial zone of West Bengal, India. The experiment was laid out in factorial RBD with three treatments [T1: 100:50:50 :: N:P:K kg/ha, T2: 120:60:60 :: N:P:K kg/ha, T3: 150:75:75 :: N:P:K kg/ha], eight sampling dates and three depth of sampling with three replications. The recoveries of plant nutrients (mg/kg) were 11.78 - 32.69 for N, 1.63 - 3.27 for P and 11.11 - 25.48 for K. The variations in soil moisture significantly governed variations in accumulations of N, P and K in wheat, to the tune of 46.8% in N, 79.9% in P and 78.6% variations in K accumulation. NPK uptake by wheat at harvest is significantly increased with increasing application of N, P and K fertilizers.
Key words: Nutrient recovery, Accumulation, Soil moisture
