Impact of time and number of irrigations on quality of table grapes

Abstract

In 1955, the International Organization of Vine and Wine adopted a resolution declaring that grapes suitable for use in its fresh form were a special cultivar. Cultivation of grapes for storage is directly associated with the application of certain cultivation techniques. One of the important techniques is time and number of irrigations, because these factors affect the quality of table grapes. To study these issues, we carried out a test at the farm "Hadji Aleddin fermer”. This farm has 100 hectares of fruit-bearing vineyards. The results of the study showed that high-quality grapes for storage were obtained with Taifi rose after fourfold irrigation: during the bud bursting, before blossom, during the growth of berries and at the beginning of the maturity of the berries. With the increase in the number of irrigations, the size of berries increased, as a result, berry skin thickness was reduced and the quality during the storage deteriorated. Our studies revealed that both less and excessive irrigation can cause poor quality and reduced shelf life of table grapes Taifi rose.
