Abstract
Effect of irrigated and rainfed cropping systems on carbon and nitrogen mineralization was studied. Maximum C and N mineralization observed under irrigated cropping systems than rainfed. Sorghum-chickpea- groundnut showed highest mineralization under irrigated condition. While monocropping and intercropping with legumes enhances the rate of mineralization under rainfed situation. Mineralization was found to be highest during grand growth period of crops. Application of integrated nutrient supply increased C and N mineralization as compared to their individual application. The FYM+wheat straw+green manuring application augmented the mineralization under soybean- wheat crop sequence.
