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.

O Brasil é o maior produtor e exportador mundial de café e o Estado do Espírito Santo, o maior produtor nacional de café conilon (Coffea canephora). A variedade clonal ?Incaper Vitória 8142?, desenvolvida para as condições encontradas no Estado, é composta por 13 genótipos com características de interesse. Objetivou-se com esse trabalho avaliar o crescimento e desenvolvimento inicial de mudas dos genótipos que compõem a variedade de café de Conilon ?Incaper Vitória 8142 ?, uma vez que tais informações podem auxiliar na implantação de lavouras com esta variedade. As mudas foram produzidas na Fazenda Experimental do Incaper, no município de Marilândia ? ES e as avaliações realizadas no CEUNES-UFES em São Mateus - ES. Foram avaliados genótipos da variedade, em delineamento inteiramente casualizado com nove repetições. Efetuou-se a quantificação da produção de matéria seca, crescimento, desenvolvimento radicular, índice de qualidade de Dickson e conteúdo de nutrientes em diferentes partes das mudas. Os genótipos V8 e V10 apresentaram desenvolvimento superior aos demais genótipos. Nas condições avaliadas, os genótipos V2, V3, V4, V8, V9, V10, V11 e V12 apresentaram as melhores qualidades de mudas determinada por meio do índice de qualidade de Dickson. Nitrogênio e Ferro foram os nutrientes encontrados em maior concentração, independente do genótipo.

The clonal variety ?Vitória Incaper 8142?, developed for this state environmental condition is composed of 13 genotypes with characteristics of interest. The aim of this study was to evaluate the growth and the development of conilon coffee seedlings, variety ?Vitória Incaper 8142.? The seedlings were grown at the Incaper Experimental Farm in the Marilândia City, and evaluations done at CEUNES-UFES in São Mateus in Espírito Santo State. The genotypes were evaluated by a randomized experimental statistical mode applying nine replicates. It was conducted to quantify the dry mass production, growth, root development, Dickson quality index, and nutrient content in different parts of the seedlings. The V8 and V10 genotype had higher development compared with other genotypes. Under the conditions evaluated, improved quality of seedlings of the genotypes was V2, V3, V4, V8, V9, V10, V11, and V12, which was determined by the Dickson quality index. Nitrogen and iron were the macro and micronutrients found in higher concentration, regardless of genotype.
