Abstract: A field experiment was conducted to evaluate the effect of tillage and cropping system on soluble and exchangeable phosphorus fraction in soil under irrigated agro-ecosystem of the eastern indo-Gangetic plains. The experiment was designed in factorial randomized block design with 9 treatments, each replicated thrice at two depths i.e., 0-15&15-30 cm. Three treatments in main plot for Tillage practices were: Zero tillage (ZT), Permanent Bed (PB) and Conventional tillage (CT) and three treatments in sub plot for cropping system were Rice-Wheat (R-W), Maize-Wheat(M-W) and Maize-Maize (M-M). The results shows that soluble and exchangeable phosphorus was found significantly higher in zero tillage system (ZT) followed by Permanent bed (PB) and conventional tillage (CT) system at both the level of depth. However, cropping systems did not show significant variation in soluble and exchangeable phosphorus content. Although, at both the depth levels Rice-Wheat (R-W) system had highest soluble and exchangeable phosphorus content followed by Maize- Wheat system and Maize-Maize system. In case of total phosphorus, same trend is observed at both levels of depth. However, the trend was reversed in case of tillage practices at 15-30 cm depth where conventional tillage (CT) showed higher total phosphorus content (151.71 mg P kg-1) than other tillage practice.
