The objective of this work was to evaluate the performance of “coffee from the countryside” in different cultivars of coffea canephora (conilon and robusta) using a prognostic model in the municipality of Humaitá - Am. The work was carried out at the Experimental Farm Mangabeiras, belonging to the Institute of Education and Agriculture of Amazonas - IEAA, Federal University of Amazonas - UFAM, Humaitá campus. The experimental unit is composed of ten hybrids ('Conilon' x 'Robusta') from the Coffea canephora Improvement Program of Embrapa Rondônia and five clones that make up the cultivar adapted to tropical and low-altitude conditions, Conilon cv. BRS Ouro Preto. A randomized block design was used, with fifteen treatments, four replications, each replication consisting of eight plants. The crop is arranged in 3.0 x 1.0 m spacing, with a total area of 1,638m2. Productive data refer to the first years of coffee crop production, which corresponded to the first harvest – 2020/2021 harvest and the second harvest – 2021/2022 harvest. Harvesting was carried out manually by stripping all the fruits when they reached 80% of the ripe fruits (cherry). For productive evaluation, the average production of kilograms per plant was calculated and later, based on calculations and the correction factor, the production of bags per hectare was estimated. Data were subjected to analysis of variance (ANOVA) and means compared by Tukey's test at 5% probability. The most productive cultivars were BRS 3193, BRS 2336, BRS 2299, BRS 3220 and BRS 2314 with average production of (42, 38, 35, 34, 32 and 31, respectively) bags per hectare. While the other cultivars showed intermediate results. Thus, it is concluded that all cultivars except for cultivar 3213 showed satisfactory results, reaching the average production of bags per hectare for the state of Amazonas, which suggests a high productive potential even in the first years of production.
