Abstract
Two field experiments were carried out on a newly reclaimed sand soil under drip irrigation system at El Ismailia Agricultural Research Station, El Ismailia Governorate, The research station 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 to evaluate foliar application of anti-transpiration citosan and abscisic acids at rate of 0.0, 5.0,10.0 and 0.0, 15.0, 20.0 mg l−1, respectively at different water requirements 100 and 75% (1125 and 884 m3 fed-1) on nutrients contents in the soil Nutritional status as soil content considerably influenced by soil type, water irrigation system as well as types of hydro-gel at different rate of soil application under study. The results revealed highly significant on macro-nutrients (N, P and K) and micro-nutrients (Fe, Mn and Zn) content in soil throughout the irrigation water 100% applied at drip irrigation system., seeds productivity and nutritional status of peanut plants with increase water use efficiency, taking a full advantage of available water and net benefit of return and create ways to improve drought tolerance of peanut plant under sandy soil conditions. Data obtained showed that: The results obtained of macro-nutrients (N, P and K) and micro-nutrias (Fe, Mn and Zn) content of peanut plants and also that irrigating peanut plants by 1125 m3 fed-1 and application of hydro-gel at rate of 2% with foliar spray of 5 mg l-1 chitosan and 15 mg l-1 abscisic, resulted in remarkable increases macro-nutrients (N, P and K) and micronutrients (Fe, Mn and Zn) content of peanut. Decreasing the amount of irrigation water from 1125 to 884 m3 fed-1 decreased the micro nutrients content. Thus, application of the irrigation water at 100% (1125 m3 fed) accompanied with anti-transpiration chitosan or abscisic acid at low rates were more efficient in term of water use efficiency under sandy soil condition grown with peanut plants.
