Abstract
The effect of nine different levels of irrigation on yield and yield components of wheat indicated that Uciab-2000 gave 7.0% to 8.8% higher total dry matter yield than Chenab-2000 in 2001-2002 and in 2002-2003, respectively. Crop was irrigated partially or fully i.e. throughout the season including grain growth period increased grain yield by 136.1% due to an increase in the number of ears m2, number of spikelts per ear over unirrigated plants.Irrigation increased the number of grains spike"' over unirrigated treatment by 46-66 % in different seasons. Cultivar differences in mean grain weight were non-significant in both the years.Moisture stress during grain growth period drastically reduced the mean grain weight.The fully irrigated treatments increased mean grain weight by 104.5% in 2001-2002 and 22.0% in 2002-2003 over unirrigated control treatment. Mean harvest index varied from 29.63 % to 31.0%. There was a positive and linear relationship between total dry matter and grain yield.
