Abstract
During 2014 and 2015 seasons, Superior grapevines were fertilized with the recommended N (60 g N/vine/year) via 40 to 80% mineral N besides 20 to 60% plant compost enriched with yeast (Saccharomyces cerevisiae), blue algae (Spirulina platensis) or bacteria (Azotobacter vinelandii) each at 5 to 15 ml/vine/year. This study focused on the impact of these treatments on growth aspects, leaf total chlorophylls, and nutrients (NPK), yield as well as some physical and chemical characteristics of the berries.Using the recommended N via 60 to 80% mineral N plus 20 to 40% plant compost enriched with 5 to 10 ml/vine/year yeast, algae or bacteria materially was superior to using N as 100 % mineral N alone or 40% mineral N plus organic and biofertilization in improving growth, vine nutritional status, yield and berries quality. The best microorganisms in this respect was bacteria (Azotobacter vinelandii) followed by algae. Yeast ranked the last position in this respect. There was a gradual promotion on berries quality with reducing inorganic N from hundred to 40% and at the same time increasing the percentages of plant compost from 0.0 to 60% and levels of the three strains of microorganisms from 0.0 to 15 ml/vine/year.Supplying Superior grapevines with N (60 g N/vine/year) through 60% mineral N plus 40% plant compost enriched with Azotobacter vinelandii at 10 ml/vine/year is suggested for improving production and berries quality.
