| A field experiment was conducted at the farm of El- Senv experimental station (ARC). Domiatta governorate, Egypt in 2002/2003 seasons. This study aims to evaluate the effect of added Gypsum (6 ton fed") or FYM (20mr led") or Gypsum + FYM on some chemical and physical characteristics of the clay soil and on the yield of wheat under the conditions of irrigation with drainage or Nile water. The obtained data revealed that: (1) Wheat grains yield and wheat straw yield significantly decreased because of irrigation with drainage water, but application of any experimental amendment significantly increased them in comparing with the control (not-amended) under irrigation with drainage or Nile water. with the highest increment with a mixture of Gyps + FYM. The beneficial effect of the added amendments was more obvious on straw yield irrigated with drainage water, whereas increasing in relative yield (%) of straw yield was the highest under irrigation with drainage water. (2) Treated soil with FYM or Gypsum either in a single or in a combine form caused improving in EC (dSlm), 0.M % and available P, K, Fe, Mn and Zn {mgfkg} of soil comparing with the untreated soil (control) under irrigation with Nile or drainage water. Generally, the treatment of FYM + Gypsum occupied the first order in improving the previous characteristics (3) Bulk density (80, gmi‘cm'), regardless the type of irrigation water. Decreased with application of different amendments and the highest decrement noted with Gypsum+ f-"YM treatment. While it increased in sub-surfaces layers than in surfaces layers. Total soil porosity (TP %) increased in the two studied soil depths because of application of FYM or Gypsum+ FYM to SOII irrigated with Nile water, but under irrigation with drainage water it increased in soil treated with solo gypsum in comparing with the corresponding values in the untreated control soil. Total soil aggregates (%i values, under irrigation with Nile water, generally increased in the surface and sub-soil layers of soil treated with any used amendments in comparison with the corresponding values of the control treatment. While, in soils irrigated with drainage water, their values decreased only in sub-soil layers because of amendments application comparing with the control treatment. | ||||
