GROUNDNUT + SWEET CORN INTERCROPPING

The major sources of growth operating within agriculture sector may be improvement in productivity, resource use efficiency or saving in cost of production, increase in cropping intensity by intensification and crop diversification towards high value crops etc. An experiment was conducted during kharif seasons on medium black calcareous clayey soil at Junagadh (Gujarat, India) 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). The experiment results revealed that crop intensification and diversification through intercropping of groundnut with sweet corn in paired row (45-75-45 cm) (2:1) in additive series or intercropping of groundnut with sweet corn (3:1) in additive series could be adopted for obtaining higher groundnut equivalent yield and monetary returns as compared to sole groundnut on medium black calcareous clayey soil.
