ABSTRACT
The field experiment was carried out to evaluate the efficiency of 50 and 100% Gypsum Requirement (GR), molasses 35 t. ha-1 and 20 t. ha-1, Farm Yard Manure 50 t. ha-1 and 30 t. ha-1, continuos flooding and drying to ameliorate saline-sodic soils. All the treatments were replicated three times in the Randomized Complete Block Design. The initial pre project soil chemical analysis assessed the area saline-sodic in nature. Salt crust scrapping, deep plowing leveling and water management practices were given prime emphasis in amelioration process. There was significant reduction of pH, ECe, SAR and ESP under each treatment, but, 100% GR followed by 50% GR recorded maximum reduction of pH, ECe, SAR and ESP values respectively. As the sampling depth increased the reduction in the soil chemical values also decreased. Among the soil depths, upper most sampling depth (0-15 cm) was found rapid towards ameliorative process. The relevant field practices were also found effective where continues flooding was ranked first in reduction of pH, ECe, SAR and ESP. the amendments showed maximum efficiency in the soil where upper crust of salts was scraped and drainage system of field was maintained.
