Abstract
Biotic and chemical methods for the reclamation of a calcareous saline-sodic soil were compared under field conditions. Five Treatments viz. control, gypsum@100%GR-15 em, Sesbania (Sesbania aculeata), sordan (Sorghum bicolor X Sorghum Sudanese), and Kallar grass (Leptochola fusea) were employed on a permanent layout for a period of two years..canat water was used for irrigation and leaching. Sesbania and kauar grass werp. found to be potential biotic materials for soil reclamation. These plant species produced substantial biomass and also improved the soil conditions by lowering ECe and SAR of the soil. Efficiency of Sordan was relatively less due to its sensitivity to high temperature and sodicity during germination and early seedling stages.
