Efecto de medios nutricionales con trichoderma harzianum y tiempo de fermentación en crecimiento y desarrollo en cultivo de pimiento.

Abstract

The bell pepper (Capsicum annuum L.) is a highly important vegetable worldwide, with a global production of 36,972,494 tons in 2022. China, Mexico, Indonesia, Turkey, and Spain lead production. In Ecuador, bell pepper is essential and cultivated in various regions, although its production has declined in the province of El Oro due to climatic, anthropogenic, and soil pathogen factors. This study aimed to evaluate the effect of nutritional media with Trichoderma harzianum at different fermentation times on the growth of bell pepper seedlings under normal and water-stress conditions. The study was conducted at the experimental farm of the "Santa Inés" campus of the Technical University of Machala, El Oro. A completely randomized design (CRD) with 19 treatments and 4 replications was used to evaluate the effect of combinations of Potato, Rice Husk, Oat with Molasses, Dextrose, and Trichoderma on the plants. Results showed that, under normal conditions, the most effective treatments were Oat + Dextrose + Trichoderma and Oat + Molasses + Trichoderma. Under water-stress conditions, the most effective treatments were Potato + Molasses + Trichoderma, Rice Husk + Molasses + Trichoderma, and Rice Husk + Dextrose + Trichoderma.
