Nutrient Management in System of Rice Intensification (SRI)

A field experiment was conducted during rabi (August, 2010-January, 2011) season in Wetland Farms of Tamil Nadu Agricultural University, Coimbatore, to evaluate the integrated nutrient management practices under system of rice intensification. The main objective of the study was to optimize the use of different sources of nutrients under SRI. The experiment was laid out in a randomized block design with three replications. It is evident from the present investigation that application of 75% inorganic N + 12.5% N through FYM + 12.5% N through well decomposed PM is found to be a better option for getting higher productivity and economic returns of rice under system of rice intensification.
