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.
This study was conducted in the vegetable farm/Hort. & land scape Dept./College of Agric. & Forestry / Mosul Univ. to study the effect of two levels of phosphate fertilization, zero, 40 kg P 2 O 5 /Donum, and spraying with three levels of seaweed extract, kelp 40, Zero, 2,4 ml/l in two pea cultivars namely: "Little Marvel and Fabreca". Plants were sprayed twice, the first one at 3-5 true leaf stage, whereas the second after 15 days from the first spraying. Results indicated that phosphate fertilization & seaweed extract showed a clearly effects in TSS, protein percentage of seeds, nitrogen & phosphorus concentrations of leaves, in addition to number of root nodules/plant. Phosphate treatment gave the highest protein percentage (30.08%), while spraying with 4 ml/l of seaweed extract resulted in the highest values of nitrogen, phosphorus concentrations in leaves, and the large number of root nodules/plant. The results revealed also that cultivars varied between them in all parameters studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
