Resumo: Este trabalho objetiva analisar a disponibilidade hídrica da microrregião Centro-Oeste do estado do Espírito Santo e avaliar suas utilidades em um contexto de desenvolvimento sustentável. A microrregião é composta por dez municípios e está inserida na unidade de gestão de recurso hídrico (UGRH) Doce. O trabalho foi baseado no levantamento de dados secundários, em entrevistas e na participação em reuniõe...
A produção agrícola no Brasil está relacionada a condições edafoclimáticas favoráveis ao cultivo de espécies tropicais, subtropicais e temperadas. O agronegócio brasileiro representa mais de 20% do Produto Interno Bruto. Entretanto a agropecuária, por ser influenciada por condições climáticas, está relacionada diretamente a ameaça das mudanças climáticas globais. As mudanças bruscas de ambiente sensibilizam as ...
The objective of this work was to evaluate the technical efficiency of the self-propelled harvester with vibrating rods in conilon coffee plantations (Coffea canephora) and its influence on harvest costs. The tests were carried out in commercial fields, with a spacing of 3.50 x 0.50 m. In the tests, the harvest speed (1.0; 1.6 and 2.0 km h-1), the vibration frequency (700, 800 and 900 rpm) and the number of har...
This work aims to select clones of conilon coffee for the mechanized harvesting process. The study was carried out in a commercial coffee plantation in the city of São Mateus. The coffee trees were planted at a spacing of 3.5 between cultivation lines and 0.5 between plants. The characteristics were evaluated: Productivity in 60kg bags benefited per hectare (sc.ha-1); Defoliation in kg of leaf mass detached fro...

The objective of this work was to assess the spatial variability of the chemical attributes of two coffee areas, managed in conventional and organic crop systems, and to calculate the percent of variation between them. In each area, a 40-point-mesh was sampled at 0-0.10 m and 0.10-0.20 m layers, within the crown projection, for pH, SB, K, P, Ca and Mg analysis. The data were analyzed through descriptive statist...
