Abstract
This study was carried out during 2015 and 2016 seasons on 30 uniform in vigour 14 years old Superior grapevines grown in a private vineyard located at Abowan village, Matay district, Minia Governorate where the texture of the soil is clay, well drained and water table not less than two meters deep. All the selected vines are planted at 2.5 x 3.0 m apart (560 vines/fed). The chosen vines (30 vines) were pruned during the first week of January in the two seasons using cane pruning method with the assistance of Gable supporting system. Vine load was 72 eyes for all the selected vines on the basis of six fruiting canes X ten eyes plus six renewal spurs X two eyes. Surface irrigation system was followed using Nile water.
The target of this study was examining the effect of different concentrations and frequencies of application of selenium and some vitamins on (B complex B1, B2, B6 and B12) and Vitamins A & D on growth traits, nutritional status of the vines, yield and quality of Superior grapevines.
Under the experimental and resembling conditions its referable to treat mature Superior grapevines with a mixture containing Se at 50 ppm, vitamin B complex (B1, B2, B6, B12) at 500 ppm and vitamins A & D at 50 ppm twice at growth start and two weeks later for improving yield and berries quality.
