Abstract
The present study showed that rice mill effluent had an adverse effect on growth and development of tomato plant at higher concentration, but in lower concentration there is no toxic effect on general welfare, rather it has some beneficial effect on the growth and development of the crops in certain concentration of effluent. The continued importance of tomato (Lycopersicon esculentum Mill.) as a vegetable and salad commodity is reflected by the large volume of research on virtually all aspects of the crop. In the present paper, the physicochemical characteristics of rice mill wastewater were measured prior to field experiment. The wastewater revealed an alkaline pH (7.51) with low concentration of DO (1.2 mgl-1), nitrate (0.76 mg l-1), phosphate (18.1 mg l-1) and sulphate (37.66 mg l-1) and moderate concentration of COD (513 mg l-1), chloride (121.5 mg l-1) and TDS (562.63 mg l-1) and high concentration of total suspended solids (536.66 mg l-1) and BOD (313.7 mg l-1). In our present investigation, beneficial impact on general welfare of the tomato plant was gradually increased with increasing the concentration of the effluent up to 100 ppm.
