| dc.description.abstract | study was conducted in All India Coordinated Research Project for Dry Land Agriculture, UAS, GKVK, Bengaluru, to evaluate the impact of contour trenches on soil and water conservation in finger millet and groundnut crops with treatments viz., contour trenches at 10 m interval, contour trenches at 25 m interval and with no trenches(control). In contour trenches with 10 m spacing in both finger millet and groundnut plots, total reduction in runoff was 36.71 per cent and 37.59 per cent respectively over the control plot and soil loss was reduced by 56.09 per cent and 58.42 per cent respectively over control plot. The higher soil moisture was recorded in both finger millet and groundnut plots with contour trenches at 10 m spacing at 45, 60, 75, 90, 105 DAS and at harvest at 15 cm and 30 cm depth. This would have resulted in better plant growth and crop yield compared to other treatments. Higher net returns (Rs.39,074 ha-1) and B:C ratio (2.51) were obtained in finger millet with contour trenches at 10 m interval. Similarly groundnut crop with contour trenches at 10 m interval recorded the higher net return (Rs. 19,180 ha-1) and B:C ratio (1.54). From the this investigation, it is concluded that in both finger millet and ground nut crops, contour trenches at 10 m spacing was found to be efficient in reducing both runoff and soil loss and also in getting higher crop yield and economic returns. | en_US |
