“Evaluación del comportamiento vegetativo y productivo de un híbrido del tomate (Solanum lycopersicum L.) a la aplicación de bioestimulantes y fertilización orgánica”

Abstract

THIS RESEARCH WAS CARRIED OUT IN THE PARISH OF PICOAZÁ, PORTOVIEJO, PROVINCE OF MANABÍ. THE MAIN WAS TO EVALUATE THE VEGETATIVE AND PRODUCTIVE BEHAVIOR OF TOMATO (SOLANUM LYCOPERSICUM L.) TO THE APPLICATION OF BIOSTIMULANTS AND ORGANIC FERTILIZATION. A COMPLETELY RANDOMIZED BLOCK EXPERIMENTAL DESIGN WAS USED WITH FIVE TREATMENTS AND FOUR REPLICATIONS, AS FOLLOWS: FOLIAR APPLICATION OF ASCOPHYLLUM NODOSUM, FOLIAR APPLICATION OF SARGASSUM SPP., FOLIAR APPLICATION OF ASCOPHYLLUM NODOSUM WITH SARGASSUM SPP. AND TWO CONTROL TREATMENTS WITHOUT BIOSTIMULANT APPLICATION USING ONLY WATER (ONE USING COMPOST AS FERTILIZER AND THE OTHER WITHOUT FERTILIZATION). THE VARIABLES STUDIED WERE PLANT HEIGHT (CM), STEM DIAMETER (CM), NUMBER OF FLOWERS, YIELD (T HA-1), BRIX DEGREES OF FRUIT, DRY WEIGHT OF LEAVES, STEMS AND ROOTS (G), LEAF CHLOROPHYLL INDEX (SPAD). IN THE VEGETATIVE AND PRODUCTIVE BEHAVIOR OF THE PIETRO HYBRID TOMATO CROP UNDER ORGANIC FERTILIZATION, THE COMBINATION OF THE ALGAE A. NODOSUM AND SARGASSUM SPP. PROVED TO HAVE GREATER EFFECTS ON THE VARIABLES STUDIED. WITH AN INVESTMENT OF 3,832.20 USD APPLYING THE COMBINATION OF A. NODOSUM AND SARGASSUM SPP. ALGAE, A TOTAL GAIN OF 23,350.80
