Abstract
In a field experiment in 1988-92 at Ludhiana, Indian Punjab, rice cv. PR 108 was followed by wheat HD 2329 on the same plots. The crops were grown on 4 strips of differing soil fertility through applying no fertilizer or organic manure, 10 t FYM/ha + 50 kg N + 52 kg P + 70 kg K or 2 or 4 times this NPK rate. Superimposed on these treatments, rice was supplied with 0, 6, 9 or 12 t FYM and the residual effects studied in wheat. Mean rice grain yield was only slightly higher in the strip receiving 10 t FYM and the highest NPK rate compared with the control (6.2 vs. 5.7 t/ha). The application of 12 t FYM gave the highest grain yield of 6.7 t. Wheat grain yields were not significantly affected by soil fertility or residual effects of FYM. The application of FYM to rice increased N and P uptake in rice and P and K uptake in wheat.
