: Cherry tomato cultivation in protected environments ensures production in the off-season, reaching yields up to 100 t ha-1 with 150 days of cultivation. Fertilization with organic composts can influence the production components of cherry tomato. From this perspective, this study aimed to evaluate different doses and organic composts, based on their nitrogen contents, on the production components of cherry tomato. The experiment was conducted in the municipality of Boa Vista - RR, at the Agrotechnical School (EAgro) of the Federal University of Roraima (UFRR), Campus Murupu. Cherry tomato cultivation was performed in a protected environment (greenhouse). The experimental design was in randomized blocks with a 4 x 5 factorial arrangement referring to four types of compost (pigeon pea and rice husk; pigeon pea and sawdust; poultry manure and rice husk; and poultry manure and sawdust) and five doses (50, 125, 200, 275, and 350 kg ha-1) calculated based on the nitrogen content of the inputs, with four replications. The experiment evaluated the number of fruits per plant, the mean fruit mass, the mean fruit mass per plant and treatment, and the mean yield per hectare. There was no significant difference at 5% probability for the doses, composts, and the interaction between doses and composts for all studied variables. The mean yield was 14.31 t ha-1. The type of compost did not influence the production components of cherry tomato. Cherry tomato yield was not increased by the organic composts in the protected environment.
