Effect of super absorbent hydrogel on hydro-physical properties of soil under deficit irrigation.

Due to water scarcity challenges, efficient management of irrigation water is becoming crucial. Water use efficiency (WUE) involves increasing crop productivity without increasing water consumption. This study was carried out to study the effect of hydrogel, deficit irrigation and soil type on WUE, soil hydro-physical properties and lettuce productivity.

Evaluation of saline and magnetized water on emitter hydraulic performance and clogging in drip irrigation.

The present investigation was carried out at the National Irrigation Laboratory of Agricultural Engineering Research Institute (AEnRI), Dokki, Giza, Egypt. This study was performed to investigate the hydraulic performance and clogging ratio of drip irrigation with magnetized water. Magnetized water was created by transferring water through a permanent magnet connected to a feed pipeline.

Influence of water stress on engineering characteristics and oil content of sunflower seeds.

Knowing some physical and mechanical characteristics and oil percentage of sunflower seeds could be useful for harvesting and processing equipment and activities such as transportation, storage, food production processes and establishing database of this seed. The main aim of this research was to study the effect of water stress during irrigation on seed's properties and quality. For this purpose, a field experiment was done under four deficit irrigation treatments [80%, 60%, 100-80 (100% irrigation requirement ETc to seed formation, and then reduced to 80% until harvesting) and 100-60% (100% ETc to seed formation, and then reduced to 60% until harvesting)] in comparable with full irrigation (100%).
