This thesis was carried out in four greenhouses with arc roofs with a base area of 6 m2 and a side height of 2 m in the experimental area of Isparta University of Applied Sciences, Agricultural Research and Application Center. For this purpose, greenhouse with LED lighting (LED), Red-colored (RG) greenhouse, Blue-colored greenhouse (BG) and greenhouses with transparent covering material (TrG) were used as materials. The study was conducted between February and May 2019. In this study, the effects of different color cover material on the development parameters of radish were determined by measuring the temperature, humidity and solar energy values of the greenhouse. In order to do these measurements, sensors are placed in the greenhouses. Solar energy measurements were taken between 10:00-16:00 hours considering sunshine time. Temperature and humidity measurements were recorded for 24 hours. When the values obtained from TrG, BG, RG and LED greenhouses were examined, it was determined that the highest temperature value of the radish plant in the LED greenhouse during the growing period. Average greenhouse indoor temperature values were found to be between 13oC and 16oC in LED greenhouse, between 6.5oC and 15oC in COG, between 6oC and 14oC in BG and between 6.5oC ...
