Biol a base de contenido ruminal y su eficiencia en el cultivo de brócoli (brassica oleracea).

Abstract

This research aimed to evaluate the effect of a biol produced from the ruminal content of the municipal slaughterhouse in Cañar on the growth and development of broccoli (Brassica oleracea). The experimental process was carried out in two stages: first, the production of the biol and the analysis of its physical and chemical characteristics; second, the assessment of the biol's impact on broccoli yield. To achieve this, an experiment was conducted using a completely randomized design, evaluating biol concentrations of 4% (T2), 8% (T3), and 12% (T4), a commercial bio-stimulant (T1), and a control group (T0). The response variables included plant height at 4, 8, and 12 weeks after transplanting (WFT), leaf area, and fresh weight of the broccoli heads. The results indicated that all doses of ruminal content-based boil at various concentrations and the commercial bio-stimulant increased the broccoli’s plant height and leaf area compared to the control group. The T3 treatment significantly increased the fresh weight of the heads at 8 and 12 weeks after transplanting. In conclusion, ruminal content-based biol has promising potential to enhance the growth and yield of broccoli (Brassica oleracea). For future research, it is recommended to complement such studies with a foliar analysis to understand the plant's ability to absorb nutrients available from both the soil and foliar applications.
