Effect of Compost and Gypsum Application on Yield and its Attributes of Three Bread Wheat Cultivars As Well As Soil Properties under Two Irrigation Levels

Abstract

Many of soil amendments can be used to reduce the effect of saline-sodic soils on crop production. Accordingly, the main goal of the present study is to evaluate the salt tolerance, growth and yield performance of three wheat cultivars (Shandaweel 1, Sids 1 and Sids 14) to salt stress in Egypt. This research was carried out in a field experiment at the Shandaweel Agricultural Research Station during the two successive growing seasons 2017/2018 and 2018/2019 using Randomized complete block design using strip blot arrangement with three replications where, two irrigation levels (I 1 : 100% and I 2 :120% of field capacity) were allocated in split blocks, four compost and gypsum treatments; control: without application, compost (4 ton/feddan), gypsum(8 ton/feddan) and compost + gypsum) were assigned to the sub plots and three wheat cultivars were allocated in the sub sub plots. The results showed that there is a significant difference between tested wheat cultivars for all studied traits. The irrigation by 120% FC gave the highest significant mean values of all studied traits in both seasons except for number of kernels/spike in the first season. For wheat cultivars, there were highly significant differences for all the studied traits between the studied bread wheat cultivars. Treatment by compost or/and gypsum had significant effect in all the studied traits in both seasons as compared to control treatment. Moreover, the irrigation by 120% FC in the presence of compost and gypsum enhanced soil properties and reduced the salinity effect.

Effect of Biochar Application to Fertile Soil on Tomato Crop Production under Saline Irrigation Regime

“…The materials were air-dried before being sieved through 2 mm holes. The OM (organic matter) content of soil samples was determined by the Walkley and Black approach and pH was tested in a soil/water suspension (1:2.5), whereas EC, main cations, and anions were determined in the saturated soil paste extract [43,44].…”
