Evaluación de un bioformulado líquido en el cultivo de mora (Rubus glaucus benth) en la comunidad San Diego Provincia de Tungurahua

Abstract

This research seeks to explore viable strategies for the implementation of Trichoderma harzianum and Bacillus subtilis as a complementary tool, promoting a sustainable and efficient approach in agriculture. To evaluate a liquid bioformulation in the cultivation of blackberry (Rubus glaucus Benth) in the community of San Diego, Tungurahua province. The experiment was carried out in an already implemented crop of 5 and a half years where it was carried out under a completely randomized block design (DBCA) with three treatments and three replications, each experimental unit consisted of 5 plants of which variables such as number of branches, number of fruits, length and diameter of fruits, fruit weight, soluble solids, plant vigor, pH and economic analysis were evaluated during the execution of the trial, the applications of diammonium phosphate and liquid bioformulated, were carried out with a frequency of 30 days. The results obtained were tabulated in Excel and later processed in the software InfoStat student version 2020 for statistical analysis. Treatment T2 (50% chemical + 50% bioformulated) is positioned as the best option to improve the productivity and quality of blackberry, showing superior results in fruit yield, size, weight and quality of soluble solids, compared to other treatments evaluated in different studies, although T1 (negative control) showed a slightly higher B/C index of 2.65, treatments T2 (50% chemical + 50% bioformulated) and T3 (100% bioformulated) also obtained a significant B/C index, indicating good profitability. It is recommended to apply the liquid bioformulated via soil application for blackberry (Rubus glaucus Benth) cultivation in the San Diego area since higher productivity was observed in the study variables.
