RESUMOAplicações de gesso agrícola em lavouras cafeeiras têm sido empregadas para atuar como condicionantes e corretivos de solos. O objetivo deste trabalho foi avaliar o efeito da aplicação de diferentes doses de gesso agrícola, em diferentes formas de aplicação, na produtividade de safras de cafeeiro. O experimento foi conduzido na Fazenda Paraíso, município de Paraguaçu, MG, e o gesso aplicado quatro meses após o plantio da cultivar Catucaí. Foram aplicadas as doses de 0, 13, 26, 39 e 52 toneladas/hectare de gesso agrícola, em linha de plantio e em área total. Foram avaliados os parâmetros incremento de produtividade e produção em litros de café cereja produzido por planta, e médias foram comparadas pelo Tukey a 5% de probabilidade. Em termos de produtividade, houve diferença estatística na dosagem de 52 ton/ha, tanto na aplicação em linha quanto em área total, com um incremento de 22,9% na média das safras avaliadas. A quantidade de litros de café cereja por planta teve um acréscimo de 33,9%, na dose de 52 ton/ha, nos dois tipos de aplicação. Conclui-se que aplicações de doses mais elevadas de gesso agrícola incrementa a produção, podendo ser uma alternativa para os produtores como prática de manejo de lavouras cafeeiras.
ABSTRACT
Applications of phosphogypsum in coffee plantations have been employed to act as constraints and soil amendments. The objective of this study was to evaluate the effect of different doses of phosphogypsum in different forms of application, productivity of coffee crops. The experiment was conducted at Paradise Farm, municipality of Paraguaçu, MG, and the plaster applied four months after planting cultivar Catucaí. They were applied doses of 0, 13, 26, 39 and 52 tons / ha of phosphogypsum in the rows and in total area. We evaluated the parameters increase productivity and production in liters of coffee cherries produced per plant, and means were compared by Tukey at 5% probability. In terms of productivity, there was no statistical difference in the dosage of 52 ton / ha, both in the online application and in total area, with an increase of 22.9% than the single vintages. The number of liters of coffee cherry per plant had an increase of 33.9% at a dose of 52 ton / ha, in both types of application. It was concluded that application of higher doses of phosphogypsum increases production and can be an alternative for producers as practical management of coffee crops.
