Evaluación de dos bioestimulantes en el cultivo de fresa (Fragaria annanasa) variedad albión californiana

Abstract

The research work was carried out on the property of Ing, Fernando Salguero, located in the province of Tungurahua, Tisaleo canton, with geographical coordinates corresponding to 1 ° 21´0´´ South latitude and 78 ° 40´0´´ longitude West, with an altitude of 3156 meters above sea level, with the objective of evaluating the application by venturi of three concentrations of Quantum 20cc, 30cc, 40cc and Organihum flower 20cc, 30cc and 40cc, for the expression of the characteristics of the strawberry. The treatments were six without witness. The design was divided into a divided plot divided into random blocks, the main plot being biostimulants and sub plots with three repetitions. The analysis of variance and significance tests of Turkey at 5% was performed. The economic analysis was carried out under the cost benefit ratio methodology. The application of the biostimulants Kuantum (P1) and Organihum flower (P2), were very effective within the trial to express the characteristics of the strawberry. Both products performed similarly, achieving almost equal results, in all the variables that were evaluated. With the application of Organihum flower in a dose of 30cc (P2D2), the best results were obtained, achieving the best size of the strawberry fruit (6.40 cm) ideal size for a first category strawberry; an optimal pH of the strawberry fruit (5.00) that is to be balanced according to the optimum pH of the strawberry; fruit firmness (0.60 kg / cm2) demonstrating that the biostimulant acted effectively; broad concentration of soluble solids (Brix degrees) which was (12.80 Brix); a hanger duration of (6 days); and a very profitable yield of (23.81 t / ha). From economic analysis it is concluded that, the Organihum flower treatment with a dose of 30cc (P2D2), reached the highest cost benefit ratio of 1.25; where the net benefits obtained were 1.25 times what was invested.
