“…The growth of a forest stand depends on the genetic material, age, productive capacity, the degree of utilization of the productive potential of the site, silvicultural treatments, and the most relevant environmental factors are the availability of water for the plants throughout the years, temperature, and solar radiation (Campos & Leite, 2017;de Alcantra et al, 2018). The clones developed in Minas Gerais showed a good adaptation to the environmental conditions of the site, with high production (dos Santos et al, 2017).…”

Optimizing tree spacing in a forest plantation is one of the main management techniques to improve stand quality and productivity. Its influence on growth from an early age is an important matter for forest management. This study aims to evaluate the effect of tree spacing on early growth rate and yield over time in Eucalyptus grandis × Eucalyptus camaldulensis hybrids. The data were obtained from an experiment in Itamarandiba, Minas Gerais, Brazil. The plots were composed of five planting spacing (3.00 m × 0.50 m, 3.00 m × 1.00 m, 3.00 m × 1.50 m, 3.00 m × 2.00 m, and 3.00 m × 3.00 m) measured at the ages of 7, 12, 24, 36, 48, 61, 77, 85, and 102 months. Growth and yield were analyzed by fitting the Gompertz model and a baseline exponential model up to 36 months of age to evaluate the influence of early growth on the harvest age. A Pearson correlation matrix was also generated to find out the relationship between the mean annual increment in the respective treatments during the studied period. It was observed that a positive correlation in the average annual increase in the 3 × 2 and 3 × 3 spacings. It was verified that tree spacing influenced the yielded wood volume and the optimal harvest age. The early growth rate influences the optimal harvest, which may explain a possible loss of yield during the productive cycle of the forest stand.

“…urograndis showed greater growth, which can be attributed to the greater number and intensity of damage and weaknesses observed in E. cloeziana, due to the continuous attack of Trigona spinipes, causing branches and bifurcations and also weed interference (Table 2). According to Santos et al (2017), it is important to use eucalyptus clones that are more adapted to local edaphoclimatic conditions and that are more productive and have quality wood for multiple uses. Pulrolnik et al (2010) studied the growth of E. cloeziana and E. urograndis in the Cerrado of the Amazon region and reported higher DSH and Ht values than found in the present study.…”

Background The integrated crop-livestock-forest (ICLF) system is a sustainable production model composed by tree species intercropped with annual crops and forage species. The choice of the tree species that will compose the ICLF is characterized as a fundamental requirement in the adoption of the system. Therefore, this study aimed to analyze the initial growth and adaptation of two eucalyptus genotypes cultivated in ICLF systems in the Brazilian Cerrado. Methods The eucalyptus genotypes (E. cloeziana and E. urograndis) were intercropped with Sorghum bicolor and Urochloa brizantha in two ICLF systems in Minas Gerais State, Brazil. Qualitative data expressed by occurrences of damage and weaknesses, as well as quantitative data measured by survival rates, diameter at soil height, diameter at breast height, and total height of trees were evaluated in four periods. The data were analyzed by a correlation matrix and analysis of variance, and them qualitative and quantitative data to were analyzed in relation to the rainfall distribution during the studied period. Results The occurrence of Trigona spinipes and termite were the main biotic factors that caused damage and weaknesses to E. cloeziana and E. urograndis, respectively, directly impacting the initial growth and survival rate of eucalyptus.. The growth of E. urograndis was higher than E. cloeziana at 450, 630, 1020, and 1320 days after transplanting. On the other hand, E. cloeziana showed the highest survival rate (80.6%) while E. urograndis presented greater tolerance to the water stress. Conclusion The hibrid E. urograndis proved to be more adapted to edaphoclimatic conditions studied in the Cerrado region and can be indicated to ICLF systems implanted in regions characterized by high temperatures and irregular rainfall distribution.
