Abstract
Two Factorial field experiments on wheat (Var. Msr2) wereconducted during two successive seasons (2015/2016 and2016/2017).The factors involved gypsum application (none, 100%gypsum requirements) × organic fertilizer rate (none, 20 m3 fed-1) ×nitrogen fertilizer rates (none, 100 kg N fed-1) × zinc fertilizer rates(none, 5 kg Zn fed-1) × 4 replicates. The soils of the experimentallocations have been clay loam in texture and the mean values of someproperties were ECe = 6.40 dS.m-1, ESP = 18.11 % , pH = 8.30 whichreveals higher effects with salinity and sodicity.The important results could be summarized as follows:1- The addition of gypsum according to soil gypsum requirements (GR)prior wheat cultivation resulted in higher wheat yields as a result ofits ameliorative role in soil-pH; soil-EC; soil-ESP and subsequentlyincreasing the availability of some nutrients.2- Better wheat yields have been obtained by adding organic manure of20 m3 fed-1 compost, as a result of modifying various soil physicochemicalscharacteristics and subsequently increasing most nutrientsavailability.3- Nitrogen fertilization with the recommended rate of 100 kg N fed-1 (asAmmonium sulfate) led to higher wheat yields as compared to nonefertilizedtreatment.4- Zinc sulfate fertilization at rate of 5 kg Zn fed-1 for wheat led to betteryields; where that response is related to native Zn- unavailability dueto higher values of soil-pH and soil- ESP.5- The significant interaction of those variables on wheat yield and wheatgrains-N and Zn concentrations as well as protein content revealed thattheir use efficiencies have been affected with each other. The coadditionsof (GR)×organic manure × N-fertilizer ×Zn fertilizer were344 GENEDY et al.highly beneficial in improving N and Zn nutrition for wheat yield insuch soils.
