The objective of this experiment is to study the effect of different nozzles (fogger, mist and mini sprinklers), irrigation periods (30sec, 60sec and 90sec) for (2hr,4hr and 6hr) respectively and seed thickness in the trays (0.5, 1.0 andl.5 cm) on barely sprouts produced hydroponically. Measurements were taken for every production unit (WUE, yield/tray, yield/kg seed, protein %, fibers%). Data showed that using Jogger gave the highest CU%, DU% ,water use efficiency, yield/kg seed, protein %, fiber % and carbohydrates %. On the other hand, data illustrated that using 0.5 cm seed thickness recorded the highest yield/kg seed, protein %, fiber % and carbohydrates %. Concerning using 30 sec/2hr recorded the highest water use efficiency, yield/kg seed, protein %,fiber% and carbohydrates%. Finanv. from the overall results it can concluded that using 0.S.rcm seed thickness irrigated 30 sec/2hr with Jogger recorded the highest tested parameter UR - http://nile.enal.sci.eg/EALE/2015/MJAE/3215/2/589.pdf ER -
