| Abstract | ||
| This study was carried out in green house of Agriculture College fields. Tikrit University. Using plastic pots 250 gm capacity to evaluate Zn element behavior in soils with different levels of gypsum content 5 % , 8 % , 14 % , 18 %, with two kind of Zn fertilizer, chelate Zn (Zn- EDTA) and mineral Zn (Zn SO4) using three concentrations (10, 20, 40, mg-kg-1) in (Paniecum miliecum. L) plant. After 45 days of growth , plants were harvested and dry matter production was analyzed. The results showed that soils gave the following significant order of dry matter production (18 %, 14 % , 8 % , 5 %) 0.581 < 0.620 < 0.656 < 0.707 and also the same order of Zinc uptake . results also indicate superiority of organic fertilizer (10 < 20 < 40 < mg. kg-1 ) organic fertilizer gets (0.670 < 0.726 < 0.846 gm. Pot) respectively. While mineral fertilizer gets (0.575 < 0.634 < 0.664 gm. Pot) in dry matter characteristic. As concern to zinc uptake according to same serial of concentration levels, organic Zn – EDTA gets (22.83 < 29.21 < 44.66 mg . pot) respectively . | ||
