Summary: AbstractSweet cassavais cultivatedthroughout Brazil, but needs to be better studied in the Cerrado region that has potential for its cultivation. The objective of this work was to evaluate the performanceof sweet cassava cultivars in Cerrado soil duringtwo growing season.The experiments were carried in 2016-2017 and 2017-2018with six cultivars, in Jataí-GO. The experimental design was factorial scheme 6 x 2,being 6cultivarsand two growing season, with three replications.The following evaluations were carried out: number of stems, stem diameter, height of the first branch, height of plants, number of roots per plant, length of roots, diameter of roots, weight of fresh roots, weight of fresh roots, weight of fresh shoots, harvest index and cooking time. The cultivar BRS 399 hadbetter root yield in the two crop years.The cultivars BRS 399, BRS 400, BRS 401 and IAC 576/70 increased the plant shoot weightfrom the first to the second growing season.The harvest index of cultivars BRS 400 and BRS 401 decreased from the first to the second growing season.It was concluded that the cultivars BRS 397, BRS 398, BRS 399 and IAC 576/70 presented the best agronomic performance in the 2016/2017 growing season, in turn, in the growing season2017/2018, the cultivars BRS 397, BRS 399 and BRS400 presented the best results. The cultivars BRS-397 and BRS-399 showed more stable agronomic behavior than the others.
