Evaluation of suitable rice genotype suitable under sri and traditional methods of cultivation

Abstract

The investigation was conducted during Kharif season of 2006 with 32 genotypes of rice at Research Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). On the basis of overall performance, the genotypes Poornima, Danteshwari, R-1033-968-2-1 and R-1248-1489-2-822-1 performed better for the entire attributes viz. yield, number of tillers, and biomass under SRI method of rice cultivation. The hybrid variety IRH-5 performed better under traditional method with continuous water level. Out of 32 genotypes, 21 genotypes showed higher grain yield under SRI method of cultivation. This might be due to the fact that yield is a function of growth characters and yield attributes. The grain is the result of growth and yield attributing character of crops. If yield, tiller as well as biomass are considered as better attributes for examining the performance of any genotype namely Poornima, Danteshwari, R-1033-968-2-1, R-1248-1489-2-822-1, R-1099-25-96-1-1, R-1030-22-97-1-1, R-1250-1557-895-1, SHAMLESHWARI, RDG-1, IR-36, Madhuri, R-1182-167-2-1, and R-1162-1667-1-1 seems better under SRI method of cultivation.
