High price, continuous degradation of soil fertility and low organic matter are considerable reasons of low soil fertility and less productivity of maize in Paki stan. Nitrogen use efficiency and nutrient availability can be enhanced by adding organic matter in soil through organic (green manuring) amendments. A field research experiment was conducted to evaluate the effect of green man uring on the yield of autumn maize (Zea mays L.) by reducing recommended dose s (250, 125, 125 kg ha-1) of NPK up to 50%. Experiment was conducted at Agronomic Research Area, Department of Agronomy, University of Agriculture, Faisalabad during the autumn season 2014. Triplicated r andomized complete block design was followed to conduct experiment. Plot size was 6 m × 4.5 m with row to row distance of 75 cm. Comparative efficiency of seven different crops (Cowpea, Mungbean, Green gram, Mashbean , Clusterbean, Soyabean, Jantar ) as a source of green manure was evaluated by reducing recommended dose of fertilizers (RDF) upto 50% . Standard procedures for recording parameters related to yield and quality of maize were followed. Incorporation of green manures with reduced quantity of inorganic fe rtilizers significantly increased the maize yield. Maximum plant height at maturity (227 cm), cob length (21.66 cm), number of grain rows per cob (16.26), number of grains per cob (438), 1000-grain weight (300.3 g), grain yield (7.56 t ha -1), biological yield (19.63
