Competição de cultivares de alface romana no outono e primavera no município de Boa Esperança - MG

Abstract

Lettuce (Lactuca sativa L.) of the Asteraceae family is the most leafy vegetables consumed in Brazil. It is a herbaceous plant, annual cycle and surface roots. Distinguished from other groups by having elongated leaves, consistent with protruding ribs and forming fluffy heads. The cultivation of lettuce occurs predominantly in warm weather stations, especially in winter, however this vegetable is grown throughout the year. Planting in other seasons may favor the incidence of disease and the occurrence of nutritional imbalances, especially under rainy conditions and high temperatures. The determination of the appropriate cultivars and planting a region at different times of the year helps in driving culture, especially if linked to one or more important characteristics such as yield, tolerance to physiological disorders and plant cultivars which form the head. In Brazil, the romaine lettuce is already being produced mainly for the supply of niche markets that seek minimally processed vegetables and ready for consumption.
