Abstract
The present study focused on evaluating the impact of application of sugar industry treated wastewater effluent on Sugarcane growth comparing at two experimental farms, one irrigated with the effluent and the other with bore well water, over a period of 11 months (March 2010 to January 2011).The result indicated a significant increase in growth pattern, plant height, shoot diameter, number of leaves and nodes, and biomass of the saplings that was irrigated with the effluents compared to that irrigated with bore well water. The growth parameters showed close relationship with the nutrient contents of treated industrial effluent and bore well water, the former being characterized by relatively higher pH, electrical conductivity (μs/cm), total suspended solids (TSS), sulphate, biochemical oxygen demand, chemical oxygen demand, nitrate and phosphate, and heavy metals—Cu, Pb, Cd, Zn and Mn (mg/l) compared to that of bore well water, indicating profound influence of nutrient rich sugar industry effluent on the plant growth. Higher biomass in sugarcane saplings resulted with irrigation of the effluents compared to that irrigated with the bore well water.
Highlights
Emerging trends of agricultural automation, and reclaimed and treated industrial effluent irrigation over stresses the agricultural land resources through their excessive micro element contamination [1]

Analyses of water quality parameters such as pH, electrical conductivity, suspended solids (TSS), Biochemical Oxygen Demand-5, Chemical oxygen demand, nitrate nitrogen, sulfate, phosphate and heavy metals (Cu, Pb, Cd, Zn and Mn) of sugar industry treated effluent and bore well water used for irrigation of sugarcane saplings showed that the average concentrations of each of the above water quality parameters of treated effluent were higher than those of the bore well water (Table 1)
Summary
Emerging trends of agricultural automation, and reclaimed and treated industrial effluent irrigation over stresses the agricultural land resources through their excessive micro element contamination [1]. Rising trends of using the waste water (industrial effluents) for irrigation has the advantage of pollution removal where the pollutants are partly taken up by the plants and partly transformed in the soil without causing any damage. The potential for adverse health impacts of irrigation with wastewater has been addressed in a number of earlier studies. Effective and appropriate wastewater treatment processes can reduce the health hazards associated with wastewater use. [3] the treated effluent coming through stabilization ponds or conventional treatment plants followed by maturation ponds or sand filtration may be free of pathogens. In India as referred by [4], the significant positive correlation between the growth of the saplings
