Abstract

Crop residue removal in conventional tillage (CT) can cause the depletion of soil nutrients (such as N, P, K) and organic carbon resulting in negative nutrient balance/depleted soil fertility. No-tillage (NT) is seen as a good substitute for CT in terms of preserving soil fertility and enhancing the soil productivity. The present study carried out in black soil of central India comprising of 2 tillage systems and 3 crop rotations to compared the effects of long-term conventional and no-tillage practices on available soil nutrients, soil organic carbon and crop yield differences in different cropping systems. Conventional tillage and No-till were factored into, soybean-wheat, maize-wheat and maize-gram systems. The long-term no-tillage treatment resulted in higher soil organic carbon (0.95%), available soil nitrogen (222.61 Kg ha-1), phosphorus (24.62 Kg ha-1) and potassium (583.63 Kg ha-1) contents at the 0–10 cm depth than the conventional tillage treatment. Crop productivity in terms of soybean grain equivalent yield (SGEY) was significantly higher in NT (41.42 quintal ha-1) compare to CT (35.36 quintal ha-1). The study proven that no-tillage is an effective strategy to improve soil fertility (organic carbon and available nutrients) and crop yield of different cropping systems in black soils of central India.
