Abstract: A target MOTAD model was developed to evaluate tomato Production practices in the Riyadh and Kharj area based on expected net returns and risk. Production practices considered include the traditional system (TRAD), unconditioned plastic greenhouses (GHP), and three types production systems utilizing air-conditioned greenhouses (CGH1, CGH2 and CGH3). Targets to cover total production costs and total cost plus additional profits were modeled. Results indicated that CGH3 is the most profitable on average and had the lowest potential for losses. GHP was intermediate in both average profitability and risks. TRAD had the lowest profitability and the highest risk. CGH1 and CGH2 were not included in the optimal farm plans at any level of target income. Expected net returns and risk (measured as the expected sum of negative deviations of the solution results from targeted income ) are important factors shown to affect production practices chosen by the model.
