Evaluación del efecto de la aplicación de fertilizantes orgánicos y químicos en cacao ccn-51

Abstract

The nutritional management of CCN-51 cocoa crop is key to maintain its production and phytosanitation, for this reason it is necessary to implement alternatives that allow producers to obtain better crops in a profitable and environmentally friendly way. The objective of this study was to evaluate the effect of chemical and organic fertilization on the yield of CCN-51 cocoa crop, using 4 treatments (T1, T2, T3 and T4). A bifactorial design was used with 30 replications in each treatment. The variables studied were; active flower bearings per plant, cobs per plant, healthy cobs, diseased cobs, harvested cobs and seed dry weight in two climatic seasons (warm and cold). Statistical analyses were performed using two-factor ANOVA and Tukey (p-value 0.05). T3 was more efficient according to the means obtained in the variables evaluated during the cold season: number of ears per plant, healthy ears, harvested ears and in the dry weight of 100 seeds, with a favorable increase in fruit set and seed weight, improving crop yield, unlike T4, which showed the lowest mean compared to the other treatments. No significant differences were found in the variable diseased ears. T2 showed the highest level in the dry season in the variable active flower bearings per plant.
