Abstract

The limited availability of water, which is becoming more and more severe worldwide, demands a more efficient use of water in agricultural production. The closed hydroponic systems make a more efficient use of water, where the surplus nutrient solution is recovered, regenerated and reused in the same crop. The objective of this research was to know the effects on production and fruit quality with six percentages of drainage (%D): 25, 30, 40, 45, 55 and 60% D of the nutrient solution in a tomato crop. Pots with a fine pearlite substrate previously used were used. The research was carried out in 2016 in the Academic Unit of Agronomy of the Autonomous University of Zacatecas. The number, size, weight and yield of fruits, water productivity and fruit quality (electric conductivity, hydrogen potential, soluble solids, acidity and juice maturity index) were measured in two stages of production. There was a significant difference in yield and quality for treatments 3 and 4 and 1 and 2 respectively. With % D of 40% higher yield was obtained, but with 25% of drainage the content of salts and sugars in fruit was increased and the highest productivity is obtained with respect to the other percentages.
