Efecto del sustrato hidropónico sobre los atributos de calidad fisicoquímica y fisiológica de frutos de jitomate (Solanum lycopersicum var. saladette)

Abstract

Objectives, methodology: In this paper we evaluate the effect of the substrate type on the physicochemical and physiological parameters of tomato fruits (Solanum lycopersicum) type hydroponic saladette. Fourteen hydroponic substrates of mineral origin were evaluated, and mixtures of the same with the aim of selecting substrates that can satisfy the needs or objectives desired by the producer and allowing the consumer to know a fruit with a better quality reflected by its physicochemical properties such as yield, size, colour, total soluble solids (°Brix), titrated acidity, firmness, ethylene and CO2 production. Contribution Substrates such as tezontle, tepezil and coffee husk are favorable in the cultivation of tomato (Solanum lycopersicum) type hydroponic saladette benefiting some of its quality parameters being the most feasible options for the producer and the consumer. Substrates such as the tezontle with compost, tepezil with vermicompost, sugarcane bagasse with compost, coffee husk with vermicompost and coffee husk with compost are other options to consider for cultivation; while the vermicompost, sugarcane bagasse, tepezil with vermicompost, tepezil with compost and sugarcane bagasse with vermicompost, were the least efficient treatments, redicing the fruit quality parameters.
