The Effects on Fruit Yield and Fruit Properties of Plant Growth Promoting Bacteria Applications on Some Strawberry Cultivars

This study was conducted to investigate the effect of different plant growth promoting bacteria (Nitrogen-1, Nitrogen-2, Phosphor-1, Phosphor-2, Nitrogen+Phosphor) on yield and some fruit characteristics of three strawberry cultivars (Albion, San Andreas, and Monterey). Among bacteria applications, phosphor-1 gave the highest yield amount with an average of 99.88 g plant-1. The highest yield amount was recorded for San Andreas cultivar (93.02 g plant-1). In fruit number, nitrogen-1 application produced the highest value (3.48 number plant-1). Besides, the highest fruit number was obtained by applying Nitrogen-1 to Monterey cultivar with 4.28 number plant-1. Phosphor-2 among bacteria applications provided the best result in fruit index (30.17 g/fruit). Similary, the highest value of the fruit index was also obtained from San Andreas cultivar with the same application. The best soluble solid content (10.02%) was achieved with Nitrogen-1 application. Among the strawberry cultivars, Monterey cultivar gave the highest level of soluble solid content (10.98%). The highest pH value of 3.97 was obtained for Nitrogen-2 application. The highest pH value of 9.92 was possible with the control group in Albion cultivar. In titrable acidity, the highest value of 0.92% was obtained by Phosphor-2 application. The highest titrable acidity value (1.18%) was achieved by applying Phosphor-2 to San Andreas cultivar. As a result of the study, root bacterium applications are thought to be beneficial in terms of yield and quality
