Zusammenfassung: | The method of producing organic mini-cabbages from regrowth of mother-plant was initiated at the Unidade de Referencia em Agroecologia of the Incaper in 2013, possibly acting as an efficient alternative for the obtainment of cabbages with a more adequate average weight for the desires of the modern consumer. The aim of this study was to define sprout density in the mother plant, which allows better productivity and commercial standards for organic mini-cabbages. The experiment was developed during the period from September to November 2015, using the F Shinsei hybrid, in a design with randomized blocks, with five replications. Sprout density was determined following thinning, constituting the following treatments: two, three, four, five and six sprouts per plant. Best management of sprouts was the technique with four sprouts per plant, since it allowed greater productivity (52,997 kg [ha.sup.-1]) and a greater number of commercial heads, together with a commercial standard of heads with average weight (414g) and median diameter (8.8cm) adequate for the standards demanded by the consumer. Key words: Brassica oleracea, var. capitata, organic cultivation, mini -vegetables, plant density. A tecnica de producao de mini-repolhos organicos por rebrota da planta-mae foi iniciada na Unidade de Referencia em Agroecologia do Incaper, no ano de 2013, podendo ser uma alternativa eficiente para obtencao de repolhos com peso medio mais apropriado ao desejo do consumidor moderno. O objetivo deste trabalho foi definir a densidade de brotos da planta -mae, que permita melhor produtividade e padrao comercial de mini-repolhos organicos. O experimento foi desenvolvido no periodo de setembro a novembro de 2015, utilizando-se o hibrido F Shinsei, no delineamento de blocos casualizados, com cinco repeticoes. As densidades de brotos foram estabelecidas apos desbastes, constituindo os seguintes tratamentos: dois, tres. quatro, cinco e seis brotos por planta. O melhor manejo de rebrotas foi a conducao com quatro brotos por planta, pois permitiu maior produtividade (52.997kg [ha.sup.-1]) e maior numero de cabecas comerciais, aliados a um padrao comercial de cabecas com peso medio (414g) e diametro medio (8,8cm) adequados aos padroes exigidos pelo consumidor. Palavras-chave: Brassica oleracea, var. capitata, cultivo organico, mini -hortalicas, densidade de plantas. |
