Um dos principais problemas enfrentados no cultivo de café conilon (Coffea canephora Pierre ex A. Froehner) é a falta de mão de obra no campo. Parte significativa das lavouras no Estado do Espírito Santo está em áreas com topografia declivosa, o que dificulta o uso de máquinas agrícolas. A mecanização agrícola tem sido apontada como uma alternativa viável para garantir a viabilidade técnica e econômica do cultivo de café conilon em áreas aptas. Alguns estudos apontam o potencial de uso de novas tecnologias (agricultura de precisão) na melhoria do manejo da lavoura. O objetivo deste trabalho é apresentar novas tendências para o manejo mecanizado do cafeeiro conilon como alternativa para a melhoria de coeficientes técnicos e econômicos, tornando a atividade mais sustentável e competitiva.
One of the main problems facing the cultivation of conilon coffee (Coffea canephora Pierre ex A. Froehner) is local manpower shortage. A significant part of coffee plantations in the State of Espírito Santo, Brazil, is located in steep areas, where agricultural machines are difficult to be used. Agricultural mechanization has been pointed out as a viable alternative that can ensure the technical and economic viability of conilon coffee cultivation. Some studies reveal that the potential of the use of new technologies (precision agriculture) can improve coffee crop management. The objective of this article is to present new trends for mechanized management of conilon coffee as an alternative to the improvement of technical and economic coefficients, making the activity more sustainable and competitive.

The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR). Leaf samples were collected from two populations, located in the National Forest of Pacotuba and the Private Natural Heritage Reserve of Cafundó. Eight ISSR primers were used, which resulted in 97 bands, with 68.04% of polymorphism. Based on the joint data, the values of 0.33 for the Nei index (H*) and 0.50 for the Shannon index (I*) indicated moderate to high genetic diversity, being influenced by the presence of genetically dissimilar individuals in the National Forest of Pacotuba. Most of the genetic divergence was intrapopulational (85.96%), with moderate differentiation between populations (ΦST = 0.1404). The estimated historical gene flow between the fragments was low (Nm = 3.21) when compared with results from other tree species, and the genetic structuring analysis separated the populations into two groups, corresponding to the two populations evaluated. The results indicate a small genetic share among populations, however, populations are becoming structured. The satisfactory levels of genetic diversity benefit the use of the trees as matrixes for programs of restoration and recovery of degraded areas, connectivity of landscapes, and sustainable use of forest resources.
