This paper investigates the importance of various environmental factors that have a strong influence on strawberry yields grown in greenhouse using various pattern recognition methods. The environmental factors influencing the production of strawberries were six factors such as average inside temperature, average inside humidity, average CO2 level, average soil temperature, cumulative solar irradiance, and average illumination. The results of analyzing the observed data using Dynamic Time Warping (DTW) showed that the most significant factor influencing the strawberry production was average inside humidity, while it was found that average illumination was the lowest influential environmental variable. In addition, an increase in the level of co2 significantly affects the decrease in strawberry yield. Therefore, in order to increase the harvest of strawberries cultivated in the farms, it is necessary to manage the environmental factors such as thoroughly controlling the humidity and maintaining the concentration of CO2 constantly by ventilation of the greenhouse.
