Abstract
A field experiment was conducted during the kharif seasons of 2010, 2011 and 2012 at the research farm of All India Coordinated Research Project for Dryland Agriculture, Biswanath College of Agriculture, Assam Agricultural University, Biswanath Chariali with the objectives to find out the feasibility of intercropping green gram and black gram in sesame. The experiment was conducted with 11 treatments (T1-Sesame Sole, T2-Green gram Sole, T3-Black gram Sole, T4-Sesame + Greengram (1: 1), T5-Sesame + Greengram (2: 1), T6 Sesame + Greengram (2: 2), T7-Sesame + Greengram (3: 1), T8-Sesame + Blackgram (1: 1), T9-Sesame + Blackgram (2: 1), T10-Sesame + Blackgram (2: 2), T11-Sesame + Blackgram (3: 1).) in a Randomized Block Design with three replications. Considering the sesame as base crop, sesame, greengram and blackgram were sown simultaneously as per treatment during post kharif seasons (Mid August-Mid September). It was observed that intercropping of sesame in green gram and blackgram had significantly superior value in respect of the Sesame Equivalent Yield (SEY), Land Equivalent Ratio (LER), Rain Water Use Efficiency (RWUE) net return and B: C ratio. From the pooled data of three years, the highest SEY (13.85q/ha) was recorded by T8-Sesame + blackgram (1: 1) followed by Sesame + Greengram (2: 2) and Sesame + blackgram (2: 1). The highest LER (1.42), RWUE (7.42kg/ha/mm), Net return (39, 374/ha) and B: C ratio(4.40) was also recorded in Sesame + Blackgram (1: 1).
