COMPARATIVE PERFORMANCE OF DIRECT DRILLING AND CONVENTIONAL TILLAGE PRACTICES UNDER RICE-WHEAT ROTATION SYSTEM

Abstract

A field study was conducted to compare zero tillage sowing technique with the conventional sowing techniques. In zero tillage method wheat was sown directly in rice harvested plots, whereas in conventional tillage method, plots were prepared by 3 times and 6 times ploughing followed by planking. The difference of grain and straw yields was slightly higher in conventional tillage but was found statistically non-significant with zero tillage. Higher moisture retention and 13% higher income were calculated in case of zero tillage.
