Evaluation of hybrids of cabbage, cauliflower and broccolis under organic cultivation in two seasons on coastal areas of Santa Catarina

The aim of this study was to evaluate the productivity and disease intensity on cabbage, cauliflower and broccolis in organic cultivation in Spring/2003 and Autum/2004. Variables related to productivity were compared by Duncan test and those related to disease intensities by Kruskall Wallis test. Differences in productivity were verified only for cabbage in the Spring/2003. Broccolis and cauliflower did not differ in
productivity and head weight. Broccolis ‘AF-817’ and cauliflower ‘Sharon F1’ presented lower intensities of black spot, but not of black rot. In Autumn/2004 no differences were observed in productivity, however black rot
intensities were different for hybrids of broccolis
