Abstract Kernel (2814–3467 kg ha −1 ), protein (555–759 kg ha −1 ) and oil (124–1556 kg ha −1 ) yields of peanut ( Arachis hypogaea L) varied significantly due to the residual effect of organic manures and inorganic fertilisers together. It was also observed that direct application of recommended fertilisers (25 N, 72 P 2 O 5 and 37‐5 K 2 O kg ha −1 ) gave the highest kernel (3669 kg ha −1 ), protein (786 kg ha −1 ) and oil (1606 kg ha −1 ) yields. The reduction in kernel, protein and oil yield from the recommended level of fertilisers to half the recommended level of fertilisers was about 16, 15 and 12% while it was about 25, 33 and 27% with no fertiliser. Thus, the results revealed that the nutrients applied partly through organic manures and inorganic fertilisers to Kharif rice exhibits significant residual effects on the succeeding upland crop and hence the fertilisation must be considered not only for individual crops but also for the cropping system as a whole.
