SUBSTITUTION OF FERTILIZER NITROGEN THROUGH ORGANIC SOURCES IN MAIZE -WHEAT CROPPING SYSTEM IN INDO-GANGETIC PLAINS
• Application of SGM either alone or in combination with WS with moderate levels of fertilizer N substitute for substantial amount of fertilizer N and consequently enhanced crop productivity with higher profitability maintaining soil fertility in maize-wheat cropping system. • Application of leguminous green manure and previous crop residues (wheat residues) in soil can potentially deal the issues of stagnation in productivity, declining factor productivity and soil fertility depletion.
