Abstract
Grapes are one of the most important horticultural crops in Egypt. The "ARRA 15" table grape vines variety is one of the most recently produced varieties introduced into Egypt. This study was carried out to show the nature of their growth and nutritional needs as well as their storage behavior under Egyptian environmental conditions during two seasons (2016 and 2017) on grapes vines grown in a private farm at El Sadat City, El-Menoufia Governorate, Egypt. The effect of three treatments i.e. Potassium silicate (KSi), vermicompost tea (by spraying) and a bio-fertilizer (as soil addition). Potassium silicate and vermicompost tea were sprayed on vines grapes either separately or accompanied, while bio fertilizer was added to soil in the presence of spraying of either potassium silicate or vermicompost tea and sprayed tap water (control). These treatments were carried out during three different stages before harvesting. To study the effect of aforementioned treatments on storability of "ARRA 15" variety, clusters of matured grape fruits were harvested and packed in cartons. The results showed that all treatments either alone or in combination reduced weight loss and decay incidence of clusters under our storage conditions. Deterioration rates quality characteristics of clusters and berry softening were decreased compared to untreated clusters.
