The problems of greenhouses and their production in Iran were evaluated using data based on questionnaire. This part of investigation was related to decision making of greenhouse owners in provinces of Tehran, Isfahan, Kerman, Markazi, Alborz and Fars. Multivariate analysis was used for inferential analysis. Indices were evaluated by sequentially independent variables and 5-step Likert spectrum was used. Also, in regression analyses decision making level was selected as independent variables and each variable which affected the decision making of greenhouse owners was used as independent variable. The results of decision making of greenhouse owners on management of pest control and use of chemical fertilizers were investigated. Results showed that the decisions of greenhouse owners of different cities were not different for using chemical fertilizers, but they made different decisions for pest control. Between number of training courses, distance to market, greenhouse area, type of crop and type of greenhouse cover with decision made by greenhouse owners for using chemical fertilizers were significantly different. Also, significant difference was found between level of education, experience of greenhouse owners, distance to market and type of greenhouse cover, with decision of greenhouse owners for pest control. Finally, the results were discussed and sugestions were made for the decision making of greenhouse owners.
