Zusammenfassung: | For composted industrial wastes have high potential to use as substrate for seedling production of ornamental species, therefore that the aim of this work was to evaluate emergency and plant growth of ornamental Capsicum and Celosia in substrate based of tannery sludge compost. The experiment was carried out in trays and substrates were: tannery sludge compost, tannery sludge compost + 10% vermiculite, tannery sludge compost + 20% vermiculite, commercial substrate used as control In the tannery sludge compost there was an increase in the rate of seedling emergence only for ornamental pepper For the plant biomass, height and root length the highest values occurred in treatments where the substrate was tannery sludge compost as compared as with commercial substrate. The higher value of root biomass was obtained when the substrate was tannery sludge composted associated with 10% vermiculite. The tannery sludge compost may be a potential alternative for use as substrate in seedling production of ornamental Capsicum and celosia. Key words: industrial waste, composting, ornamental plant, seedling. Ha grande potencial de uso dos residuos industriais compostados como substrato na producao de mudas de especies ornamentais. O objetivo deste trabalho foi avaliar a emergencia e o crescimento inicial de plantulas de pimenta ornamental e celosia em substratos a base de composto de lodo de curtume. O experimento foi instalado em bandejas de isopor e os substratos utilizados foram: composto de lodo de curtume; composto de lodo de curtume + 10% de vermiculita; composto de lodo de curtume + 20% de vermiculita; substrato comercial a base de turfa, usado como controle. No composto de lodo de curtume, houve aumento na velocidade de emergencia das plantulas apenas para pimenta ornamental. Para a fitomassa, a altura das plantas e para o comprimento das raizes, os maiores valores ocorreram nos tratamentos em que o substrato foi o composto de lodo de curtume, em relacao a turfa. O maior valor de fitomassa das raizes foi obtido quando 0 substrato foi o composto de lodo de curtume associado com 10% de vermiculita. O composto de lodo de curtume e uma alternativa potencial para uso como substrato na producao de mudas de pimenta ornamental e celosia. Palavras-chave: residuo industrial, compostagem, plantas ornamentais, mudas. |
