RESUMO

The organic agriculture offers healthy food, worries about the environmental conservation and contributes to the evolution of sustainability. Yet, it is extremely important the selection of adapted cultivars to these conditions of cultivation. The present work had as objective study the conduct of cauliflower cultivars and hybrids (Brassica oleracea var. batritys), by the system of direct and conventional planting in a conversion phase to the organic system of production. The work was conducted in two phases, in an experimental area of the Agricultural Department of UFLA, Lavras, MG. The first phase constituted in the installation of sorghum (Sorghum bicolor L. Moench), a plant used as dry material. It was verified that the sorghum presented good productivity of fresh material and dry material, and low index of new sprouting. On the second phase, the transplanting of the cauliflower cultivars was done on a mulch produced on the treatments of the first phase and on the treatments where the straw was absent. Lining in random blocks was used, with 4 repetitions in a 10x2 factorial scheme. The hybrid Silver Streak was the one that presented higher productivity and obtained better results in all tested characteristics. The hybrids HE1 and HE2, and the cultivar Snowball, did not have a satisfactory behavior at the period that the experiment was done.
