The objective of the present study was to characterize the duration of the phenological stages, the agronomic characteristics and grain yield in soybean cultivars with contrasting cycles and indeterminate growth type, submitted to different fertilization investment environments under no-tillage system in the central region of Minas Gerais. The work was conducted under field conditions, in an experimental area of Embrapa Maize and Sorghum, in Sete Lagoas, MG, in the harvest of 2015/2016. Ten soybean cultivars with different relative maturity groups (RMG) were studied, representing almost all RMG materials currently sown in Minas Gerais, in two environments with different levels of fertilizer investment. The variables were submitted to analysis of joint variance, in order to verify the existence of interaction between cultivars and investment in fertilization environments. Fertilizer investment levels influence grain yield of soybean cultivars of contrasting cycles. The higher height of the soybean plants implies higher lodging and lower grain yield. This situation is aggravated by the greater investment in fertilization. The difference between the cycles of the cultivars is in the duration of the vegetative stages, being greater in the later cultivars. |

The objective of this study was to evaluate the soil organic carbon stock and litter mass in silvopastoral systems (SSP) implemented with Urochloa decumbens and diferent Eucalyptus spatial arrangements. The SSP was implemented in 2008 with the spatial arrangements of (3×2)+20 m (434 trees ha−1), (2×2)+9 m (909 trees ha−1) and 9×2 m (556 trees ha−1) formed by the Eucalyptus cultivars GG100, I144 and VM 58. Soil samples at 0 to 20 and 0 to 40 cm depths were collected in SSP in 2011 and 2015 to determine soil organic carbon stock. The soil organic carbon stock was 38.5% higher in 2015 compared to 2011 (111 vs. 80.7 Mg ha−1), which represented an annual sink of 6.22 Mg ha−1 and indicates an increase in carbon stock over years. Litter mass was greater under the canopy than between trees, probably due to the greater drop in biomass in this location. The silvopastoral systems showed similar volumes of litter and soil organic carbon, which indicates that the evaluated arrangements have similar capacities to store carbon. |
