Abstract
This experiment was conducted on wheat plant cv. Ipa 95 from the period of 3/12/2004 until 6/5/2005 in Kufa region, Najaf. The aim of the experiment was to study the effect of watering by different salinity water (river water E.C. =3.3 dsm−1, mixed water consist of river water and drainage water at a ratio of 1:1, and drainage water E.C. =6.55 dsm−1) and Zinc spraying as ZnSO4.7H2O at conc. of 2 and 4 g/l. In addition to control treatment spraying was done twice on seedlings at two intervals 65 and 95 days old. The interactions between the two factors were also studied. Vegetative parameters and productivity (i.e. plant height, leaf and tillers numbers, leaf area, shoot dry weight, numbers of fruiting and non - fruiting tillers, the weight of 1000 grain and productivity per unit area were studied. The results were as follow: 1- Vegetative growth parameters and productivity were reduced in plant that grown with drainage water for all treatments. The productivity was reduced from 904.5 to 496.4 kg/D . 2- Zinc spraying significantly affected the growth of vegetative parameters and productivity characteristics. Productivity reduced from 820.0 kg/D. when plants were sprayed with zinc at 4 g/l. conc. to 584.6 kg/D. in control treatment. 3- Watering wheat plant with drainage water with out zinc spraying had a negative effect on vegetative parameters and productivity that reached (438.2 kg/D.). Meanwhile, watering plants and drainage water with zinc spraying gave an important effect in studied characteristics, Productivity increased to 513.5 kg/D. with Zinc at 4g/l. compared with control treatment.
