Abstract

The aim of this study was to evaluate the feasibility of using some organic solutions as a plant nutrient source for tomato (Lycopersicum esculentum Mill) grown under greenhouse conditions, and the yield and quality of the fruits. Four nutrient sources were compared (Steiner nutrient solution, compost tea, vermicompost tea and vermicompost leachate). The evaluated variables were: A) yield, b) fruit quality, c) foliar nitrogen and sap petiole nitrogen, and d) chlorophyll relative content. The results showed significant differences in all variables. O objetivo do presente estudo foi avaliar a factibilidade do uso de algumas soluções orgânicas como fonte de nutrientes para tomate (Lycopersicum esculentum Mill) produzido em estufa, e o rendimento e qualidade dos frutos. Compararam-se quatro tratamentos: Solução nutritiva inorgânica (Steiner), chá de compostagem, chá de vermicompostagem e lixiviado de vermicomposto. As variáveis avaliadas foram: A) rendimento, b) qualidade da fruta (diâmetro polar, equatoriais e sólidos solúveis), c) conteúdo de nitrogênio foliar e no extrato celular de pecíolos, e d) conteúdo relativo de clorofila. Os resultados mostraram diferenças significativas em todas as variáveis avaliadas. Com a fertilização inor-The highest leaf N total contents and N-NO3- in sap petioles, chlorophyll content and increased performance, was obtained with inorganic fertilizer. However, there were lower values of soluble solids compared to those obtained with organic fertilization treatments. Within the organic fertilization treatments, vermicompost tea stood out with better performance. The results suggest that vermicompost tea can be an environmentally friendly alternative compared to conventional use of nutrient solutions in greenhouse production.
