The Effect of Various Irrigation Regimes and moisture variations and water infiltration in soil on yield and water use efficiency in soybean (Glycin max)
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 2
Abstract
An experiment was conducted to evaluate the Effects of water infiltration to soil in yield and water use efficiency in soybean (Glycin max) in Langeroud, North of Iran. A was studied split-plot in a complete random block plan with 3 replications in the 2011 crop year. Irrigation management included no irrigation (dryland) and irrigations with 6, 12 and 18 days Intervals. Results of this research indicated that average final infiltration was 9.4 (cm/day) and the highest seed yield values for the irrigation management with 12 day interval were 5125.6 (kg/ha) respectively. The highest water use efficiency based on seed yield in irrigation treatment was in the 12, 18 days interval with 1.59 and 1.76 (kg/m3). Volumetric moisture variations in different depths indicated that the moisture content in upper soil layers such as 0-20 cm and 20-40 cm was less than those of 40-60 cm and 60-80 cm layers which was due to water absorption in the first and second layers by the plant.
