| Abstract | ||
| This study was carried out during 2015 and 2016 seasons to investigate the effect of different concentrations and frequencies of application (once, twice or thrice) of selenium and some vitamins (B complex, A and D) on growth, vine nutritional status, yield and berries quality of Superior grapes. The treatment of grapevine once, twice or thrice with a mixture of selenium at 25 to 100 ppm as well as vitamins B complex (B1 + B2 + B6 + B12) at 250 to 1000 ppm and vitamins A and D at 25 to 100 ppm caused a remarkable promotion on all growth aspects, pigments and nutrients in the leaf, yield as well as both physical and chemical characteristics of the berries over the check treatment. Conclusively, subjecting superior grapevines grown under Minia and the resembling conditions twice with a mixture of Selenium at 50 ppm in combined with vitamins B complex (B1+B2+B6+B12) at 500 ppm, A and D each at 50 ppm was responsible for improving yield and berries quality. | ||
