Abstract: A field experiment was conducted at the Student’s Instructional Farm of C. S. A. University of Agriculture and Technology, Kanpur during kharif season of 2019 to find out “Studies about in-situ green manuring and nitrogen management on yields, economics and quality of maize (Zea mays L.)” The twelve treatments were comprises i.e. control (No green manure and no nitrogen), no green manure+ 100kg N/ha, no green manure+ 150kg N/ha, no green manure+ 225kg N/ha, maize sown after in situ green manuring + 0 kg N/ha, maize sown after in situ green manuring + 100 kg N/ha, maize sown after in situ green manuring + 150 kg N/ha & maize sown after in situ green manuring + 225 kg N/ha, maize sown into standing dhaincha + 0kg N/ha, maize sown into standing dhaincha + 100kg N/ha, maize sown into standing dhaincha +150kg N/ha & maize sown into standing dhaincha + 225kg N/ha with Randomized Block Design and replicated thrice. The soil of the experimental plot was sandy loam in texture with pH 7.9 & EC of 0.32 ds/m at 25°C. It contained 0.43% organic carbon. Results revealed that the plots where maize was sown after incorporation of green manure and with the supply of 150 kg N/ha treatment promoted significantly the yield, economics and quality as compared to all remaining treatments. The treatment of maize sown after in-situ green manuring has done and at a dose of 225 kg N/ha observed grain yield (82.54 q/ha) which is non significantly higher than 150kg N/ha (81.92q/ha) with a net return of Rs.1,13,514.50/ha at 150kg/ha and the maximum nitrogen uptake & nitrogen use efficiency were recorded in maize raised after dhaincha green manuring with 225 and 100 kg nitrogen/ha, respectively over other treatments.
