Growth and Yield of Medicinal Rice Njavara as Influenced by Nutrient Sources Under Different Management Systems

Abstract

Experimants were conducted in 2007 and 2008 to find out the effect of nutrient sources under different management systems at Cropping Systems Research Centre, Karamana, Thiruvananthapuram, Kerala. The experiment was laid out in split plot design with four replications. The treatments consisted of four management systems viz., SRI (M 1 ), ICM (M 2 ), PoP (M 3 ) of KAU and Farmers’ practice (M 4 ) in main plot. Nutrient sources viz., organic sources (S 1 ), integrated nutrient sources (S 2 ) and inorganic sources (S 3 ) were the sub plot treatments. Farmers’ practice (M 4 ) recorded higher values of growth (height of plants, number of leaves hill -1 , leaf area index (LAI) and number of tillers per unit area) and yield attributes (No of productive tillers m -2 , grain and straw yield). Sources of nutrients did not influence growth characters in Njavara. Among the nutrient sources, higher number of grains panicle -1 , filled grains panicle -1 and crop yield (grain and straw) were recorded under integrated nutrient source than organic and inorganic sources.
