Evaluación de tres niveles de fertilización foliar con Boro y Potasio en dos distanciamientos de siembra en el cultivo de frejol (Phaseolus vulgaris) en la zona de Babahoyo

VIII. SUMMARY The present experimental work was carried out in the properties of the "Los Ríos" farm owned by Mrs. Pilar Chang Doinauea in the Province of Los Ríos of the Babahoyo canton, located at km 4.0 of the Babahoyo-Guayaquil highway. The area has the following geographic coordinates: UTM 1.8334838, 79.5469193. Height of 7 masl, average temperature of 25 ºC, annual precipitation of 1845 mm, relative humidity of 76% and an average of 804.7 hours of heliophany. The ground is flat topography. Forty-year-old bean seeds were used as seed material. The objectives were to determine the most adequate level of fertilization of Boron and Potassium in the production of beans; evaluate the planting distances according to the fertilization and economically analyze the treatments. The treatments consisted of doses of Boron and Potassium of 1.5 + 0.4; 1.0 + 0.3; 0.5 + 0.2 L / ha and sub-treatments the planting distances of 60 x 40 and 50 x 30 cm. The experimental design divided plots was used, with three treatments (dose of boron and potassium), two sub-treatments (planting distances) and four repetitions. The comparison of the averages was carried out with the Tukey test at 95% probability. All the practices required in the crop for its normal development were carried out, such as soil preparation, sowing, fertilization, weed control, irrigation, pest and disease control and harvesting. The evaluated data were height of plant, number of pods by plants, length and width of the pod, number of grains per pod, yield and economic analysis. Based on the results, it was determined that the fertilizer applications with Boron and Potassium, had a positive influence on the development and production of the bean crop in the Babahoyo area; the highest plant height and number of pods per plant was observed with the application of 0.5 L / ha + 0.2 L / ha of Boron and Potassium with planting distance of 60 x 40 cm; in the long and broad pod variables no significant differences in their averages were detected; Using 0.5 L / ha + 0.2 L / ha of Boron and Potassium with planting distance of 50 x 30 cm, a high number of grades per pod was presented and the highest grain yield, as well as a higher net profit was obtained with the application of 0.5 L / ha + 0.2 L / ha of Boron and Potassium with planting distance of 50 x 30 cm with $ 354.15.
