Abstract

The irrigation water in this district is often contaminated by sewage from residential places and drainage from manufactories. The irrigation water contaminated by sewage from residential places, affects the ripening of rice adversely, through high concentration of nitrogen which it contains and hence causes the occurence of sterile, abortive and opaque kernels, The irrigation water contaminated by drainage from manufactories, deoxidises the paddy soil by various reducing substances contained in it and ultimately does harm to the root of rice plant and is also injurious to the ripening of kernels causing the occurence of opaque and basal-white kernels.
