An experiment was conducted during kharif seasons of year 2018-19 and 2019-20 on medium black calcareous clayey soil at Junagadh (Gujarat) to study crop intensification and diversification through groundnut (Arachis hypogaea L.) + sweet corn (Zea mays var. saccharata) intercropping system. The groundnut (cv. GG-20) was mix/intercropped with sweet corn (cv. Sugar-75) and pigeonpea (cv. GJP-1). Ten treatments comprising mix/intercropping systems viz., sole groundnut, sole sweet corn, sole pigeonpea, groundnut + sweet corn in 1:1, 2:1 and 3:1 row ratio in replacement series, groundnut + sweet corn (3:1 in additive series), groundnut + sweet corn with paired row (45-75-45 cm) (2:1 in additive series), mix cropping of groundnut 80% + sweet corn 20% and groundnut + pigeonpea (3:1 in replacement series) were evaluated in randomized block design with three replications. The productivity of these systems in terms of groundnut pod equivalent yield was significantly higher (2338 kg/ha) with intercropping of groundnut + sweet corn with paired row (45-75-45 cm) (2:1 in additive series) followed by intercropping of groundnut + sweet corn (3:1 in additive series) (2156 kg/ha) than sole groundnut (1658 kg/ha) and other mix/intercropping systems. The biological efficiency of the mix/intercropping systems in terms of the LER (1.537), LEC (0.545) and ATER (1.414) were also recorded significantly higher under intercropping of groundnut + sweet corn with paired row (45-75-45 cm) (2:1 in additive series).
