EFFECT OF EYE NUMBER LEFT AFTER PRUNNING, SPRING WITH CALCIUM NITRATE, ARGENINE ACID AND UREA ON GROWTH, YIELD AND STORABILITY FEATURES OF THE FRENCH GRAPE (Vitis vinifera)

Abstract

This study is carried out in a private orchard of vine in Buhriz city \ Diyala province. It aims to study the effect of the buds left after pruning ( the number of eyes left on the vine) and spraying transactions on the growth, crop and storability features of the French vine. includes studying, namely: vine load levels (20, 32, 40 and 52) eyes vine-1 × (calcium nitrate with concentration 20 g l-1 and arginine acid with concentration 0.2 g l-1 and water and urea with concentration 2.5 g l-1 ). The comparison sample is sprayed with distilled water and storage period. The crop is put in bags of polyethylene, 16 holes and the diameter 0.5 Cm2 for each kilogram and the capacity 3Kg. These bags are stored in a refrigerator at 4± Cº in 14th of July, 2013 for two months. The used design is CRD for the storage experiment and by three replications for each sample with weight 3Kg. The comparison is done using LSD at probability level 0.05. The results are as follows: The triple overlap of 20 eyes vine-1 × calcium nitrate exceed in many features at the beginning of storage period except percentage of weight loss and total spoilage of fruits. The highest recorded values for these features is between interaction level of 20 eyesvine-1 and the comparison after the storage.
