This area is located at the Barra do Alegre Farm, with planting on 03/27/2018 of the RB 867515 variety in a conventional soil preparation system in an area of 23.95 ha. Stalk yield of 79.94 Mg ha^-1 in the 2018/2019 harvest.
C3	An area with three sugarcane crop cycles at Fratari Farm, planted on 09/01/2015 with the RB 867515 variety in a conventional soil preparation system, with an area of 22.75 ha. Stalk yield of 83.29 Mg ha^-1 in the 2018/2019 harvest.
C7	An area with seven sugarcane crop cycles, located at Campos Farm, planted on 04/03/2013 with the RB 867515 variety in a conventional soil preparation system, with an area of 23.95 ha. Stalk yield of 79.94 Mg ha^-1 in the 2018/2019 harvest.
