Sustain Wheat Production and Avoid Saline Water decline by using Stimulation Substances and Foliar Application of Micronutrients under North Sinai Soils Condition

Abstract

To maximize the beneficial effect of using some stimulation substances potassium Fulvate and Yeast along with foliar application of micronutrients on wheat crop productivity and properties of sandy soils under irrigation with saline ground water. Two field trials were conducted during two successive winter growing seasons of 2016/17and 2017/18 at Agricultural Experimental Research Station at Al-Arish, Agricultural Research Centre (ARC), Al-Arish Province, North Sinai Governorate, Egypt. The main treatments were Stimulants substants included four treatments (i. e. control, potassium Fulvate (KFv), yeast (Yst) and KFv+Yst) and the subplot treatments were micronutrients foliar application included three treatments (i.e. control, chelated form (Fe+Zn+Mn-EDTA) and mineral form (Fe+Zn+Mn-SO4). The treatments were layout in split plot design with three replicates. The results indicated that application of (KFv+Yst) with foliar application of micronutrients was the best treatment for vegetative growth traits i.e. fresh and dry weight (FW and DW), plant height (PH), chlorophyll content (Chl) and chemical constituents in above ground parts (N, P and K as macronutrients and Fe, Zn and Mn as Micronutrients) as well as grains yield, while the sodium (Na) content of grains was decreased. The highest values of soil available nutrients were recorded with the treatment of (KFv+Yst) and foliar application with micronutrients in the mineral form. Thus, it could be concluded that, the fertilization with potassium fulvate and yeast along with foliar application of micronutrients in mineral sulfate form was considered the most suitable treatment for obtaining the highest grains yield of wheat plants.
