Productivity of soils amended with different organic manures and tillage practices in rice-wheat system.

A field experiment was conducted with rice-wheat cropping system at IARI, New Delhi for two Kharif (rainy) and Rabi (winter) seasons during 2006-08. The main plots comprised two tillage treatments viz. puddled and non-puddled in rice and conventional tillage and no-tillage in wheat. The sub-plots included seven fertilizer treatments including recommended doses of urea (120 kg N -1 ha ), urea + FYM, urea + green manure (GM), urea + municipal solid waste (MSW) compost. Results showed that the growth and yield of rice and wheat were higher under puddled/ conventional tillage condition compared to non-puddled/ no-tillage conditions. Application of organic matter with recommended dose of mineral fertilizer gave the higher plant growth, yield attributes, grain and straw yield compared to other treatments.
