Effect of Spraying Organic Fertilizer and Grapes Fruiting Eyes Number on some of the Characteristics of Growth and Yield of the Local Cultivar, White Intensity, Yitis vinifera L.

Abstract

This study has been carried out in Iraq, in Erbil province, for the season 2015/2016 to study the effect of spraying organic fertilizer and the number of eyes on the fruiting canes of the local cultivar (white intensity, vitis vinifera) on the characteristics of the vegetative growth and the yield. The results exceed the treatment of spraying organic fertilizer (B2 ) for the characteristics of the vegetative growth length, the leaves' number, the leaf area, the number and the length of the grapes clusters and the grape berries quantity giving 78.87 cm, 24.73 leaves, 130.41 cm2 , 4.00 clusters, 21.72 cm and 85.33 grape berries.cluster-1, respectively. Concerning the number of the eyes, treatment (T3 ) has preceded respecting the characteristics of the vegetative growth, the leaves' number, the clusters' number, the clusters' length and the grape berries' number which are 75.87 cm. 22.59 leaves, 117.26 cm2 , 3.89 clusters, 20.58 cm and 74.11 grape berries.cluster -1, respectively. For the treatments' interference, treatment (B2T3 ) recorded 87.07 cm, 29.80 leaves, 146.67 cm2 , 4.67 clusters, 24.73 cm, 104,33 grape berries.clusters-1, respectively regarding the characteristics of the vegetative growth length, the leaves' number, the leaf area, the clusters' quantity, the clusters' length, the berries quantity.
