A field experiment was designed to determine the effect of mineralized nitrogen (N) through decomposition leafy biomass agroforestry tree species as residues underscore its uptake by maize under Sudan savannah conditions. The laid out 3 x 4 2 factorial in a split-split plot design with three replicates for two cropping seasons. factors considered include: control, (Albizia lebbeck and Parkia bi...

A field investigation was conducted at Agronomy research farm A. S. (P.G) College, Lakhaoti, Bulandshahr during rabi seasons of 2006 and 2007. The treatments consisted combination four cropping systems viz. chickpea sole (M1), linseed (M2), chickpea+ 2:1 ratio (M3) pigeonpea + 4:2 (M4) in main plots; two irrigations vegetative stages (30-40 days) flowering stage (70-75 (S1) one irrigation (S2) ...
