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.

A ferrugem do cafeeiro é causada pelo fungo Hemileia vastatrix Berk. & Br. Essa doença é considerada a mais importante para a cultura do café. Algumas populações de café conilon são altamente suscetíveis, outras totalmente resistentes, e outras, ainda, apresentam reação heterogênea à doença. Esse trabalho objetivou estudar a severidade da ferrugem do cafeeiro e a produtividade de clones de café conilon de ciclo de maturação tardio ao longo de duas safras. Foram avaliados 10 clones ao longo das safras de 2008 e 2009, em delineamento experimental em blocos casualizados, com esquema de parcelas subdivididas no tempo e quatro repetições. A análise de variância mostrou que os clones avaliados nesse estudo, ao longo de duas safras, apresentam diferentes médias para produtividade e severidade da ferrugem, ocorrendo interação entre o efeito dos clones e das safras. Na maioria dos clones, a ferrugem não atingiu os níveis mais altos de severidade, com exceção do clone NT/03 em 2009, quando a doença causou desfolha. Os clones avaliados apresentam alta produtividade média, e o ano de 2009 foi marcado por um aumento de produtividade em todos os clones.
The coffee leaf rust is caused by Hemileia vastatrix Berk & Br. The disease is considered the most important to the culture of coffee. Some populations of conilon coffee are highly susceptible, others completely
resistant, and yet others have heterogeneous reaction to the disease. This study investigated the severity of coffee leaf rust and productivity of clones of conilon coffee of late maturation cycle over two seasons. 10 clones were evaluated along the harvests of 2008 and 2009 in randomized block design with split plot in time and four replications. The variance analysis showed that the clones in this study over two seasons, have different averages for yield and severity of the disease, occurring interaction between the effect of clones and years. In most clones, the leaf rust has not reached the highest levels of severity, with the exception of clone NT/03 in 2009, when the disease caused defoliation. The clones have high average of productivity, and the year 2009 was marked by an increase in productivity in all clones.
