Abstract
Field experiments were conducted for two years to work out the balance. sheet of availablesoil nitrogen as affected by some maize based cropping systems under rainfed conditions.Leguminous crop rotation resulted In significant build-up of available nitrogen contentof soil as compared to cereal-cereal or cereal-oilseed rotations. Highest net gain of soilavailable nitrogen resulted from maize + soyabean-wheat crop rotation during both the years.Malze-toria-wheat proved to be an exhaustive cropping sequence in respect of available nitrogencontent of soil.
