| Abstract | ||
| The research aimed to modify the traditional hydrant to suit connect with the newly irrigation systems. Through evaluate the performance of the traditional "HT" and modified "HD" hydrants of the surface irrigation system applied in clay soil at KafrAldoar- El-Beheira Governorate. In summer season 2019 by cultivated the corn variety of S.C 2031. Then, the results concluded that the "HD" is shallow less than the "HT" in Zf and Es but great reduction in cv and α. While it is little increase in pd, UC, DU and Ea. The "HD" can saved advance and recession time about39.02 and 29.46%, respectively, compared with "HT" in 80 m furrow length. As it was observed, the water depth reached the recommended depth for corn plants in both hydrants for most of the length of the line, but the depth when using the modified hydrant was slightly less than the traditional hydrant. The yield and WUS increased by using "HD" about 9.07 and 28.61 % than the "HT". But it decreases the water applied about 15.16 %.The recommendation on this research is the modified hydrant can safe to use and can be generalized in the irrigation net under the surface and newly irrigation systems. | ||
