| Abstract | ||||
| This study was undertaken during 2015 and 2016 seasons to throw some lights on the effect of two amino acid sources namely “Vegetamine” (24.8% free amino acids + 5.5 % N) and Amino green (15% amino acids + 2.9% Fe, 1.4% Zn and 0.7% Mn) each at 0.05 to 0.4% on some growth aspects, vine nutritional status, berry setting %, yield and berries quality of “Superior” grapevines. Treating the vines three times with “Vegetamine” each at 0.05 to 0.4% caused an appreciable promotion on some growth aspects, leaf pigments and nutrients, berry setting %, yield and berries quality over the check treatment. A gradual promotion on the investigated parameters was observed with increasing concentrations of each source of amino acids. All the studied characteristics were unaffected with increasing concentrations from 0.2 to 0.4%. Using Amino green source was materially superior than using the other source of amino acids namely “Vegetamine” in improving growth, vine nutritional status, yield and berries quality. Accordingly, treating “Superior” grapevines three times with amino acids in the source of Amino green at 0.2% gave the best results with regard to yield and berries quality. | ||||
