    Evaluation of two doses of gibberellic acid in the productivity of tree tomatoes (tamarillo) in the four lunar phases, Pichincha Province, Czech Parish ". The objectives in this study were to determine what dose of gibberellic acid provides increased performance. Determine which of the lunar phases help productivity and tree tomato Perform economic analysis benefit / cost. This research was carried out on the property of Mr. Segundo Guaman Silva is located at 500 m, 26 km of the waterway to Nor.-West of Quito in the parish of Czech Lalagachi Barrio Bajo. The factors studied were Factor A (dose of gibberellic acid) and Factor B (Moon Phases) A RCBD with a factorial arrangement was used 2x4x3repeticiones I; the tests that were performed were: Tukey test 5% to compare averages AxB treatments; Correlation Analysis and Economic Analysis Simple Regression and cost benefit. The main results were: Best performance of tree tomatoes in open fields was obtained with the application of 2 g / l gibberellic flowering (A2) with 20.3 Kg / plot acid. Waning Moon stage (B3); It was the most suitable for the cultivation of open field tomato high yield of 21.6 Kg / plot, as top bioclimatic conditions existed for cultivation. In the interaction of these factors were dependents; obtaining the best response performance in the T7 (A2: B3) with 24.4 Kg / plot. The increased performance variables were: number of flowers per inflorescence; Number of fruit, fruit equatorial and polar diameter length of the fruit. The variable that was significantly reduced performance bioclimatic severe drought conditions prevailing in the area. Economic analysis shows that the T7 (A2B3) treatment showed a CR / B of $ 1.09 and RI / C 9 cents, ie the farmer earn 9 cents for every dollar invested
