ABSTRACT
This study exposes a comparative analysis between organic and chemical fertilization on pepper (Capsicum annuum L.) in a semi-protected cropping system. To this end, four organic and one chemical treatment were applied. The response variables were plant height, number of leaves, stem diameter (mm) and photosynthetic pigments at 15 and 45 days after transplantation. Analyses were performed considering the difference between the last and the first record (increase). Additionally, the number of fruits per plant, the weight of fruit per plant (g), the length of fruit per plant (cm), the diameter of fruit per plant (cm) and the yield (t ha-1) were also assessed. A completely randomized experimental design with 5 treatments and 3 repetitions was used. For the comparative analysis data was standardized by using the natural logarithm and, as a complement, MANOVA-Biplot was used to obtain groups of variables and determine their correlation with each of the treatments. The results showed that, for the variables under study, organic fertilization does not differ from chemical fertilization. However, yielding was 9% higher when bovine manure vermicomposting leachates were used, which stands out as a viable alternative to reduce the use of chemical synthesized fertilizers.
