EFECTO DE BIOESTIMULANTES SOBRE EL CRECIMIENTO EN CUATRO HÍBRIDOS DE PIMIENTO (Capsicum annuum L.)

Abstract

IN THE PEPPER (CAPSICUM ANNUUM L.), AS IN OTHER SPECIES CULTIVATED IN ECUADOR, SYNTHETIC CHEMICAL FERTILIZERS ARE APPLIED INDISCRIMINATELY. AN ALTERNATIVE THAT CAN REDUCE SOIL, WATER, AND ATMOSPHERE POLLUTION IS THE USE OF BIOSTIMULANTS. THE OBJECTIVE OF THIS RESEARCH WAS TO EVALUATE THE EFFECT OF BIOSTIMULANTS (BOVINE MANURE, VERMICOMPOST LEACHATES FROM BOVINE MANURE, EFFICIENT MICROORGANISMS) ON GROWTH VARIABLES (PLANT HEIGHT, STEM DIAMETER, NUMBER OF LEAVES) IN FOUR PEPPER HYBRIDS (QUETZAL, ODÍN, NATHALIE AND CANARIO) UNDER PROTECTED CULTIVATION AND LOCALIZED IRRIGATION CONDITIONS, BETWEEN 2017 AND 2019. A RANDOMIZED COMPLETE BLOCK DESIGN WITH THREE REPLICATES WAS USED IN EACH HYBRID. VARIABLES WERE MEASURED 60 DAYS AFTER TRANSPLANTATION. THE USE OF BIOSTIMULANTS INDUCED SIGNIFICANT DIFFERENCES IN THE VARIABLES EVALUATED. THE DIFFERENCES WERE EXPRESSED IN DEPENDENCE ON THE HYBRID, BUT IN ALL THE HYBRIDS AT LEAST ONE BIOSTIMULANT LED TO VALUES SIMILAR OR HIGHER THAN THOSE ACHIEVED WITH CHEMICAL FERTILIZATION BASED ON NITROGEN, PHOSPHORUS AND POTASSIUM (CONTROL).
