| Abstract | ||
| A field experiment were carried out saline soil at the region of Demro Village, Sidi salem City, Kafr El Shiekh Governorate, Egypt, during two successive growing winter seasons of 2018/2019 and 2019/2020. Therefore this study was carried out to evaluate the effect of leaching technique. i.e. uncontinuous process "ULP" and continuous process "CLP" under individual and combined gypsum application rates as a percent of soil gypsum requirements "GR".i.e. 0, 50 and 100 % ( G1,G2 and G3, respectively) and tillage depth .i.e. without "T1", 20 cm "T2" and 50 cm "T3". These treatments were arranged with in the experimental plots in split-split plot at randomized complete block design in three replicates. The effect of the studied treatments on soil salinity, bulk density and hydraulic conductivity as well as productivity on wheat (Triticum aestivum, Masr3) plants were studied. Increasing rate of added gypsum as well as increasing in tillage depth resulted in a significant decrease of both soil salinity and its bulk density while resulted in a significant increase of soil hydraulic conductivity. The high changes of the studied soil properties were observed with ULP technique. In addition straw and grains yields of wheat plants were increased significantly as a resulted of gypsum applications and increase of tillage depth, where the highest yields were found with the combined treatments of GR3 and T3 with ULP technique. The data of this study show the high efficiency of combined amelioration processes in improve properties of saline soil and its productivity of crops compared with the single process. | ||
