ABSTRACT
A combination of physical and chemical methods can accelerate the reclamation process. This study was undertaken to investigate the effect of tillage implements in combination with the chemical amendments on the reclamation of saline-sodic soils. Subsoiler, chisel plough, disk plough and narrow-tine cultivator were employed. Subsoiler is found to be the most effective tillage implement for the reclamation of saline soils. Wheat emergence was maximum in sub-soiled plots followed by chisel plough, disk plough and cultivator. ECe decreased from 29.60 to 4.75 dS m-1 (85%), pH 8.1 to 7.43 (8.27%), ESP 115 to 18 (84.34%), and SAR 92.21 to 13.92 (84.90%). The trend of ECe, pH, ESP and SAR was almost reversed after the treatments. The reclamation rate was greater with 75% gypsum applications than that of 50%.
