A response to phosphorus (P) was observed in rice in the later years of the experiment, whereas in wheat a response to P was observed from the initial years. Applications of farm yard manure (FYM) in combination with nitrogen (N) and P resulted in better wheat yields than applications of mineral fertilizer only. A residual effect of FYM was also observed in the rice crop. Incorporation of a green manure, sesbania, increased the rice yield but had no residual effect on wheat. The application of potassium (K) significantly increased the wheat grain yield and grain weight. Olsen P was below the critical level of 5 u/g soil were P was not applied. Exchangeable K was also below the critical level of 78 u/g soil in all treatments, including the FYM treatment.Collection: CIMMYT Publications Collection
