Item Evaluación de dos productos a base de calcio boro en un cultivo establecido de mora colombiana (Rubus glaucus) en el cantón Mocha(2023-09) Tenesaca Shigla, Alex Ismael; Vásquez Freytez, Carlos LuisIn Ecuador, blackberry 1s an agricultural product highly demanded due to its organoleptic properties, since it allows the processing of foods while maintaining 1ts nutritional value and sensory characteristics. However, there 18 still little information on fertilization practices to promote increased productivity. The objective of this investigation was to evaluate the effect of two products based on Calcium Boron in an established crop of Colombian blackberry (Rubus glaucus). The effect of three doses (1.0, 1.5 and 2 g/L) of two calcium-boron sources (Tarafol Beca and Multifrutos) on fruit quality and yield of Andean blackberry plants was evaluated. The highest number of set flowers was obtained with Tarafol Beca with average values of 775.83 and 764.80 flowers/plant when applied at doses of 1.5 and 2.0 g/L. In addition, both the fruit weight and the blackberry yield were affected by the type and dose of the product. The maximum values were reached when the plants were treated with Tarafol Beca at a dose of 2.0 and 1.5 g/L (6.33 and 5.31 tn/ha) and with Multifrutos at a dose of 2.0 g/L (5.35 tn/ha). Finally, no differences were observed in the quality of the blackberry fruit due to the application of Tarafol beca and Multifruto in their different doses in relation to firmness, Brix degrees and polar diameter of the fruit, but in the equatorial diameter. The beneficial effect of calcium boron sources 1n increasing the productivity of this crop was demonstrated.
