Abstract

In order to innovate an aquaculture production system that increases water productivity, an experiment was conducted at an aquaculture farm in Saltillo, Coahuila, where lettuce cultivation was established under a hydroponic system called floating root, under shade net conditions and foliar fertilization, agronomic variables were analyzed: root length, stem thickness, height, fresh weight, number of leaves, foliar area and crown diameter in four different treatments and different indicators of profitability were analyzed: net present value, internal rate of return (TIR), cost-benefit ratio and return on investment, to determine the economic feasibility of the system, so, the objective of this research was to determine the agronomic yield and economic profitability of the flouting root lettuce production system under shade net conditions and foliar fertilization. Results obtained in agronomic yield variables showed increases in height, fresh weight, number of leaves, foliar area and crown diameter compared to their absolute witness of 41.77%, 113.9%, 30.43%, 155.92% and 22.22%, respectively. The profitability analysis shows favorable results for additional investment. This research demonstrates the economic viability and an improvement in agronomic productivity of floating root lettuce under shade net conditions and foliar fertilization.
