Maydis leaf blight caused by Biopolaris maydis is highly destructive diseases of maize crop worldwide including India. Depending upon weather conditions they cause the significant yield reduction ranging from 28 to 91 % in maize crop. Hot and humid conditions preferred by Maydis leaf blight. It is present in all tropical and temperate maize growing regions. Growing conditions creating hot and humid condition are most advantageous for the development of the disease. Under tarai condition of Uttrakhand an experiment was carried out by integrating tillage practices like - permanent raised beds, zero tillage and conventional tillage along with different nutrient management approaches like- RDF, SSNF and Farmer’s practices for the management of maize diseases. Results of present study indicated that conventional tillage followed by permanent raised bed and zero tillage and in nutrient management SSNM followed by RDF management practices were found equally good with respect to disease severity but significantly higher grain yield was recorded in permanent raised beds (5817 Kg/ha) and in conventional tillage (5748 Kg/ha) which was found at par with permanent raised beds whereas minimum yield was recorded in zero tillage (5617 Kg/ha). But significantly higher thousand grain weight was recorded in conventional tillage (306 g) and permanent beds (305 g) which was at par, followed by zero tillage (282 g).
