dc.description.abstractThe field experiment was conducted to study the effect of integrated nutrient supply system in rice-wheat cropping system during 2016-17 at Badhiarkhar Research Farm of Department of Agronomy, Forages and Grassland Management, CSKHPKV, Palampur. The treatments comprising of T1 - Control (No fertilizer, no manure), T2 - 50% NPK to both rice and wheat, T3 - 50% NPK to rice and 100% NPK to wheat, T4 - 75% NPK to both rice and wheat, T5 - 100% NPK to both rice and wheat, T6 - 50% NPK + 50% N (FYM) to rice and 100% NPK to wheat, T7 - 75% NPK + 25% N (FYM) to rice and 75% NPK to wheat, T8 - 50% NPK + 50% N (wheat cut straw) to rice and 100% NPK to wheat, T9 - 75% NPK + 25% N (wheat cut straw) to rice and 75% NPK to wheat, T10 - 50% NPK + 50% N (green manure) to rice and 100% NPK to wheat, T11 - 75% NPK + 25% N (green manure) to rice and 75% NPK to wheat and T12 -Farmers‟ Practice (40% NPK and FYM 5 t/ha to both the crops) were evaluated in a randomized block design with four replications. Soil of the experimental site was silty clay loam in texture, acidic in reaction, high in available nitrogen, and medium in available phosphorus and potassium. Significantly higher absolute growth rate and plant height, higher dry matter accumulation, number of shoots, CGR & RGR were recorded in T6 incase of rice. In case of wheat, initial plant stand at complete emergence, plant height, number of shoots and dry matter accumulation at different stages were also maximum in T6. The days taken to 50% flowering/earing as well as maturity were minimum in the treatment comprising of 50% NPK along with FYM in rice (T6).The study revealed that T6 resulted in higher tillers, panicles, grains per panicle, 1000 grain weight, seed, straw & biological yield of rice. In case of wheat, higher number of spikes, number of grains per spike, length of spike, grain weight per spike, 1000 grain weight, seed, straw and biological yield were found in T6. Pooled data of 22 years from 1994-95 to 2016-17 showed that the maximum yield was recorded in T6. The net returns of the system was maximum in treatment T6 while the benefit cost ratio was maximum in treatment T5. The treatment comprising of 50% NPK + 50% N (FYM) to rice and 100% NPK to wheat (T6)was found to be the best treatment for getting higher productivity and profitability followed by T10 and T5.en_US
