| Abstract | ||
| Pot experiments were carried out using disturbed soil surface samples, collected from the different plots of Bahtim Experimental Station , and mixed with 20 U ci of carrier free 65Zn. Barely plants were grown and harvested after 42 days . The results showed that the dry matter yield , 2n-content and total Zn-uptake values were not affected by different crop rotations, while initial Zn value was increased in soil under 3-year rotation. Zinc content and total zinc uptake were significnatly affected by different inorganic fertilizer treatments , but dry matter yield of barely plants was not significantly affected. On the other hand, native Zn value was increased by farmyard manure addition while it was decreased by inorganic fertilizer treatments. | ||
