Evaluación de diferentes soluciones hidropónicas comerciales, bajo los sistemas ntf y raíz flotante en el cultivo de lechuga (Lactuca sativa)

Abstract

Abstract:The present study was carried out with the objective of evaluating two types of hydroponic solutions (Brand 1 and 2), under two systems of hydroponic production: NFT (Nutrient Film Technique) and floating root in the lettuce culture. Variations were analyzed between solution treatments and hydroponic systems, the variables measured were height, weight or productivity and the cost-benefit ratio of each installed treatment. The experimental design used was completely randomized where each lettuce was considered as a sampling unit. Each system had two replicas in two different times. The results indicate that all the treatments had a similar effect in the different variables evaluated, however, the best treatment with regard to the weight or productivity of biomass was the NTF Mark 1, it is also worth mentioning that the NTF treatments showed better facilities for its management, although, its costs were much higher than those with floating roots, but it is recommended that its economic evaluation must be carried out for a longer period of time, in order to see the effective profitability.
