Greenhouse activities are increasing in the Mediterranean region and constitute a large portion of agriculture. Climatic conditions can be controlled in greenhouse activities. Wind, one of the most important parameters, is less effective inside the greenhouse than outside through natural means. The study was conducted in experimental greenhouses on the Alanya Alaaddin Keykubat University campus. Three experimental greenhouses were 3x12 m in size. The first greenhouse featured a transparent cover material (CG), the second utilized a blue cover material (BG), and the third was equipped with a blue cover material and inhabited by bumblebees (BBG). Following these treatments, parameters such as plant width, length, weight, stem diameter, total yield, marketable yield, average fruit weight, and leaf chlorophyll content were determined. It was determined that the BBG greenhouse achieved the highest yield, plant height, and fruit equivalent diameter values. Furthermore, the BBG variant achieved the lowest fruit firmness values. This is thought to be due to its faster development and faster maturity compared to other greenhouses. Therefore, it has been determined that both the blue color and bumblebees positively affect tomato plant development parameters in the BBG greenhouse. Therefore, we believe that implementing good agricultural practices to achieve higher yields is ...
