UTILIZAÇÃO DE TORTA DE FILTRO COMO SUBSTRATO PARA A PRODUÇÃO DE MUDAS DE HORTALIÇAS

Abstract

The potential use of filter cake (a sugar cane industrial waste) as substrate for horticultural seedling production was tested. Seeds of cucumber, tomato and cabbage were sowed in polystyrene trays with three kinds of substrate: Plantmax, Bioterra and filter cake added of nutrients. At 22 days after sowing physiological characters related to development were evaluated: total root number, total root size and dry weights of aerial part and root. The filter cake substrate had the best results when compared to the other commercial ones. Therefore, the use as substrate of filter cake for horticulture seedling production is characterized as a viable alternative.
