Evaluación de tres formas de fertilización en el cultivo de mora de castilla (Rubus glaucus Benth)

Abstract

In the Experimental Farm of the National Institute for Agricultural Research "INIAP" located in the Píllaro canton, three forms of fertilization were evaluated on the cultivation of blackberry (Rubus glaucus Benth) was evaluated, where the study factors were: drench application, edaphic application and application combined (drench and edaphic). The experimental design used was a completely randomized design (DCA), with four treatments and three repetitions. The variables evaluated were number of buds per productive branch, number of flowers, number of fertilized fruits, number of harvested fruits, fruit weight, yield, concentration of soluble solids, and fruit firmness. Analysis of variance (ADEVA) and Tukey's significance test at 5% were performed for each variable. At the end of the analysis, it was determined that the best way to apply fertilizers is treatment 3 (T3) drench and edaphic, because in all the variables evaluated it was the treatment that presented the highest values in comparison with the other treatments under study. This is due to the fact that, when applying in both ways, the fertilizers are available for a longer time; when applying in the form of a drench, the plant is fed 24 hours after application and when applying in an edaphic way, the fertilizers are assimilable for 10 days. after the application.
