Abstract
O objetivo deste trabalho foi avaliar o uso de diferentes substratos para a produção de mudas das goiabeiras 'Paluma' e 'Século XXI'. Estacas herbáceas enraizadas de ambas as cultivares foram plantadas em sacos plásticos pretos perfurados de 3L, contendo como substratos: solo puro (Latossolo), mistura de solo+areia+matéria orgânica (esterco de curral) (2:1:1), Plantmax® e fibra de coco Sococo®. A partir dos 45 dias do transplantio, foi avaliado o comprimento da parte aérea quinzenalmente e, após 180 dias, foram avaliadas: as massas seca e fresca da parte aérea; as massas seca e fresca do sistema radicial; o número de raízes por planta, e o comprimento de raízes. Concluiu-se que os melhores substratos para a produção de mudas de goiabeiras 'Paluma' e 'Século XXI' são a mistura de solo+areia+matéria orgânica (esterco de curral) (2:1:1) e o Plantmax®.
The objective of this study was to evaluate the production of 'Paluma' and 'Século XXI' guava nursery plants on four types of substrates. Herbaceous rooted cuttings from both cultivars were planted in black plastic bags of 3L containing as substrates: pure soil (Latossolo), mixture of soil + sand + organic matter (corral manure) (2:1:1), Plantmax® and coconut fiber Sococo®. After 45 days of the transplantation, the length of the aerial part was evaluated each fifteen days, and after 180 days were evaluated: the fresh and dry mass of aerial part, the fresh and dry mass of the roots, the number of roots per plant, and the root length. The results showed that the better development of rooting system and stems occurred on the mixture of soil + sand + organic matter and Plantmax® substrates.
