Summary
O trabalho foi desenvolvido em duas etapas: a produção de mudas de couve-chinesa em bandejas e posterior transplante para o campo, objetivando avaliar o desempenho de diferentes substratos sobre o desenvolvimento da cultura. Para isso determinou-se, tanto na fase de formação das mudas, quanto nas plantas adultas, o comprimento da parte aérea, número de folhas, comprimento da raiz, massa seca da parte aérea, massa seca da raiz e diâmetro do coleto. A etapa de produção de mudas foi conduzida em ambiente protegido, com os seguintes tratamentos: T0 substrato comercial Plantmax® (HA); T1: 100% composto; T2: 95% composto + 2,5% areia + 2,5% pó de rocha; T3: 90% composto + 3% areia + 7% de pó de rocha e T4: 85% composto + 6% areia + 9% pó de rocha. Na produção de mudas, os substratos orgânicos, formulados com 100% e 85% composto, apresentaram melhores resultados, aos 15 e 28 DAS, respectivamente. Os resultados de campo demonstraram que adição de pó de rocha é um fator determinante no desempenho das mudas, sendo os melhores resultados obtidos nas parcelas cultivadas com mudas obtidas nos substratos formulados com 7 e 9% de pó de basalto.
Summary translation
The research was carried out in two stages: the production of seedlings of chinese cabbage in trays with subsequent transplantation for the field, aiming to evaluate the performance of different substrates on the culture development. For this reason it was determined, both at the stage of formation of the seedlings, as in adult plants the length of the aerial part, number of leaves, root length, dry mass of the aerial part, root dry mass and diameter of the root collar. The experiment was conducted in a protected environment with the following treatments: T0 Plantmax substrate® (HA); T1: 100% compound; T2: 95% compost + 2.5% sand + 2.5% rock powder; T3: 90% compost + 3% sand + 7% powdered rock and T4: 85% compost + 6% sand + 9% rock powder. In the production of seedlings, the organic substrates formulated with 100% and 85% compound, had better results, the 15 and 28, respectively. The results of field have shown that the addition of rock powder is a determinant factor in the performance of seedlings, with the best results in the plots cultivated with seedlings obtained in the substrates formulated with 7 and 9% of basalt powder.
