INFLUENCE OF CULTIVAR AND PLANTING PERIOD ON SALAD CULTIVATED IN ECOLOGICAL SYSTEM

Abstract

Garden lettuce is grown for head and leaves, which are mainly consumed as salads, simple or combined with other vegetables. It is important in nutrition due to its high content of vitamins and mineral salts. It is cultivated in the field, early spring and autumn, as well as in greenhouses and tunnels, to obtain production during the winter-spring or autumn-winter period. Being a species with a short period of vegetation is cultivated in the system of successive crops, before or after a main crop, as well as in associated crops. In temperate climate, salad culture is not practiced during the summer because in long day conditions associated with high temperatures, plants emit floral stems in most varieties. The experience was carried out in 2016, in the western part of Romania, in Husasău de Tinca village, in Bihor, where 14 salad varieties were grown in an ecological system.
