Producing food in a sustainable manner, exploiting the genetic potential of crops and optimizing cultivation time to ensure increased production are the biggest challenges for agriculture. The cultivation of super-early common bean lineages with high productive capacity leads to minor water consumption in crops under irrigation and vacate the area in less time. The objective of this work was to evaluate the yield components of super-early cycle common bean cultivars, under irrigated system in function of sources of nitrogen (N) as well as to assess different application stages. The experiment was conducted in randomized block design in a factorial scheme 4x3 + 1, corresponding of four sources of N in coverage (urea, urea + ammonium sulfate, urea + ammonium sulfate + elemental sulfur and urea + elemental sulfur), three application stages (V3, V4 and R5) and a control treatment. The N incorporation did not influence on the grain yield of the super-early cycle common bean regardless of the source and season, whereas significant results were merely found when compared to the control. The number of pods was affected when the application was carried out at the R5 stage, with a significant reduction in this yield component. The relative chlorophyll index was lower when nitrogen coverage was performed at the R5 stage. |

Leaf blight caused by the fungi of the genus Calonectria represents a high economic risk for forestry companies due to the high potential of economic damage to commercial eucalyptus plantations. An outbreak of leaf blight was observed in Eucalyptus benthamii progeny in three sites in Southern Brazil. This study aimed to: (i) identify the causal agents of the disease; (ii) quantify the incidence and severity of leaf blight (CLB), and (iii) evaluate the selection for CLB resistance potential of E. benthamii. The incidence of the disease was 100% and severity progressed over time, causingmore than 50%of canopy defoliation inmost trees. The fungal species associated with this study were C. metrosideri and C. spathulata, both found to be pathogenic; C. spathulata was the most aggressive. Infection of E. benthamii by these fungi was associated with temperatures around 18 °C and relative humidity of approximately 74%. There is sufficient genetic variability for the selection of resistant E. benthamii progenies to CLB, based on low severity degrees. |
