The present investigation was undertaken in a long-term experiment on IPNS in rice-wheat cropping system at the Badiarkhar farm of CSK HPKV Palampur Himachal Pradesh. Twelve treatments viz., control (no fertilizer/manure), 50, 75 and 100% NPK each to rice and wheat through fertilizers, 50% NPK to rice and 100% NPK to wheat through fertilizers, 50% substitution of N through FYM, wheat straw and green manure in rice and 100% NPK through fertilizers in wheat; 25% substitution of N through FYM, wheat straw and green manure in rice and 75% NPK through fertilizers in wheat; and farmers’ practice (40% NPK through fertilizers to each crop plus 5 t FYM/ha on dry weight basis to rice) were evaluated for a period of two years (2014-15 and 2015-16) with four replications. Increasing level of NPK application to wheat increased the number of shoots per metre square, maximum being in the treatment T6 (50% NPK with 50% N through FYM to rice and 100% NPK was applied through fertilizers to wheat) and lowest in T1 (control) during both years. Significantly more plant height of wheat was recorded when application of 100% NPK to each crop was made (T5) during 2014-15 and 50% NPK with 50% N through FYM to rice and 100% NPK to wheat (T6) during 2015-16. Shortest crop stature was recorded under T1 (control) during both the years. The minimum days to flowering and maturity in wheat were in T6 during both the years. T6 gave significantly higher grain and straw yield of wheat during 2015-16. On an average T6 where 50% NPK in combination with 50% N (FYM) was applied to rice and 100% NPK to wheat was found to be the best treatment for getting higher productivity and profitability. Treatments have significant effect on grain yield of wheat during 2015-16 and straw yield during both the years.
