“…However, projections found in this study (as also found by [32]) showed that the start of soybean cycle may be compromised by the delay of the rainy season due to rainfall changing patterns, as also soybean cycle gets slightly longer due to atmospheric conditions. For maize, results are even more pessimistic in the sense of the inevitable yield decreases due to warmer and more variable rainfall conditions, as found by [26,37] for several regions in Brazil, which also include Mato Grosso. This is a potential threat to the recent implementation of double-cropping systems (soybean-maize), made possible by adapted genetic materials and favorable climate in Central Brazil [1].…”

“…Por isso, analisamos apenas o impacto projetado da DEF e EXC nas principais culturas agrícolas cultivadas em Itajubá. O milho é susceptível à DEF especialmente durante o pendoamento, florescimento, polinização (RAMIREZ-CABRAL et al, 2017) e, principalmente, durante o enchimento de grãos, no qual a DEF causa perdas de 90% no rendimento (DOORENBOS; KASSAM, 1979;RAMIREZ-CABRAL et al, 2017;RESENDE et al, 2019). Em Itajubá, o enchimento de grãos ocorre entre os meses de janeiro, nos plantios antecipados no decêndio 28: 05/10, a abril, nos plantios tardios no decêndio 36: 25/12 (MAPA, portaria nº55), justamente no período que ocorre aumento da DEF (Figura 3F).…”

Por outro lado, prejuízos também decorrem do aumento do EXC na fase que antecede o pendoamento (RESENDE et al, 2019), que ocorre entre os meses de novembro, nos plantios antecipados no decêndio 28: 05/10, a fevereiro, nos plantios tardios no decêndio 36: 25/12 (MAPA, portaria nº55). Justamente aqueles em que há projeção de aumento da (Figura 2D) e do EXC (Figura 3D).…”
