| Abstract: | The goal of this study was evaluation of three soil moisture levels measured with electronic sensors in alfalfa crops (T1 = 5-15 cbar, T2 = 50-75 cbar and T3 90-110 cbar), previously calibrated for the study area. Variables such as dry matter yield (DM) and irrigation water productivity (PA) were valuated. The values obtained were 6.65 6.35 at 5.27 t ha-1 for DM and 2.67 4.02 at 3.87 kg m-3 for PA as a function of crop Evapotranspiration (ETc ) With values of 248.64, 157.96 and 136.30 mm for T1, T2 and T3 respectively. These results allow us to conclude that keeping the soil moisture tension at 50-75 cbar, i.e. 21% ± 2.3% of soil humidity, the highest water productivity in the crop can be reached. |
