SUMMARY:

The productivity of sugarcane in Alagoas, as well as in the Northeast region of Brazil, despite the high level of technology used, is still low and the main reason is the irregularity of rainfall during the agricultural years, which normally has water deficiencies. One of the solutions to mitigate the effects of these deficiencies is the use of irrigation, which can increase culm productivity by more than 60%.But this technology is costly and when severe droughts occur there is no water to irrigate most of the sugarcane fields. Therefore, another alternative is the search for adapted cultivars to restrictive environments, with occurrences of water deficits (droughts) and infestations of pests and diseases that compromise the quality of the sugarcane and the quantity produced per unit of area. On the other hand, there is also a search for other sugarcane profiles, such as energy cane, to meet the demand for biomass to generate electricity and second-generation ethanol. So, with the objective of evaluating the agro-industrial yields of RB sugarcane genotypes, with different agronomic profiles (traditional sugarcane, energy cane and drought-tolerant sugarcane), in four harvest cycles, it was implemented an experiment with six sugarcane genotypes, grouped into three profiles: I - traditional sugarcane (RB92579 and RB951541); II - drought-tolerant sugarcane (RB0442 and RB0459) and; III - energy cane (RB11999 and RB13403), from November 2016 to February 2021, in an area of approximately 0.50 hectares, on the Campus of Engineering and Agricultural Sciences of the Federal University of Alagoas, Rio Largo, Alagoas. In the four harvest cycles the average agricultural productivity of the genotypes were: RB13403 (103.6 t ha^-1), RB0459 (95.2 t ha^-1), RB11999 (90.8 t ha^-1), RB0442 (88, 3 t ha^-1), RB92579 (73.5 t ha^-1) and RB951541 (72.4 t ha^-1).
