Přidat tag | Shrnutí: | Coffee is recognized globally as a crop of significant economic importance, particularly for small farmers who rely on its production. In the province of Loja, coffee has gained both national and international acclaim due to its high quality, especially that which is grown at high altitudes. In this context, it is essential to implement new technologies that not only enhance productivity but also promote environmental conservation. The objective of this research was to evaluate the development of coffee cultivation in a three-year-old shaded plantation using various organic fertilizers at the Zapotepamba Experimental Farm of the National University of Loja. The study employed a completely randomized block design, which included five different treatments: Azolla bocashi (T1), pollinaza bocashi (T2), Nutrisano (T3), Eco fertilizer (T4), and a control treatment (T5). Each treatment was replicated three times, resulting in a total of 15 experimental units. Several variables were evaluated, including plant height, stem diameter, leaf area, chlorophyll content (measured with the SPAD index), stomatal conductance, stomatal density, and stomatal index. At 120 days after application (DDA), the pollinaza bocashi and Azolla bocashi treatments showed the best results compared to the other treatments, showing the highest averages in all the variables evaluated, both in terms of growth and physiological aspects, surpassing the commercial fertilizers and the control. The findings of this study indicate that using organic fertilizers positively affects the development of coffee crops, particularly the Castillo variety. This practice enhances key growth and physiological variables, underscoring the importance of organic fertilization for optimizing production and ensuring the sustainability of coffee in the region. |
