ANÁLISE PRODUTIVA E SENSORIAL DA ALFACE CULTIVADAS EM SISTEMA CONVENCIONAL E HIDROPÔNICO

Abstract

The consumption of vegetables has increased due to the awareness of the population in search of a healthy diet, especially lettuce (Lactuca sativa L.). The objective of this work was to evaluate the productivity and sensory analysis of lettuce in two cultivation systems, conventional and hydroponic. The experiment was developed in Itauçu-Goiás, in a rural property (Fazenda Água Vermelha). The design used was by completely randomized blocks, where 2 treatments were used and each of them containing 40 replications. Plant height, number of leaves, length of the main vein of the largest leaf, width of the largest leaf, fresh mass, dry mass and sensory analysis were evaluated, such as; vision, touch, taste and smell. The results showed that there was a significant difference in the hydroponic system compared to the conventional one, only the significant difference in the dry mass of the aerial part did not occur. While in the sensory analysis the vision (greener) and taste (sweeter) the hydroponic system stood out. Therefore, it is concluded that the hydroponic system is a sustainable and totally viable production alternative for lettuce producers in general.
