Formulação de substratos alternativos na formação inicial de mudas de ingazeiro

The objective of this study was to evaluate the development of seedlings of ingazeiro (Inga edulis Mart.) on alternatives substrates. The work was carried out in experimental design of randomized block with four replications and the treatments consisted of the substrates: Oxisol; Oxisol + cattle manure (20%), Oxisol + cattle manure (40%), Oxisol + sawdust (20%) and Oxisol + sawdust (40%). The diameter and height of the seedlings were measured at 106, 122, 137 and 153 days after sowing, and together with the last measurement were determined the number of leaves, root growth, fresh biomass of shoot and root, dry weight of shoot and root, total dry matter and also certain morphological indices. The treatment consists in mixing Oxisol + cattle manure (20%) showed the highest values for the morphological index resulting from the relationship between the dry weight shoot/dry weight of roots and the Dickson quality index.Objetivou-se com o presente estudo avaliar o crescimento inicial de mudas de ingazeiro (Inga edulis Mart.) em substratos alternativos. O estudo foi realizado em delineamento experimental de blocos ao acaso, com quatro repetições, sendo os tratamentos constituídos pelos substratos: Latossolo Vermelho; Latossolo Vermelho + Esterco Bovino (20%); Latossolo Vermelho + Esterco Bovino (40%); Latossolo Vermelho + Pó de Serra (20%) e Latossolo Vermelho + Pó de Serra (40%). Foram avaliados aos 106, 122, 137 e 153 dias após a semeadura o diâmetro e altura das mudas e na última aferição o número de folhas, crescimento radicular, fitomassa fresca da parte aérea e radicular, fitomassa seca da parte aérea e radicular, fitomassa seca total e determinados os índices morfológicos. O tratamento composto pela mistura do Latossolo Vermelho + Esterco Bovino (20%) promoveu os maiores valores para os índices morfológico resultante da relação entre a massa seca parte aérea/massa seca de raízes e para o índice de qualidade de Dickson
