“…It starts with soybean at the beginning of the agricultural season (September-October), which is also the beginning of the rains. Maize, also called as "off-season," has its sowing directly dependent on soybean harvest and mandatorily experiences the decrease and end of the rainy season (starting in March) during its development, also being subject to a more intense interannual yield variability due to water stress [5,18].…”

This study assessed potential impacts of climate on the dynamics of soybean-maize systems, a widespread cropping practice in Central Brazil, in regions of Mato Grosso state. Baseline (historical) and future climate scenarios in the mid and end of the twenty-first century were locally defined. Climate projections were input in a crop model, which was used to analyze their impact on first season's crop (soybean), and more emphasis was given on the second season's crop, maize development. In the climate projections, we observed a generalized increase in temperature for all scenarios, with variability of rainfall amount and pattern. Soybean growth showed a general enlargement of cycle length (average of up to 16%) and increase of yields (average of up to 34%) in future conditions. Soybean sowing dates and future climate contributed to the shortening of recommended maize sowing window and yield decreases. At most extreme scenarios of future climate, only soybean sown at the earliest dates would enable the latest maize sowing dates, bringing the greatest losses to the latter crop. Estimated maize yields showed relative average variations from baseline of − 22.5% and − 32.5% in RCP 4.5 in the mid and end of the century, while variations were of − 34% and − 55% in RCP 8.5 in the mid and end of the century, respectively. Timing of soybean sowing dates in a future climate will become more important in influencing the dynamics of subsequent maize's sowing dates and yields under a more extreme and unfavorable climate for its development.

“…Thus, these studies usually consider only one crop, instead of the double summer crop system, in which, different sowing date possibilities of each crop may greatly affect the economic result (Melo et al, 2012;Volsi et al, 2020). Other studies evaluated the technical performance of the different sowing dates for these crops (Arakaki & Minuzzi, 2016;Garcia et al, 2018), but do not quantify the economic result that this arrangement can result. Few studies address both themes in the same study, such as Battisti et al (2020), which analyzed the best combination of production and profitability considering different sowing periods of soybean and corn crops in the double summer crop succession.…”

The success of soybean-maize double summer crop is very dependent on the sowing date and relative maturity group of cultivars. This study aimed to evaluate the economic feasibility of the adoption of soybean-maize double cropping under different sowing periods and soybean maturity groups. The production data used were obtained from two summer growing seasons (2016/17 and 2017/18) in an experiment carried out at Dois Vizinhos-PR, Brazil. The economic feasibility of each treatment was evaluated through the indicators of gross revenue, gross margin, operating profit, and profitability index. Soybean-maize succession is viable and presents positive profitability. Soybean establishment on October 15th makes it economically unfeasible to sow maize (outside the zoning) as a 2nd summer crop. Soybean maturity groups from 5.1 to 5.3, when sown on October 1st allow profitability and better financial balance, being this combination the most suitable for a double summer crop. Soybean genotypes with maturity group 6.0 are an option for sowing in the middle of September, being the most lucrative and efficient arrangement, providing maize sowing in the middle of February, within the agroclimatic zoning of the region.

“…As quedas na produtividade do milho ocorrem por influência das condições climáticas, potencial genético de híbridos da cultura, manejo nutricional e do manejo ineficiente de pragas e doenças (GARCIA et al, 2018). Dentre esses fatores, a influência do clima na produtividade deste cultivo é a que se tem o menor poder de controle (SCHAUBERGER et al, 2017).…”

A previsão sazonal da produtividade dos cultivos pode colaborar para a mitigação de efeitos adversos da variabilidade climática. Portanto, objetivou-se calibrar um modelo geral de previsão de produtividade de milho safrinha para o estado do Mato Grosso do sul usando elementos climáticos. Foi utilizado séries históricas de dados climáticos como radiação solar global, temperaturas média, máxima e mínima do ar (°C), umidade relativa , velocidade do vento e precipitação pluvial durante o período de 1983-2018, e dados fitotécnicos de áreas produtivas de milho em Mato Grosso do Sul para estimar modelos e gerar mapas de produtividade no estado. A produtividade média das localidades da região norte foi maior em relação as localidades do sul do estado. O modelo desenvolvido para estimar a produtividade do milho safrinha em função das variáveis climáticas foi significativo (p < 0,05), com alta precisão (R2 aj) e acurácia (MAPE). O modelo calibrado apresentou relação significativa entre a produtividade do milho safrinha e a temperatura do ar no período de abril e maio, portanto, essa variável meteorológica pode ser utilizada como indicador de riscos climáticos em sistemas de produção de milho no estado do Mato Grosso do Sul.
