Abstract
Field experiments were conducted in Kangra, Himachal Pradesh, India, during the 1998/99 and 2000/01 cropping seasons, to work out an integrated nutrient management schedule for maize-gobi sarson (Brassica napus subsp. oleifera var. annua) cropping system under rainfed conditions. The total grain production was higher (110.5 q/ha) when both crops in the system were given 150% of the recommended NPK and was 28 and 26% higher over the recommended fertilizer application in maize and gobi sarson, respectively. However, an application of 150% of the recommended NPK to maize and 100% NPK + 10 t/ha farmyard manure (FYM) to gobi sarson also resulted in statistically similar grain yield (108 q/ha). Application of 10 t FYM along with 100% NPK either to one or both crops increased the system productivity by 7.7% compared to the 100% NPK application. The N, P and K uptake in the system was higher when both crops in the system were given 150% NPK, followed by 100% NPK + 10 t FYM/ha application. Higher gross returns (Rs 75 251) and benefit:cost ratio (2.68) were obtained when both crops in the system were given 150% of the recommended NPK rate. Application of the recommended NPK fertilizer rate to both crops gave lower gross returns (Rs 56 786). A benefit:cost ratio of 2.18 was most practical under limited resources.
