| Abstract | ||||
| Due to the importance of improving salt-affected soils in Egypt's agricultural security policy, a field experiment was conducted in the winter of 2021/2022 at Kom Abou-Khallad village, Nasser district, Beni-Suef Governorate, Egypt, aiming to determine the impact of various amendments with various two-tillage systems on certain properties of salt-affected soils, as well as the growth and productivity of fodder beet (Beta vulgaris L.). Different amelioration techniques were applied using soil conditioners (natural gypsum, cement dust modified, phosphogypsum, and filter mud) that were carried out under two tillage systems, namely, shallow and deep (subsoil). The results show that subsoil tillage decreases bulk density and penetration resistance by about 7.75 and 13.6% and increases total porosity and hydraulic conductivity by about 7.31 and 7.7% over shallow tillage, respectively. increase available water by about 1.51 %, reduce pH, decrease ECe by about 12.47 %, decrease ESP by about 10.44 %, and increase soil organic matter by about 6.25 %, as well as increase the fresh yield of roots and shoots by about 22.75 and 34.32 %, respectively. The corresponding increases for dry roots and tops yields were 21.75 and 22.45%, respectively, for the nutrient uptake of fodder beet plants. The relative increment in total N, P, and K uptake reached 28.58, 29.27, and 30.87%, respectively. Treated fodder plants cultivated in salt-affected soil with soil conditioners, especially filter mud, at a rate of 18 mg ha-1 resulted in a decreased hazardous effect of salinity by improving soil properties, which consequently increased its productivity. | ||||
