Abstract
Deficit irrigation is one of the most important methods of management of irrigation to save irrigation water without much damage to plants, the aims of this researches to management the water irrigation of cotton crop in Nineveh province–north of Iraq, RCBD experiment was conducted in the field of agriculture technical college, in Mosul city, during the season 2011 for the cultivation of cotton, cocker-310, using different irrigation levels 100, 75, 50, and 25% of field capacity with drip irrigation method, The results shown, there are significant different at 0.01 for treatment 100% full irrigation for plant height, seed index, lint index, lint percentage, and lint cotton yield, reached 107.4cm, 9.78g, 4.98g, 33.7% , 477.13kg/h respectively. There are significant differences for level 100% at 0.05 for seed cotton yield was reached 1443kg/h. The trend analysis for irrigation levels shows there is linear function between amount of irrigation and plant height , lint percentage, seed cotton yield and lint cotton yield kg/h, quadratic function between irrigation amount and lint index, cubic function between irrigation amount and seed index
