Substratos para produção de mudas de Veitchia merrilli

Abstract

The objective of the work was to evaluate different substrates for seedling production of Veitchia merrillii. The experiment was conducted in the Campus of the Federal University of the Bahia Recôncavo (UFRB), in a completely randomized design composed of six treatments: T1-50% soil + 50% bovine manure (1:1 in volume); T2- 100% coconut fiber; T3-100% alone; T4-Substrate commercial; T5-100% sand and T6- 50% soil + 50% organic compost (1:1 by volume) with 20 replicates each, totaling 120 plants. The evaluated variables were: shoot height, stem diameter, leaf number, shoot fresh matter, fresh root matter, shoot dry matter, root dry matter, total dry matter and Dickson quality index. Data were submitted to analysis of variance and, afterwards, the means were compared by the Tukey test at the 5% probability level. The substrates 100% soil, 50% soil + 50% bovine manure and commercial substrate, provided better results for the production of Veitchia merrilli seedlings.
