Excedente hídrico em diferentes solos e épocas de semeadura do girassol no Rio Grande do Sul

Abstract: O objetivo deste trabalho foi identificar datas de semeadura com menor ocorrência média de dias com excedente hídrico para a cultura do girassol, e determinar a persistência de dias consecutivos com excedente hídrico ao se considerar a capacidade de armazenamento de água disponível de diferentes solos da região central do Rio Grande do Sul. O desenvolvimento da cultura e o aprofundamento do sistema radicular foram simulados de acordo com a soma térmica para 14 datas de semeadura, de agosto até meados de fevere… Show more

“…Soil Conservation Service methodology as an estimate of soil water infiltration underestimated the number of days with EXC. However, Lucas et al (2015) deployed a similar strategy to BORT2017, with satisfactory performance for sunflower cultivation in different types of highland soils, where the use of PE is more appropriate. Gubiani et al (2018) in the 0-100 mm layer; (-) days without occurrence of water excess.…”
