This study was carried out in the temperature controlled greenhouse of Erzurum Atatürk University Plant Production Application and Research Center in 2017 to investigate the effects of the use of organic fertilizers in strawberry cultivation in greenhouse conditions on biochemical content of fruits. As a vegetable material, first class frigo seedlings belonging to Albion strawberry variety were used. The experiment was designed with 3 replications according to the experimental design and 30 plants in each replica. Kokopit was used as the growing medium in the experiment. Roa Plus Organic Fertilizer was applied to the plants outside the control plants every two weeks at the recommended dose. Four months after the experiment, the first specimens were taken and 3 colony bumblebees were placed in the greenhouse. After 1.5 months, samples were taken and compared. In the study, the content of TSS, total sugar, vitamin C, Malic acid, pH and Titratable Acid were determined. As a result, it was determined that most of the parameters examined in the fruits of both control and organic fertilizer application with the activity of Bumblebee bees. [ABSTRACT FROM AUTHOR]
