Abstract
Rehabilitation of saline–sodic soils is governed by a lot of management schemes which involve mainly addition of chemical ameliorates as gypsum and sulphuric acid "SA". The recent studies recommended the use of practices package that lead to improve soil health and reduce production costs besides increasing soil-water-fertilizer unit uses. Therefore, under saline-sodic soil conditions the current study was planned to compare the effect of gypsum application (75% of gypsum requirements) and sulphuric acid (20% of the applied gypsum) under three levels of N-fertilizer, 70, 90, 110 kg N/fed., in form of anhydrous ammonia "AA" on soil salinity-sodicity status and wheat (Triticum aestivum L., Sakha 93) production. A split block experimental design with three replications was used to evaluate the tested treatments and their interactions. Irrigation water amount during winter growing season was measured to assess water productivity (WP) of wheat crop under various soil treatments. Results showed almost significant effect of soil amendments application and different N-levels and their interactions on the studied soil parameters (ECe & SAR), wheat yield and its attributes, nitrogen use efficiency (NUE), as well as water productivity. In general, Results revealed also that, effect of the concerned amendments on ECe, SAR values, plant characters, NUE and WP was higher than those of N-levels. However, sulphuric acid application resulted in an increase of wheat grain yield, NUE & WP, by about 56% and 25 %, respectively as compared to un-amended and gypsum treatments. With regard to the interaction effect of the applied treatments on the tested parameters results indicated that the highest values of plant parameters, grain yield production, WP and the lowest values of soil salinity/sodicity parameters were recorded with the 110 kg N/fed + SA applications, while, the highest value of NUE was obtained with the combined effect of 70 kg N/fed and SA applications.
