Effect of Humic Acid, Compost and Biofertilization on Fruiting of Superior Seedless Grapevines

Year: 2016

Type: article

Abstract: Superior grapevines fertilized with compost, biofertilizers namely (Bacillus megatherium, Bacillus curculanse and Azotoacter Chroococcum), humic acid and two slow release fertilizers namely ( rock phosphate and feldspar ) as a partial replacement of mineral N fertilizers during 2013 and 2014 seasons. Using all substitutes of mineral N fertilizers was favourable than using mineral N alone in enhancing all growth characters, total chlorophylls, nutrients, yield and berries characteristics. Both nitrite and nitrate in the juice were greatly declined in all N management treatments that included the application of all N sources. The best results with regards to yield and berries characteristics of Superior seedless grapevines were recorded on vines that received 60g N, 60g P and 120g K/ vine/ year ( mineral sources) plus compost II ( 40% cattle manure + 60% rice straw ) at 16 kg./ vine+ the three biofertilizers namely Bacillus megatheium, Bacillus circulanse and Azotobacter chroococcum + humic acid each at 10ml./ vine/ year.
