Resumo
O presente trabalho objetiva avaliar o efeito do composto de lixo urbano orgânico (CLO) em diversas concentrações de solo (S) e o substrato padrão (SP) para formação de mudas de cafeeiro. Foi empregado delineamento inteiramente ao acaso, com 6 tratamentos e 4 repetições, além de 2 tratamentos adicionais, definindo os tratamentos: T1 = 100% (S); T2 = 90% (S) e 10% (CLO); T3 = 80% (S) e 20% (CLO); T4 = 70% (S) e 30% (CLO); T5 = 60% (S) e 40% (CLO) e T6 = 50% (S) e 50% (CLO). No tratamento adicional foram formados o T7 = 100% (SP) + P e K e T8 = 100% (SP) - P e K. Foi avaliado o peso fresco e seco de raiz e parte aérea, além da análise química dos substratos utilizados. Verificou-se maior desenvolvimento do sistema radicular e da parte aérea do cafeeiro até a dose de 20% de CLO e maiores níveis de P, K, Ca, Mg, e pH com a maior concentração do composto de lixo orgânico no substrato.
This paper aims to evaluate the effect of organic urban waste compost (CLO) in different concentrations of soil (S) and the standard substrate (SP) for training of coffee seedlings. It employed a completely randomized design with 6 treatments and 4 replicates, plus two additional treatments, defining the treatments: T1 = 100% (S), T2 = 90% (S) and 10% (CLO), T3 = 80% (S) and 20% (CLO), T4 = 70% (S) and 30% (CLO), T5 = 60% (S) and 40% (CLO) and T6 = 50% (S) and 50% (CLO ). No additional treatment were formed T7 = 100% (SP) + P and K and T8 = 100% (SP) - P and K. We evaluated the fresh and dry weight of roots and shoots, as well as chemical analysis of substrates. There was greater development of root and shoot of coffee up to the rate of 20% and higher CLO levels P, K, Ca and Mg, and pH with the highest concentration of organic waste compound in the substrate.
