Root niche differentiation for optimal exploitation of resources was found in an arabica coffee agroforestry system in Nicaragua. Rooting behavior was compared in both unshaded (FS) and shaded (AFS) coffee combined with two previously untested tropical timber species (deciduous Tabebuia rosea Bertol. and evergreen Simarouba glauca DC.). The predominant andisol possesses a compacted soil layer (talpetate). The study was conducted in sub-optimal environmental conditions for coffee cultivation (455 m.a.s.l., annual mean 27 °C, 1300 mm rainfall/year, 6 months dry season) in Nicaragua. Twelve and five trenches 200 cm deep were dug in AFS and FS respectively. Roots per unit area were counted on two perpendicular soil faces. Volumetric water was measured continuously over 2 years by using 45 reflectometers in different soil layers. The talpetate varied greatly in depth, thickness and physical structure. Coffee fine roots were more abundant than tree roots and were concentrated in the shallower strata (0?80 cm) whilst tree roots proliferated more below 100 cm. The S. glauca root system was denser below 100 cm than T. rosea root system. There was no meaningful difference in coffee root counts in FS and under T. rosea, but coffee root counts were higher near S. glauca trees. 2012 and 2014 had mild dry seasons and whole profile soil water content was similar in FS and AFS, but in the 2013 severe dry period volumetric water and water uptake were lower in AFS than in FS. This indicates that the normal advantage of greater soil exploration in AFS was cancelled presumably due to continued water uptake by deep rooting trees whereas the FS still had available water.

Para alcançar a sustentabilidade e a competitividade da produção cafeeira é necessário investir em tecnologias inovadoras capazes de aumentar a eficiência das lavouras, reduzir custos, alavancar os processos de certificação e produzir café de qualidade. Diante deste contexto, o Instituto Capixaba de Pesquisa, Assistência Técnica e Extensão Rural (Incaper) apresenta em Brejetuba, nesta quinta-feira (04), uma nova tecnologia: a Poda Programada de Ciclo em Café Arábica (PPCA). O objetivo é oferecer ao produtor rural uma alternativa mais sustentável de manejo das lavouras de café arábica, que proporcione maior longevidade, com manutenção de seu potencial produtivo. Após sucessivas colheitas é comum observar a campo, a perda de vigor dos ramos, que se tornam pouco produtivos, paralelamente com o aumento da altura das plantas. |
