Desempenho de cultivares de alface sob cultivo hidropônico nas condições do norte de Minas Gerais

Abstract

The hydroponic cultivation is a plant production system in a liquid medium containing a nutrient solution required for development of the crop. Among the species grown under hydroponic lettuce is the highest expression. The objective of this work was to evaluate the phytotechnical behavior of seven lettuce cultivars in hydroponic cultivation, in the semi-arid conditions of northern Minas Gerais. The experiment was conducted at the Institute of Agricultural Sciences of UFMG, Montes Claros, using a completely randomized design with seven cultivars and five replications. Four cultivars were evaluated the curly type (Veronica, Marisa, Cinderella and Roxane), two flat type (summer Baba and Regina) and the American type (Irene), as the number of leaves, stem length, mass of leaves fresh and dry leaves. It can be concluded that to cultivate summer Nanny presented himself as more promising for the hydroponic cultivation to the Northern Region of Minas Gerais.
