1. Influence of the climate on productivity and the eucalyptus drought response and a proposal for maximizing wood productivity in function of soil attributes in Brazil
Resumo Os ganhos genéticos dos programas de melhoramento do eucalipto diminuíram em comparação com as décadas anteriores, enquanto a produtividade reduziu nos últimos anos. Essa queda é atribuída principalmente às mudanças climáticas, que, segundo estudos, têm limitado a produtividade e alterado a adaptação das espécies florestais. Além disso

2. The importance of education
Abstract The present research is dedicated to analyzing the addition of sawdust biomass, which is a carbonaceous raw material that may be used in coal blends for the production of metallurgical coke, preserving the required quality, with lower cost. The quality of metallurgical coke may be determined by the efficiency of its chemical, physical and thermal fu

4. Agroforestry systems and understory harvest management: the impact on growth and productivity of dual-purpose wheat
Abstract: The objective of the study was to evaluate the growth and production efficiency of forage-grain dual-purpose wheat in two arrangements and four agroforestry systems (Intercrop-I and Intercrop-II), as well as to evaluate crop management for the wheat crops in two planting seasons (Crop Season I-2014 and Crop Season II-2015. The experiment was condu

5. Avaliação da resistência de progênies de Eucalyptus grandis para mancha foliar de Cylindrocladium e Kirramyces
RESUMO Durante o cultivo do eucalipto existem várias doenças que podem limitar sua produtividade, tal como as manchas foliares causadas por Cylindrocladium spp. e Kirramyces epicoccoides. Assim, este trabalho teve como objetivo avaliar a resistência de progênies de Eucalyptus grandis a estas doenças. O teste de progênie com 176 progênies e três teste

6. THE ECONOMIC ANALYSIS OF WOOD AND CHARCOAL PRODUCTION BY Eucalyptus REFORESTATION IN NORTHWESTERN MINAS GERAIS
RESUMO O presente estudo teve como objetivo analisar economicamente a produção de madeira e carvão vegetal de um povoamento de Eucalyptus estratificado em três classes de produtividade no noroeste de Minas Gerais. Foram utilizados dados de povoamentos de Eucalyptus não desbastados cuja área foi estratificada em alta, média e baixa produtividade, sendo

7. Geotechnology as a Planning Tool in the Determination of Forest Extraction Costs
ABSTRACT The objective of this work was to use the geotechnology study as a planning tool in determining the costs of forest extraction. The research was carried out in areas of the Forest Company that operates in the southern region of Bahia, Brazil. The work was developed in two stages, the first corresponding to the determination of production costs of th

8. Intra-and intergenotypic competition among commercial eucalyptus clones
Abstract Plantations made up of clones carry genetic uniformity that can compromise production. The use of multiclonal plantations is a possible solution. The objective of this study was to identify effects of competition on silvicultural performance of Eucalyptus spp. commercial clones. The experiment was carried out in a randomized block design with 12 euc

10. Selection of Eucalyptus grandis families across contrasting environmental conditions
Abstract The objective was to select productive and stable E. grandis families across contrasting sites in Brazil and Uruguay. Survival and growth of 130 open pollinated families were evaluated three years after planting. Survival ranged from 28 to 89% and mean annual increment from 20.5 to 48.4 m3ha- y-1. Low productivity in one site was attributed to unusu

11. Biomass Deposition and Chemical Composition of Litterfall in Clonal Eucalyptus Plantations
ABSTRACT Productivity in clonal eucalyptus plantations depends on the genetic material and on the demand and cycling of nutrients, making studies that evaluate these requirements necessary. The aim of this study was to evaluate the effect of management (with and without thinning) on the deposition, chemical composition and nutrient contribution in litter at

12. Dynamics of Eucalyptus Diameter Distribution in the State of Minas Gerais
ABSTRACT The aim of this study was to evaluate the effects of age, site, and density factors on the dynamics of eucalyptus diameter distribution. Data were obtained from a continuous forest inventory measured at different occasions, stratified according to the factors evaluated and adjusted by the three-parameter Weibull function using nonthinned clonal plo
