Effect of Spatial Arrangements on Yield and Competition of Jute (Corchorus Olitorius l.) and Mungbean (Vigna radiata l. Wilczek) in Intercropping

Low profitability from jute farming, declining area and negligible pulse are the rising concerns of farmers Indo-Bangla subcontinent. This paper evaluated extent yield competition in jutemungbean intercropping with varying spatial geometry under alternate single row (SR) double (DR) planting. Two 2-year field experiments were conducted independently for two systems plantings involving (cv NJ 7010) mungbean TMB-37) arranged systematic designs 3×3×3 spacing plant density combinations three replications. Yield was assessed using indices. Intercropping found productive profitable compared to sole cropping. Land equivalent ratios (LER) × time (ATER) always exceeded unity.
