Desenvolvimento inicial de mudas de cedro rosa (Cedrela fissilis Vell.) em diferentes concentrações de vermicomposto

Abstract

Ecological restoration practices have been widespread throughout Brazil, after national policies were created to reduce deforestation. The production of native seedlings in Brazil is still reduced due to the lack of knowledge about the needs that such crops demand and mainly due to their high diversity. The objective of the work is to analyze the development of pink cedar on different proportions of vermicompost. The experiment was conducted in a greenhouse at the Federal University of Recôncavo da Bahia, on the campus of Cruz das Almas - BA. The design was completely randomized with 6 treatments and 10 replicates. Cedrela fissilis seeds were collected on the University campus and placed to germinate. The seedlings were submitted to increasing doses in the volume / volume ratio of vermicompost + soil (0: 100, 20:80, 40:60, 60:80 and 80:20). A chemical treatment was tested for comparative effect. Significant results were found for the development of pink cedar in dosages of vermicompost, with intermediate doses statistically equal to the chemical recommendation. The best dose found was for the substrate formed by vermicompost + soil in the proportion of 40.3: 59.7.
