Abstract

An experiment was conducted to assess the performance of rice under the system of rice intensification (SRI) in comparison with the conventional system of cultivation. The field studies were carried out during the rabi seasons of 2007 and 2008 in the lateritic sandy clay loam soils of RARS, Pattambi, Palakkad district in Kerala, having pH 5.00 and medium fertility, in RBD with 16 treatments replicated thrice. The weed density and dry weight were higher in SRI. Growth parameters such as plant height, number of tillers hill-1 and dry matter production hill-1, and yield parameters like number of productive tillers hill-1 and length of panicle were significantly higher in the SRI treatments, whereas the tiller density, dry matter production per unit area, the grain yield per hectare and the B:C ratio were higher in the conventional system. Hence it is concluded that in the irrigated rice tracts of Kerala conventional system of rice cultivation is more advantageous than the SRI in terms of crop yield and economics of cultivation.
