Abstract

In order to enhance the legumes potential advantages on the cereal yield in intercropping system by nitrogen direct transfer from legume to cereal, an intercropping experiment was conducted during Kharif season 2022 at Lovely Professional University, Phagwara Punjab. The experimental design was randomized block design with three replications, nine treatments were applied. Evaluation of the soles plantings and intercropping’s was performed on basis of several intercropping indices (Maize equivalent yield (MEY), Land equivalent ration (LER), land equivalent coefficient (LEC), area time equivalent ratio (ATER), aggressivity (A), and competitive ration (CR)) the monetary advantage (MA) and net returns. After data analysis, competitivity indices indicated that higher yields advantages of maize in intercropping in maize + black gram (1:2) (MEY = 11671.03 kgha-1), LER is 2.23 and LEC (0.43) in maize + black gram (1:2) intercrops respectively. ATER showed highest value (1.70) in maize + black gram (1:2). Aggressivity showed dominance of legumes in all intercrops, against the CR showed that the competitivity was stronger (2.48) in black gram than French bean. MA of ₹ 14082.1 in maize + black gram (1:2) had determined that intercropping as an economic efficiency intercrop than other mixtures. Maize – black gram intercropping resulted in an additional net return gain of ₹ 189796.02 compared to just maize. These results suggest there is considerable potential for small farmers to increase their yields and profits by intercropping.
