Abstract
This study was carried out during the two successive seasons of 2016 and 2017 on 84 uniforms in vigour 10- years old Superior grapevines grown in a private vineyard located at El- Hawarta village – Minia district, Minia Governorate where the soil texture is clay and well drained since water table depth is not less than two meter (Table 2). The chosen vines are planted at 2x 3 meters apart. Cane pruning system was followed at the first week of Jan. leaving 84 eyes per vine (on the basis of six fruiting canes x 12 eyes plus six renewal spurs x two eyes) with the assistance of Gabel shape supporting system. The vines were irrigated through surface irrigation system using Nile water.
This study aimed to elucidate the effect of NPK fertilizers applied via nano technology versus using the traditional methods on some vegetative growth aspects, vine nutritional status, yield and berries characteristics in Superior grapevines grown under Minia region conditions.
Under the present and resembling condition, it is suggested to fertilize Superior grapevines grown under Minia region conditions with N at 10 g / vine, P at 14 g / vine and K at 40 g/ vine via nano-technology as a replacement for traditional methods for improving yield and berries quality and at the same times reducing fertilizer costs and environment pollution and enhancing net profit from 28500 L.E. in traditional methods to 37600 L.E in nano fertilization system.
