Abstract
This study was carried out during the two successive seasons of 2015 and 2016 on thirty – nine 8- years old Flame seedless grapevines grown in a private vineyard located at El- Tawfekea village – Samalout district, Minia Governorate where the soil texture is clay and well drained with water table is not less than two meters deep . Vines are spaced at 2.0 meters ( between vine ) x 3 meters ( between rows ) 700 vines per feddan). The selected vines (39 vines ) were chosen as uniform in vigour as possible and devoted to achieve this study. The chosen vines were pruned during the first week of January in both seasons. Spur pruning system using gable shape supporting method was followed.
Under the experimental and resembling conditions , it is recommended to fertilize Flame seedless grapevines with Amino minerals nano technology fertilizers at 0.1 % three times at growth start , just after berry setting and at three weeks later for overcoming irregular berries colouration and improving yield and berries quality of Flame seedless grapevines.
