English Abstract

This investigation was carried out during growing season of 2014-2015 on six years old apple tree cv.

Xank (Malus dumestica Borkh) 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), sheep manure application at three levels (0, 4 and 6 kg.tree-1), and compost application at levels (0, 3 and 5 kg.tree-1), on some characteristics of apple fruits.

According to obtained results, it noticed that girdling (date 1) was best time for girdling, and the high level of sheep manure and compost (6 kg.tree-1and 5 kg.tree-1) respectively.

The interaction between girdling (date 1) and 6 kg.tree-1 sheep manure give high yield.

Moreover, the interaction between girdling (date 2) and 5 kg.tree-1 compost increase fruit set and tree yield.

The superior combination was among (girdling (date 1) + 6 kg.tree-1 sheep manure + 5 kg.tree-1) which cause to improve all studied parameters except number of fruit.
