Resumo
Dentre os diversos resíduos gerados durante o processo de beneficiamento do café, destaca-se aquele proveniente da secagem dos grãos, denominado na região serrana do Espírito Santo como “moinha”. Em razão de sua potencialidade nutricional e a necessidade de dispô-lo adequadamente no meio ambiente, objetivou-se, com a realização deste trabalho, avaliar o uso de diferentes concentrações de moinha como substrato alternativo, no desenvolvimento vegetativo de mudas de café Conilon. Utilizou-se o delineamento em blocos casualizados, com 4 repetições, em esquema de parcelas subdivididas no tempo, sendo alocados nas parcelas os diferentes substratos (T1: solo + esterco bovino na proporção de 3:1; T2: 10% de moinha + solo; T3: 20% de moinha + solo; T4: 30% de moinha + solo e T5: 40% de moinha + solo) e, nas subparcelas, as diferentes idades de avaliação (60; 82; 104 e 126 dias após o plantio). As variáveis altura de muda, diâmetro de caule, diâmetro de copa, número de folhas e a matéria fresca e seca da raiz e da parte aérea foram submetidas à análise de variância, pelo teste F, e as médias, comparadas pelo teste de Dunnet (α =0,05). O uso do substrato convencional pode ser substituído pelo substrato contendo 10% de moinha, sem que haja diferença na altura de plantas, bem como nas matérias seca e fresca da parte aérea, o que demonstra seu potencial de uso como substrato alternativo para a produção mudas clonais de café Conilon.
Among the various wastes generated during the coffee in the mountainous region of the Espiríto Santo state, “moinha” stands out from graim during. Because of their nutritional potential and the need have properly in the environment, it is aimed, with this work, evaluate the use of the different concentrations of the moinha as alternative substrate for vegetative development Conilon coffee seedlings. Was used a randomized block design, with four replicates, with split plot in the time. Different substrates were allocated in the plot (T1: soil + cattle manure at a ratio of 3: 1; T2: 10% moinha + soil; T3: 20% moinha + soil, T4: 30% moinha + soil and T5: 40% moinha + soil) and, in the subplots, the different ages of evaluation (60, 82, 104 and 126 days after planting). Variables such as changes in height, stem diameter, crown diameter, number of leaves and fresh and dry matter of root and shoot were submitted to ANOVA, F test hair, and as media, compared hair test Dunnet (α = 0.05). The use of the conventional substrate can be replaced hair by the substrate containing 10% moinha without there be difference in plant height as well as in dry and fresh matter shoot, what demonstrates it potential use as for the alternative substrate for producing seedlings.
