Abstract: The present study aimed to determine the effect of tillage and brown manuring in sandy loam soil under maize (Zea mays L.)-wheat (Triticum aestivum L.) sequence. Six treatments implemented were Conventional tillage (CT); Deep tillage once in three years (DT); Conventional tillage with integrated nutrient management (CT-INM); Conventional tillage with brown manuring in maize + cowpea (1:2) and wheat + pea (4:1) ratio (CT-BM); Conservation tillage (CST) ; Conservation tillage with brown manuring (CST-BM). Maize equivalent yield (MEY) was 51.8% higher in CT-INM, over control; DT, CST, CST-BM and CT-BM produced 4.92, 14.1, 30.8 and 39.3 % higher yield over control (CT), respectively. The mean soil organic carbon (SOC) was 12.1, 11.3 and 17.7% higher under CT-BM, CST, CST-BM treatments, respectively, over the control (CT) in surface soil. Brown manuring in conjunction with both conventional (CT-BM) and conservation tillage (CST-BM) reduced soil loss to the extent of 91.70% and 93.32% as compared to CT. The highest net return per rupee of investment was recorded in CT-INM, being lowest in DT.
