Castor based nutri-cereals intercropping system on Weed density, Weed dry weight and Weed Smothering Efficiency

Abstract

Field experiment was conducted during summer season, 2022 at Tamil Nadu Agriculture University, Coimbatore to study the influence of castor based nutri cereal intercropping on weed density, weed dry weight and Weed Smothering Efficiency. The experimental was laid out in Randomize Block Design (RBD) comprises of thirteen treatments and three replications. Results revealed that lesser weed density and weed dry weight at 30, 60 and 90 DAS was recorded under solo little millet, proso millet and foxtail millet followed by intercropping with castor + foxtail millet (1:3), castor + proso milet (1:3) and castor + little millet (1:3) when compare to paired row cropping (2:4). Solo castor recorded higher weed density and total weed dry matter production at 30 DAS, 60 DAS and 90 DAS. Castor intercropped with foxtail millet (1:3), proso millet (1:3) and little millet (1:3) recorded highest Weed Smothering Efficiency when compared to paired row cropping.
