Assessment of losses by foliar blight of wheat (Triticum aestivum L.)with reference to tillage option management in plain region of Uttar Pradesh, India

Foliar blight of wheat caused by Bipolaris sorokiniana, Alternaria triticina, Pyrenophora tritici-repintis and Curvularia lunata aregaining importanceespeciallyinNorthWesternand NorthEasternplainZones(NWPZ and NEPZ)ofIndia. The experiment was conducted at main experimental farm N.D.U.A. &.T. Kumarganj, Faizabad (U.P.) by taking two wheat varieties i.e. NW1014 and HUW 234 and three tillage systems i.e. zero tillage, FIRBS (Furrow Irrigated Ridged Bed System) and Conventional tillage. Zero till resulted in higher mean per cent disease index (PDI) with variety HUM-234 in the first and second year, respectively, of 72.50 and 69.44 per cent. Under conventional tillage, however, highest yield and yield contributory characters recorded with combination variety NW-1014 during both the years. Conventional tillage with 41.30 and 42.50 q/ha had non-significantly higher yields in first and second year over zero tillage (38.75 and 40.60 q/ha).
