Abstract

Agricultural use of domestic waste water is a cheap way of its disposal as it is rich in organic materials and plant nutrients (N, P, K, Ca, Mn and Zn). Use of domestic waste water in agriculture may contribute considerable to alleviate the pressure in using fresh water resources. The present study has been carried out to study the effect of combined sewage and industrial effluent on rice crop. The observations revealed insignificant (p>0.05) stimulatory effect on shoot length, root length, no. of nodes, no. of leaves, no. of grains on panicle, dry wt. of whole plant, dry wt. of panicle and dry wt. of grains during Ist year study period and root length, no. of nodes, no. of leaves, dry wt. of whole plant and avg. wt. of grains during 2 nd year study period. Whereas significant stimulatory effect was observed on avg. wt. of grains during 1 st year study period and shoot length, no. of grains on panicle, dry wt. of panicle, dry wt. of grains during 2 nd year study period.
