| Abstract | ||||
| Two field experiments were carried out on a newly reclaimed sand soil under drip irrigation system at Ismailia Agricultural Research Station, Ismailia Governorate, Egypt located between Latitude 30° 35' 30" N, Longitude 32° 14' 50" E and Elevation 3 meters, and cultivate with peanut plants as summer season (Arachis hypogaea, Giza 5 c.v) during the agricultural growing season of 2016 and 2017 at rate of 50 kg fad-1. To evaluate foliar application of some anti-respiration (chitosan at rate of 0.0, 5.0, 10.0) and (abscisic acid at rate of 0.0, 15.0, 20.0 mg l−1), as foliar spray afternoon at three times after three weeks from sowing (30, 60 and 90 days) and applied hydrogel at rate of zero, 2 and 3% as soil application under two irrigation water requirements 100 and 75% (1125 and 884 m3 fad.-1). Results obtained showed that: It was clear that applied irrigation water requirements at rate 100% with foliar spray of 5 mg l-1 chitosan and soil application of hydro-gel at rate of 2% on both seed yield of peanut and contents of macro-nutrients (N, P and K) and micro-nutrias (Fe, Mn and Zn) for seeds and high water use efficiency at irrigation water requirements 100% accompanied with foliar application of abscisic acid and hydrogel at rate of 3%.
