Resumo: | The objective of this work was to evaluate the effects of irrigation on leaf contents of P and Zn, on the yield, and on the growth of coffee plants (Coffea arabica) under traditional and high density planting. A randomized complete block design was used in split-plot arrangement, with four replicates. Plots consisted of planting density (3,333 and 10,000 plants ha-1), and subplots consisted of water depths applied according to four irrigation managements: beginning of irrigation whenever water tension at 0.25 m soil depth reached values near 20 or 60 kPa; fixed irrigation turn (three times a week), according to climatic water balance; and a control without irrigation. In 2009, 2010, and 2011, the following evaluations were done for: leaf concentrations of P and Zn; yield of processed coffee (bags ha-1); and lateral canopy area. Larger water irrigation depths favor root absorption of P and the vegetative growth of plants, on both traditional and high density planting systems, as well as productivity increase in the traditional system. Phosphorus increased availability for plants by greater irrigation depths decreases Zn concentration in the leaves. |

O objetivo deste trabalho foi avaliar os efeitos da irrigação sobre as concentrações foliares de P e Zn e sobre a produtividade e o crescimento do cafeeiro (Coffea arabica), cultivado em plantio tradicional e adensado. Utilizou-se o delineamento experimental de blocos ao acaso, em arranjo de parcelas subdivididas, com quatro repetições. As parcelas corresponderam às densidades de plantio (3.333 e 10.000 plantas ha-1), e as subparcelas corresponderam às lâminas d’água, aplicadas por quatro manejos de irrigação: início da irrigação, quando a tensão d'água no solo à profundidade de 0,25 m atingia valores próximos a 20 ou 60 kPa; turno fixo de irrigação (três vezes por semana), de acordo com o balanço hídrico climatológico; e testemunha sem irrigação. Em 2009, 2010 e 2011, foram feitas as seguintes avaliações: teores foliares de P e Zn; produtividade de café beneficiado (sacas ha-1); e área lateral do dossel. Lâminas de irrigação maiores favorecem a absorção radicular de P e o crescimento vegetativo das plantas no sistema tradicional e no adensado, bem como o aumento da produtividade no sistema tradicional. O aumento da disponibilidade de P para as plantas, pelo aumento da irrigação, diminui a concentração de Zn nas folhas.
