Abstract
A pot culture experiment was conducted on a saline soil to observe the effect of leaching on soil properties, chlorophyll content of leaves and dry matter yield of plant tops and roots of sugarcane (Cv. Co-740)• The experimental soil was collected from the farmers' field where sugarcane crop showed severe chlorosis right from the emergence upto the maturity. Plastic pots of 15 litres capacity were filled with 13 kg soil and leached with different quantities of water to create different levels of salinity. The sugarcane plants were grown for 145 days. Leaching of a saline soil with increasing quantity of canal water significantly improved the sugarcane growth as evidenced by increase in the number of tillers per plant and size and weight of the third leaf from the top of the mother plant. The leaf and root-Fe + chlorophyll and dry matter yield of sugarcane increased with the increasing leaching of soil without adversely affecting the soil properties.
