“…This marked variability can be explained both by the productive potential differences between cultivars, as well as due to occurrence of other abiotic stresses such as the occurrence of minimum temperatures, in the time and magnitude sufficient to cause sterility of the spikelet. This effect was observed as a consequence of the time of sowing used (Steinmetz et al, 2013). Thermal stress is captured by the model of culture derived from dates of sowing, which provide the occurrence of reproductive stages outside the ideal period.…”

“…A maior ocorrência de chuvas neste período resultou também em maior quantidade de dias nublados o que, associado ao sombreamento proporcionado pelas telas, resultou em efeito adverso na produtividade comparado ao pleno sol. Trabalhos têm mostrado o impacto das condições meteorológicas no desempenho das culturas (Caliman et al, 2005;Steinmetz et al, 2013). Wolff & Coltman (1990) também verificaram que as respostas das plantas são distintas de acordo com a época de cultivo.…”

“…Entre os locais (Figura 3C), os maiores potenciais de produtividade na Fronteira Oeste e Campanha (representadas pelos municípios de Uruguaiana e Bagé, respectivamente) são explicados pela maior disponibilidade de radiação solar nestas regiões (Steinmetz et al, 2013).…”
