Evaluation of Management Practices for Rice-Wheat System Under On-farm Condition for Low Hill Zone of Himachal Pradesh

摘要

On-farm experiment was conducted in sub-montane and low hills sub-tropical zone of Himachal Pradesh to study the impact of application of recommended dose of nutrients and full package of practices with and without farm yard manure (FYM) along with farmers' practice in rice-wheat cropping sequence under irrigated conditions for four consecutive cropping seasons during 2007-08 to 2010-11. The single intervention of applying recommended fertilizer nutrients over the existing farmer's practice increasedthe overall grain yields of rice and wheat by about 18.1 and 21.9%, respectively. The application of recommended package of practices further increased rice and wheat yields by about 8.1 and 10.2%, respectively and rice grain equivalent yield and net returns by about 30.4 & 40% over the farmer's practice. Both crops also responded to the application of FYM which significantly increased rice and wheat grain and straw yields, rice grain equivalent yield and gross and net returns overthe other treatments.
