Resumo
O uso de novas tecnologias como forma de maximizar a produtividade da lavoura cafeeira é cada vez mais comum entre cafeicultores. Dentre as novas técnicas aplicadas pode-se citar: a prática de cultivos adensados com manejo de poda e a irrigação tanto em caráter complementar como permanente. O objetivo deste trabalho foi avaliar a capacidade de recuperação pela avaliação da produtividade de café beneficiado de cafeeiros antes e após poda por esqueletamento e decote, irrigados e não irrigados desde a implantação, em plantios adensados e não adensados. O experimento está implantado em área experimental da Universidade Federal de Lavras – MG. O plantio (cultivar Rubi MG1192) foi realizado em janeiro de 2001. A poda por esqueletamento (0,40 m do caule) e decote (1,40 m) ocorreu em setembro de 2007. Os tratamentos constaram de: parcelas irrigadas por gotejamento pelo manejo do balanço hídrico climatológico – software Irriplus (BHC) e testemunha não irrigada desde a implantação do experimento em 2001; quatro densidades de plantio de 2500 (4,0 x 1,0 m), 3333 (3,0 x 1,0 m), 5000 (2,0 x 1,0 m) e 10000 plantas ha-1 (2,0 x 0,5 m) e; duas épocas distintas, antes e após poda. O delineamento experimental foi o de blocos casualizados em esquema de parcelas subdivididas, com quatro repetições. Em densidades de 2500 (4,0 x 1,0 m) e 3333 plantas ha-1 ( 3,0 x 1,0 m) o manejo de poda foi mais eficiente para cafeeiros irrigados com aumentos de produtividade de 75 a 93%, respectivamente. Na densidade de 5000 plantas ha-1 (2,0 x 1,0 m) a irrigação favoreceu o efeito da poda porém com aumento de produtividade de 14%. Na densidade de 10000 plantas ha-1 a poda não proporcionou aumentos significativos de produtividade para cafeeiros irrigados e não irrigados.
The adoption of new technologies as a way to maximize coffee crop yield has becoming a common practice among coffee producers. Higher density plantings with controlled pruning, and complementary or permanent irrigation are among these new technologies. This study objective was to evaluate the recuperation capability by evaluating, before and after pruning, clean coffee bean yield of irrigated on non irrigated coffee plants growing under at different planting densities. The experiment was carried out at an experimental area of the Universidade Federal de Lavras - MG. Planting (cv Rubi-MG1192) was held on January 2001. Pruning (0,4m to 1,40m high) was held on September 2007. Drip irrigated parcels, receiving irrigation depths determined by the meteorological soil water balance of the Irriplus software (BHC), and non irrigated control parcels implanted at four different planting densities, 2500 (4,0 x 1,0 m), 3333 (3,0 x 1,0 m), 5000 (2,0 x 1,0 m) e 10000 plants ha-1 (2,0 x 0,5 m) were evaluated before and after pruning. An experimental design with randomized blocks with split plots and four replication s was used. For the 2500 (4,0 x 1,0 m) and 3333 plants ha-1 ( 3,0 x 1,0 m)planting densities, pruning was more effective for the irrigated parcels resulting on a yield increase of, respectively 75 and 93%. For the 5000 plants ha-1 (2,0 x 1,0 m) planting density, irrigation associated to pruning was also effective, but yield increase was only 14%. For the 10000 plants ha-1 density, it was not observed any significant increase on coffee plant yield, indicating that pruning was not effective to neither irrigated and non irrigated coffee plants .
