There are several techniques that can be used to increase quality and yield of tomato fruits, such as staking methods, plant training, pruning, fruit thinning and planting density. Thus, the objective of the author in this research was to propose and evaluate the agronomic and economic efficiency of tomato cultivation systems (Viçosa Tomato Growing System) and compare them to the ones currently used. The systems were: Fitilho - plants staked vertically with strings and pruned to one stem, spaced 1.2 x 0.5 m; Bambu 50 vertically staking with bamboo and plants pruned to one stem, spaced 1.2 x 0.5 m; Bambo 60 plants staked vertically with bamboo and pruned to two stems, spaced 1.2 x 0.6 m; Cerca Cruzada triangular staking method and plants pruned to two stems, spaced 1.2 x 0.6 m; Viçosa 20 - plants grown in Viçosa system, spaced 2 x 0.2 m; Viçosa 30 - Viçosa system spaced 2 x 0.3 m; Viçosa 40 - Viçosa system spaced 2 x 0.4 m; Viçosa 50 - plants grown in Viçosa system spaced 2 x 0.5 m. The Viçosa System is constituted by the following practices: inclined planting, plants pruned to one stem, fruit thinning, removal of inflorescences and lower leaves. For economic evaluation, the treatments were individually studied in rows of 30 meters long, which it was quantified the costs of inputs and labor. The main economic indicators used were: Operation Cost, Total Operation Cost, Total Cost, Total Revenue, Gross Margin, Net Margin and Profit.The growing systems did not influence the marketable production per plant, the Viçosa 20 system obtained the highest commercial and large fruit yield, which were significantly higher to all other treatments and there was no reduction in the flavor of fruit. This system has also achieved the best economic results, with 14% of reduction in the unit cost and 223% higher in profitability compared to the locally most used system (Cerca Cruzada). Therefore, the Viçosa 20 system is the most indicated system to grow tomatoes.
