Abstract


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 .
