Abstract


The study was conducted in the experimental area of Department of Agronomy, campus Cedeteg of the State University Center West, Guarapuava - PR. It aimed to evaluate the productivity and classification of tubers and the severity and incidence of scab on the potato crop in succession crops of vetch (Vicia sativa L.), oat (Avena strigosa L.), wheat (Triticum aestivum L.), radish (Raphanus sativus L.) and fallow area. It was observed that the productivity and the diameter of the tubers were not affected by treatments. The cultivation of oat as predecessor increases the severity of common scab (Streptomyces spp), and fallow and culture of vetch as predecessor caused an increase in severity of silver scab (Helminthosporium solani Dur. e Mont.).
