Heavy metal accumulations after two years of some organic fertilizers and girdling on apple fruit

Azad A Mayi

This investigation was carried out during growing season of 2015-16 on five years old apple tree cv. Xank grown in the orchard at Gavarky, Duhok governorate, Kurdistan region-Iraq. To study the effect of two girdling date (before full bloom and after fruit set), compost application at levels (0, 3 and 5 kg.tree-1) and sheep manure application at three levels (0, 4 and 6 kg.tree-1), on heavy metals accumulation in fruit of apple fruits. According to obtained results, it noticed that girdling (date 2) gave the higher level of Cd, Cu, pb, Zn at season 2015 (0.082, 2.30, 0.78 and 27.74 mg.kg-1) and season 2016 (0.82, 1.62, 0.31 and 9.19 mg.kg-1) respectively, and Compost specially at 5kg. Tree-1 has significantly increased Cd, Cu, pb, Zn at season 2015 (0.076, 2.37, 0.38 and 36.22 mg.kg-1) while, at 2016 (0.073, 1.47, 0.35 and 10.86 mg.kg-1). Sheep manure specially at 6 kg.tree-1 significantly increased the Cd, pb, Cu, Zn at season (0.072, 2.34, 0.83 and 36.1 mg.kg-1), So at season 2016 (0.069, 1.67, 0.33 and 13.34 mg.kg-1). while, the interactions between girdling, compost and sheep manure significantly affected most studied parameters at girdling date two + 5 kg.Tree-1 of compost plus 6kg.tree-1 of sheep manure increased Cd, pb, Cu, Zn at season 2015 (0.121, 2.45, 0.41 and 38.00 mg.kg-1) however, at season 2016 (0.119,2.24,0.40 and 14.43 mg.kg-1) significantly.
