The exploratory analysis shown an increase in sugarcane harvest area after the year of 2000, which also increase the sugarcane production in Brazil. However, the yield does not follow this variation ( Exploratory analysis).
Therefore, modeling the yield values by municipality with year (Figure 1) shown that since the start of the database an increase in yield. The model is significative (p<0.001) and with positive slope (a= 0.369) showing the positive correlation. However, the mean values of each year had more variation. This, the mean values shown a decrease in yield after the year 2010 (Figure 1).
