Here, we use two gridded crop models and four climate models to assess how regional and global climate change may affect soybean productivity until 2050 under the following realistic managemen to ptions:
(i) farmers choose to plant short-cycle soybean cultivars immediately after the end of the sanitary break in order to grow two crops in the same agricultural calendar;
(ii) farmers choose to sow soybeans only under favorable climate conditions to obtain the highest productivity (one cropper agricultural calendar)
