Abstract
A field experiment was conducted at the Experimental Farm of Indian Oil Corporation Limited, Mathura Refinery, Mathura (India), to study the effect of treated wastewater in comparison with ground water on four cultivars of wheat on the basis of growth, yield and grain quality. It was noted that wastewater increased all growth and yield parameters. Soil irrigated with wastewater showed no significant changes in pH, total organic carbon, calcium, water soluble salts, cation exchange capacity and SAR. Treated refinery wastewater met the irrigational quality requirements as its physico‐chemical characteristics were within the permissible limits. Wheat cultivar HD‐3077 performed best.
