Agronomic performance of sugarcane crop in northwest Rio Grande do Sul state, Brazil

The aim of this study is to verify, by introducing in the northwest of the RS of19 genotypes of sugarcane, that best respond for agronomic traits to three crop years, becoming promising for cultivation by farmers in the region. The traits evaluated were: total juicebrix, juiceyield and stem mass. The experimental design was a randomized complete block with three replications. Aiming at early production the genotypes RB765418, IAC 87-3396, IAC 91-5035 and Nova Iraí are more suitable for cultivation in northwest region of Rio Grande do Sul. The genotype IAC 87-3396 after the third crop year has higher productivity juice brix and stem mass. The genotype IAC 87-3396 stands out at the end of three years as the best genotype for juice yield and stem mass.
