| Abstract | ||
| The experiments were Carried out in Biahmu Village at Al-Fayoum Governorate, Egypt during the two winter seasons of 2018/2019 and 2019/2020, on wheat crop to (cv. Gemmiza 11) evaluate the traditional surface irrigation system "TSIS" and the improved surface irrigation system "ISIS"(terrace), under laser leveling with two slops (S1≈ zero% and S2 ≈ 3%). The evaluation parameters included; reduction in land loss "LL", the roughness coefficient of marwa-walls, water efficiencies (i.e., water conveyance efficiencies "WCE", water application efficiencies "WAE" and water storage efficiencies "WSE"), yield productivity "Yp", total applied water and water required, irrigation water productivity "IWP" and times of water advance, recession and opportunity. The results concluded that improving traditional marwa, led to reduction in land loss by 49.46% from the area of marwa, and "WCE" increased by 83.17% in improved Marwa "IM" the compare to Traditional Marwa "TM. It was observed that on the efficiency of water added to the field irrigated by "TM". The highest level of water productivity (1.79kg wheat/m3 water) was achieved in "IM" at a level of 3%. Advanced time "T.Adv" (min) decreased at 50, 50.77, 27.6, 20.75, and 17.17% and 30.9, 40.51, 22.8, 10.89 and7.05% for "TL and IL" by sloping to "S2". | ||
