Abstract: A field experiment was conducted at Main Agricultural Research Station, Dharwad on medium black soil during Kharif-2015. There were 13 treatment combinations consisted of sunnhemp and cowpea brown manuring or green manuring with 100, 75 and 50% RDN. The experiment was laid out in RBD design, with three replication. Significantly higher plant height (212.8 cm), leaf area index (5.44), drymatter production in leaves (48.0 g plant-1) and stem (78.6 g plant-1) at 90 DAS, grain weight per cob (128.4 g cob-1), grain number per cob (562.4), grain yield (5,758 kg ha-1) stover yield (8.78 t ha-1) and net returns (₹ 49763 ha-1) were recorded with maize + sunnhemp (1:2) green manuring with 100% RDN as compared to the other except maize + sunnhemp (1:2) green manuring with 75% RDN where they remained at par.
