Abstract
The aim of this investigation is to study the effect of two sources of compost tea (A: compost tea of rice straw and B: compost tea of pruned wastes) with or without citric acid on bud fertility percentage, vegetative growth, leaf mineral content, physical and chemical characteristics of clusters and berries, yield, wood ripening and weight of pruning wood. Obtained results are as follows: 1. The obtained results showed that compost tea B alone (T3) or combined with compost tea A (T4) significantly increased bud fertility%/vine as compared with that of control in 2 seasons of study. 2. It was cleared that the combination between two kinds of compost tea A & B combined with citric acid, (T7) (compost tea A + compost tea B + citric acid)gave the highest significant increase in shoot length and internodes diameter and gave the highest values in leaf chlorophyll content as compared with that of control as mean of two seasons of study. 3. The data indicated that the most effective treatment, which gave the highest significant increase in N, P and K% in leaf petioles was obtained from (T7) in both seasons of study. 4. It was cleared that T5 (compost tea A + citric acid) gave a significant increase in yield/vine followed by, (T7) as compared with that of control in both seasons of the study. 5. (T7) gave the highest significant increase in total and reducing sugars% and gave the highest significant increase in total anthocyanin content in berry skin while gave the highest significant decrease in phenol content in berries as compared with that of control in both seasons of study. 6. It was cleared that T7 gave the highest significant increase in N, P and K% and NO2 and NO3 content in berry juice as compared with that of control in both seasons of the study.
