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.

Postharvest quality of sweet maize varies depending on the type of seed, soil, quality of fertilizer, climatic conditions, and stage of maturation. This study aimed to evaluate the post-harvest quality and shelf life of green ears of maize grown on three soil covers in organic no-till sytem. The study was conducted in the municipality of Domingos Martins, ES (20° 22?16.91" S and 41° 03' 41.83" W). The experiment was arranged in a randomized block design with six replications and five treatments, consisting of three cover crops in organic no-till system: black-oat straw, white lupin, oat/lupin intercrop and two systems, organic and conventional, without straw. Maize double hybrid AG-1051 was sown in a spacing of 1.00 x 0.20 m. The variables evaluated included relative percentage of grain, straw and cob, pH, titratable acidity, soluble solids, grain moisture and shelf life. The use of different straws in the organic no-till system does not influence the postharvest quality of green ears. Ears packed in polystyrene trays with plastic film are suitable for marketing until the fifth day of storage at room temperature.
qualidade pós-colheita do milho-verde varia de acordo com o tipo de semente, de solo, da qualidade do fertilizante utilizado, das condições climáticas e do estágio de maturação. Objetivou-se avaliar a qualidade pós-colheita e o tempo de prateleira de espigas de milho-verde cultivado sobre três coberturas de solo no sistema plantio direto orgânico. O trabalho foi desenvolvido no município de Domingos Martins-ES (20° 22' 16.91"S e 41° 03' 41.83"O), sendo disposto em delineamento de blocos casualizados, com seis repetições e cinco tratamentos, constituídos por três coberturas de solo no sistema plantio direto orgânico, palha de aveia-preta, tremoço-branco e consórcio aveia/tremoço e dois sistemas sem palhada, sendo um orgânico e um convencional. Foi utilizado o híbrido duplo de milho AG-1051 no espaçamento de 1,00 x 0,20 m. Foram realizadas avaliações de percentual relativo de grãos, palha e sabugo, pH, acidez titulável total, sólidos solúveis totais, umidade dos grãos e tempo de prateleira. O uso de diferentes palhadas no sistema plantio direto orgânico não influencia a qualidade pós-colheita do milho-verde. As espigas embaladas em bandeja de poliestireno expandido com filme de PVC apresentam-se aptas a comercialização até o quinto dia de
armazenamento em temperatura ambiente. MenosPostharvest quality of sweet maize varies depending on the type of seed, soil, quality of fertilizer, climatic conditions, and stage of maturation.
