AVALIAÇÃO DE CULTIVARES DE BATATA-DOCE NAS CONDIÇÕES EDAFOCLIMÁTICAS DO MUNICÍPIO DE CONCÓRDIA, OESTE CATARINENSE

Abstract

Sweet potato is a standout vegetable for its simple, ease, and cheap cultivation, versatile for human and animal consumption and raw material for industries.The non-improved local cultivar contributes to the average national low productivity, with potential below from those improved and adapted to the conditions of each region. This research aimed to evaluate the performance of five commercial cultivars from Empresa Brasileira de Pesquisa Agropecuária (Brazilian Agricultural Research Corporation) (EMBRAPA, Portuguese acronym) and one local cultivar regarding to yield of root and green mass. The experiment was carried out in the Instituto Federal Catarinense (Catarinense Federal Institute) (IFC, Portugueses acronym), Concórdia municipality, Santa Catarina State, Brazil, in randomized blocks with six cultivars, five replicates, and eight useful plants per plot. The seedlings grown in greenhouses were transplanted in different places and were harvested at 150th day after transplantation. The production of green mass, aerial dry mass, total root mass, commercial root mass, average mass of commercial root, length and diameter of commercial roots, and cooking time were evaluated. The cultivar Brazlândia Branca stood out on the production of green mass and aerial part dry mass in both cycles. Every cultivar showed a higher roots yield on the second cycle. Cultivar Beauregard stood out in both cycles for production of commercial roots mass, not differing from BRS Rubissol, Roxinha, and BRS Amélia on the second cycle. Significative differences have been observed among the cultivars referring to all variables, except for the average length of commercial roots on the second cycle.
