Impact of foliar application with dry yeast suspension and amino acid on vegetative growth, yield and quality characteristics of Olive
Bashika Olive trees (Olea europaea L.) were sprayed twice at full bloom stage and one month after that one with dry yeast suspension (5, 10g.L-1) and amino acid (1, 2ml.L-1), alone and in combination besides control (spraying with water only) during 2017 and 2018 growing seasons. Results sho...

| Summary: |
Bashika Olive trees (Olea europaea L.) were sprayed twice at full bloom stage and one month after that one with dry yeast suspension (5, 10g.L-1) and amino acid (1, 2ml.L-1), alone and in combination besides control (spraying with water only) during 2017 and 2018 growing seasons. Results showed that foliar spraying of dry yeast suspension at 10g.L-1 with amino acid 2ml.L-1 gave the highest significant value of vegetative growth( leaf area, total chlorophyll leaf content) and foliar spraying of dry yeast suspension at 10g.L-1 with amino acid 1,2ml.l-1 gave the highest significant value of carbohydrate leaf content and carbohydrate shoot percentage in first season and dry yeast suspension at 10g.L-1 with amino acid 2ml.L-1 in second season. Also, results showed that dry yeast suspension at 5g.L-1with amino acid at 1ml.L-1 exhibited increase of fruit weight and fruit flesh weight in both seasons respectively. While, dry yeast suspension at 10g.L-1with amino acid at 1ml.L-1 treatment gave the highest significant average yield per tree-1in first and dry yeast suspension at 10g.L-1with amino acid at 0 ml.L-1 in second season.
Treatment of dry yeast suspension at 10g.L-1with amino acid at 0,1and 2 ml.L-1 gave the highest significant value of fruit protein content in the first season and dry yeast suspension at 10g.L-1with amino acid at 1,2 ml.L-1 in seconed season, Dry yeast suspension at 10g.L-1with amino acid at 1,2 m.L-1 treatment gave the highest significant value of fruit oil content in both seasons respectively and highest value of percentage of unsaturated fatty acids in the first season .
