SUMMARY:

Careful planning and the selection of adapted melon cultivars are essential to maximize yield and fruit quality during a specific planting period, where management practices must be adjusted according to the climatic conditions and the specific needs of the selected cultivars.

This study aimed to analyze the agronomic behavior of different melon cultivars, planted in two distinct cultivation periods, under the climatic conditions of the Roraima savanna. For this, a randomized block design was used, in a subdivided factorial scheme, with four repetitions. The main plots were composed of five melon cultivars (Crucial, Caribbean Diamond, Gladial, Gold Mine, and Natal), while the subplots were constituted by the two cultivation periods (dry season and end of the rainy season). We evaluated total productivity (t ha^-1), commercial productivity (t ha^-1), the number of fruits per hectare, the average mass per fruit (kg fruit^-1), soluble solids (°Brix), hydrogenionic potential (pH), titratable acidity (expressed as % citric acid), the ratio between soluble solids and titratable acidity (RATIO), the pulp firmness (N), as well as conducting an economic analysis. The collected data were submitted to variance analysis and the results were compared through the Scott-Knott test at a level of 5% probability, using the SISVAR software. The results indicate that the Gladial cultivar presented superior performance in terms of fruit production and quality, as well as positive economic returns. This favors the introduction of all evaluated cultivars in the northeastern region of Roraima.
