Effects of rate and frequency of applied p on crop yields, p uptake, and fertilizer p use-efficiency and its recovery in a groundnut-mustard rotation
A field experiment was conducted for 5 years (1992/93–1996/97) on Tolewal sandy loam soil (Typic Ustochrepts) in the subtropical region of northwest India (Ludhiana), to evaluate the effect of four rates of fertilizer P (0, 20, 30 and 40 kg P2O5/ha) applied at three frequencies representing direct,...
