THE RESPONSE OF DIFFERENT IRRIGATION LEVELS TO GROWTH AND YIELD OF DIFFERENT WHEAT (Triticum aestivum L.) CULTIVARS

Response of three wheat varieties (i.e. Punjab-96, Faisalabad-85 and Inqlab-91) to different irrigation levels viz; 1, 2 and 3 irrigations were studied under Rabi field conditions during 200-2001. The wheat variety Punjab-96 produced significantly the maximum number of fertile tillers m -2 , plant height (cm), number of grains spike -1 , thousand grain weight (g), grain yield (kg ha -1 ), biomass (kg ha -1 ) and harvest index (%) among the varieties tested. The plots treated with the highest number of irrigation level produced significantly the maximum number of plants m -2 , plant height, number of grains spike -1 , thousand grain weight, grain yield, biomass and harvest index of variety Punjab-96.
