| Abstract | ||||
| To evaluate the effect of modified surface irrigation in old land through improving Mesqas (buried pipeline) and Marwas of irrigation systems developer which were chosen to evaluate it in area of about 73 feddan on the field level to achieve sustainable agricultural development and to know the effect of surface irrigation system developer on the properties of the soil and its effect on plants to improve crop yields (productivity) and rationalizing of irrigation water leading to improved agricultural environment. Also the economic evaluation in the field as important indicator in this study which includes the productivity per unit of irrigation water for the most important winter crop (wheat) and summer crop (maize) and the study also includes the technical evaluation in the field in terms of water losses in delivery and distribution for developed Mesqa and Marwa, as well as water and land saving as a result of the use of modified surface irrigation system compared to traditional irrigation surface system. The agricultural land which was saved through using buried pipes instead of traditional Mesqa ranged from about 2.1 % to 3.7 % with developed surface irrigation systems for Mesqa and Marwa respectively. Average conveyance efficiency were obtained as ranged from about 91% and more 98% with developed surface irrigation systems for Mesqa and Marwa respectively and Average conveyance efficiency was about 83% with traditional surface irrigation while the average application efficiencies for irrigation systems developer by Mesqa and Marwa were ranged from about 61.5 % to 77 % and ranged from about 65 % to 84.4 % respectively and it was ranged from about 53 % to 66.4 % under traditional surface irrigation according to type of crop. The percentage of increase in the productivity under developed irrigation systems for Marwa was 2.32% and 3.6% for wheat and 0.2% and 1.38% for maize compared with irrigation systems developer by Mesqa and traditional surface irrigation respectively. The value of (WUE) in improved irrigation systems for Mesqa and Marwa were 1.52 and 1.38 kg/m3 respectively for wheat and it was 1.16 kg/m3 under traditional surface irrigation. The value of (WUE) in improved irrigation systems by Mesqa and Marwa were 1.71 and 1.54 kg/m3 respectively for maize and it was 1.27 kg/m3 under traditional surface irrigation. | ||||
