| Abstract | ||
| This experiment was conducted on wheat plant ev. Ipa 95 from the period of 3/12/2004 until 6/5/2005 on Kufa region , Najaf . The aim was to study the effect of watering with different salinity water (river water E.C.=3.3 mlmo.cm−1, mixture water consist of water river and drainage water at aratio of 1:1 , and drainage water E.C.=6.55 mlmo.cm−1) and Zinc spraing as ZnSO4.7H2O at conc. of 2 and 4 g/l . Besides control treatment that was water sprayed on wheat seedlings at two intervals 65 and 95 days old . The interaction between the two factors were also studied on flowering parameters (i.e. spike length , numbers of total flowers , sterile flowers , total seeds , spike dry weight ) ; numbers of fruiting tillers , non - fruiting tillers the weight of 1000 grain and productivity per unit area . It could be concluded that : 1- Flowering growth parameters and productivity were reduced in plant that grown with drainage water for all parameters . The productivity was reduced from 904.5 kg/D when plants watered with river water to 496.4 kg/D when plants watered with drainage water . 2- Zinc spraying significantly affected the growth of flowering 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 . with control treatment . 3- Watering wheat plant with drainag water with out zinc spraying had anegative effect on flowering parameters and productivity that reached (438.2 kg/D.) . Meanwhile , watering plants with drainage water with zinc spraying resulted in an important in studied characteristics , Productivity increased to 513.5 kg/D. with 4g/l. conc. compared with control treatment . | ||
