Características de mudas de <I>Schizolobium parahyba</I> (Velloso) Blake, submetidas a diferentes composições de substrato-fase de viveiro

Abstract

This experiment was conducted in Horto Botânico of UFSC in march, 1982 to verify the effect of destinct substrate compositions on seedling characteristics of Schizolobium parahyba (Velloso) Blake. Complete randomized block design was used with different treatments as follows; mixture of clay soil with sandy soil (control); clay soil + sandy soil + corrected fertilization; clay soil + sandy soil + cattle manure; clay soil + sandy soil + sugar cane filter press cake and clay soil + sandy soil + chiken manure in identical volume proportion. The dry matter of shoot and height of seedling was highest in treatments of mixture soil and sugar cane filter press cake or mixture soil and cattle manure. These treatments were enable to obtain better characteristics of seedling for transplanting in 70 days after emergence. The difference between destincts treatments for the stalk diameters and root dry matter was small and not significant for the most comparisions. In general, the seedlings produced in the mixtures with sugar cane filter press, cake or with cattle. manure showed better quality than the mixture with soil corrected, chicken manure and control.
