Present investigation was carried out at the Research Farm of All India Coordinated Research Project for Dryland Agriculture (AICRPDA), College of Agriculture, Indore during kharif 2017. The experiment was laid out in a randomized block design (RBD) replicated thrice with eight different treatments involving combinations of green manuring and intercropping of sunhemp, soybean and maize crops. Soybean (JS 95-60) and Maize (K 604 hybrid) were grown as rainfed crops in Kharif 2017 with 20:60:40 and 120:60:40 kg ha-1 recommended dose of N:P2O5: K2O fertilizers, respectively with Sunhemp as a green manure crop. The response of soybean and maize crops in terms of growth and yield attributes and yield was studied. The results revealed that the growth and growth attributes of soybean and maize were found higher under the incorporation of green manuring and soybean + maize intercrop. The green manuring and intercropping enhanced plant height, branching, nodulation, pods per plant and seeds per pod in soybean by 7-11%, 11-34%, 9-18%, 33% and 7-12% higher, respectively over the sole soybean. Similarly, the grains per cob in maize was found 20-23% higher under green manuring while it was 20% higher under maize+soybean intercropping. The seed yield of soybean was found decreased by 7-17% and 45% under green manuring and maize intercropping, respectively. However, the maize grain yield showed 3-5% increment under green manuring while it was reduced by 48% in intercropping. The data on Economic analysis showed highest net returns of Rs. 21581 Rs ha-1 and benefit: cost ratio of 2.25 under green manuring/intercropping.

Key words:Sunhemp, Green manure, Intercrop, Soybean, Maize, Yield.
