Abstract
A field experiment was conducted at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat, India during summer-kharif seasons of years 2017 and 2018 to study the “Influence of legume crop residues and nitrogen management on productivity of maize (Zea mays L.) in legume-maize cropping system under middle Gujarat conditions”. The experimental field had an even topography with a gentle slope having good drainage and loamy sand in texture. The soil of the experimental field at 0-15 cm depth was low in organic carbon and available N, medium in available phosphorus and potassium and slightly alkaline in reaction. There were eighteen treatment combinations comprised of three legume crops grown in summer season; green gram (C1), groundnut (C2) and cluster bean (C3) designated as vertical strips, two residue management treatments viz., residue removal (R0) and residue incorporation (R1) as horizontal strips and three nitrogen levels in kharif maize viz., 100% RDN (N1), 75% RDN (N2) and 50% RDN (N3) designated to intersectional sub plot, tested in strip-split plot design. The whole treatment set was replicated four times.
