Abstract
This study was carried out during 2015 and 2016 seasons on Flame Seedless grapevines grown in sandy soil under drip irrigation system at Khatatba district, in Menofia Governorate, Egypt. The produced fruits were stored in cold storage at Faculty of Agriculture, Tanta University, Egypt. The aim of this research is to reduce of nitrogen fertilizer by using vermicompost to improve growth , productivity and post-harvest characteristics of Flame Seedless grapevines. Six fertilization treatments were employed as follows: T1(100% vermicompost+0% mineral nitrogen), T2 (80% vermicompost +20% mineral nitrogen), T3(60%vermicompost+40% mineral nitrogen), T4 (40% vermicompost +60% mineral nitrogen), T5 (20%vermicompost +80% mineral nitrogen) and T6(100% mineral nitrogen) (control). Each treatments was replicated three times, three tree per each.
