Abstract

Field experiments were conducted along two consecutive seasons of summer (2013/2014) at private farm, Jabbars village, Itay Al-Barud, Beheira Governorate, Egypt, to demonstrate the impact of alternative furrow irrigation techniques, on maize yield, water saving percentage and crop water productivity in clay soil, using three water inflow rates of 1.14, 1.58, and 1.87 (l/s/furrow). The experiments carried out in a split plot design with three replicates at random procedure. Irrigation system treatments were used as the sub-plots namely: every furrow irrigation (CIM), alternate furrow irrigation (AFI7-d irrigation intervals) and alternate furrow irrigation (AFI14-d irrigation intervals). Three different water inflow rates designated as Q1, Q2, and Q3 represented the main plots. The irrigation performance was evaluated through application efficiency (AE %) and distribution uniformity (DU) parameters. Irrigation water use efficiency (WUE) was estimated, which is related to water management. Obtained results indicated that application of AFI7-d lead to high significant effect between seed yields values and irrigation system treatments, (CIM, AFI7-d and AFI14-d). Shifting irrigation practice from conventional irrigation (CIM) to alternate furrow (AFI7-d) corn grain yields were increased approximately from 8.06 to 9.23 % with an increasing water inflow rates. AFI14-d and AFI7-d alternate furrow irrigation treatments with inflow rate Q3, saved water by approximately about 16.25 and 8.92 %, which represented about 289.2 and 172.6 (m3/year/fed), respectively, from total water applied as compared to conventional furrow irrigation (CIM). Both of water application efficiencies (Ea) and distribution uniformities (DU) values were improved with all irrigation system treatments as inflow rate increases. Highest values of (Ea) and (DU) were ranged between (67.15 and 73.59 %) and (0.8551 and 0.8968) were obtained with alternative furrow irrigation (AFI7-d) with inflow rates Q2 and Q3, respectively, as compared to (CIM). Maize seed yields production with all irrigation system treatments had significant increases with an increasing inflow rates. The same trends were observed for water use efficiencies (WUE) and water productivities (WP).
