The objective of this study was to evaluate the productivity of bags of coffee processed using different cultivars of Coffea canephora (conilon and Robusta) in an experimental area in the municipality of Humaitá, Amazonas. The research was conducted at the Mangabeiras Experimental Farm, linked to the Institute of Education and Agriculture of Amazonas (IEAA), of the Federal University of Amazonas (UFAM), Humaitá campus. The experimental unit consisted of ten hybrids ('Conilon' x 'Robusta') from Embrapa Rondônia's Coffea canephora Breeding Program and five clones that make up a cultivar adapted to tropical and low altitude conditions, called Conilon cv. BRS Ouro Preto. The design used was a randomized block design, with fifteen treatments, four replications, with each replication consisting of eight plants. The crop was established in a 3.0 x 1.0 m spacing, occupying a total area of 1,638m². The production data refers to the first years of production of the coffee crop, corresponding to the first harvest (2020/2021 harvest), the second harvest (2021/2022 harvest) and the third harvest (2022/2023 harvest). Harvesting was carried out manually, with all fruits being stripped when they reached 80% maturity (cherry). For productive evaluation, the average production in kilos per plant was calculated, and, subsequently, estimated, through calculations and correction factor, and consequently the production of bags of processed coffee per hectare. The data were subjected to analysis of variance (ANOVA), and the means were compared using the Tukey test, with a significance level of 5%. Through the analyses, it was observed that all fifteen cultivars presented satisfactory results, surpassing the average production of processed coffee per hectare in the state of Amazonas (21 sc/ha-1) and in Brazil (29 sc/ha-1). These results indicate a high productive potential of the cultivars, even in the first years of production, with the following cultivars standing out: BRS 1213 (64 sc/ha-1); BRS 3336 (61 sc/ha-1); BRS 2214 (59 sc/ha-1) and Clone 15 (58 sc/ha-1).
