Resumo: | Aiming to evaluate the dose and application schedule of foliar Zn-sulfate spraying in growing and yield of Arabic coffee Mundo Novo, a field experiment was set up on Distroferric Red Latosol, at the Experimental Station of the EPAMIG in São Sebastião do Paraíso. The statistical design used was randomized blocks in s 4 x 2 factorial scheme with five replications and a 30-plant plot with six central valid plants. Zinc sulfate (ZnSO4) was sprayed under 4 concentrations 0; 0.5; 1.0 and 1.5%, two or four applications per agricultural year. Phosphorus and zinc leaf levels were evaluated for eight years and the yields. It was possible to conclude that there is a positive response to the increasing concentrations of ZnSO4 applied on the leaves in terms of yield, and to Zn levels in the leaves. Four low concentrations sprayings promoted higher yields than two high concentrations. The highest yields were achieved with 10.8 and 12.6 kg ha-1 of ZnSO4, for 2 and 4 yearly applications, respectively. It is suggested as a critical range for the Zn leaves values between 10 and 28 mg kg-1 and for P/Zn ratio, between 100 and 150. |

O delineamento experimental foi em blocos casualizados, em esquema fatorial 4 x 2, com cinco repetições e parcela de 30 plantas com seis úteis. As quantidades de sulfato de zinco (ZnSO4) foram aplicadas nas concentrações de 0; 0,5; 1,0 e 1,5%, testadas em duas ou quatro aplicações por ano agrícola. Foram avaliados por oito anos os teores foliares de P e Zn e as produções. Concluiu-se que o cafeeiro respondeu positivamente às aplicações de doses crescentes de ZnSO4 via foliar, aumentando a produção e também os teores foliares de Zn. Maior número de pulverizações de ZnSO4 em menores concentrações foi superior aos tratamentos com menor número de pulverizações mais concentradas, promovendo maiores produções. As produções máximas foram obtidas com doses de 10,8 e 12,6 kg ha-1 de ZnSO4, para duas e quatro aplicações anuais, respectivamente. Sugerem-se valores entre 10 e 28 mg kg-1 como faixa crítica foliar de Zn, e valores de 100 a 150 para relação P/Zn.Universidade Estadual de Maringá2009-03-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/662710.4025/actasciagron.v31i1.6627Acta Scientiarum.
