In a field investigation on Fe toxic Haplaquent, (1987, 1988), grain yield increased spectacularly, by the application of P @ 20 kg P ha−1. The highest yield was observed in diammonium phosphate treated plots followed by Purulia rock phosphate and superphosphate in conjunction with Mussoorie rock phosphate (1: 1). The P: Fe and K: P ratios proved a better tool in predicting the yield under Fe toxic soil conditions.
