IMPACTO DOS INSUMOS NO CUSTO DE PRODUÇÃO DA MELANCIA

Abstract

This study aimed to analyze the influence of agricultural input use on production costs in watermelon farming in the Vale do São Patrício region, state of Goiás, Brazil. To achieve this, interviews were conducted with local producers between July and September 2024, covering information on fixed and variable costs, productivity, and revenue obtained from crop commercialization. The results showed that fertilizers and pesticides are the main components of production costs, ranging from R$2.066,11 to over R$10.330,57 per hectare, depending on the management strategy adopted. The productivity of the analyzed producers varied significantly, ranging from less than 30 t/ha to 90 t/ha. It was observed that those with higher productivity also achieved better market prices, demonstrating a direct relationship between production efficiency and product valuation. Regarding agronomic practices, all interviewed producers use drip irrigation, reinforcing the pursuit of water-use efficiency in cultivation. However, only half of them conduct soil analysis and correction, which may compromise fertilizer efficiency and negatively impact both productivity and production costs. This research highlights the importance of strategies that promote more efficient input management, allowing cost reduction without compromising productivity. The adoption of practices such as systematic soil analysis, rational pesticide use, and the implementation of integrated management techniques can contribute to increased profitability and sustainability in watermelon production. Moreover, investments in technical training and innovation can assist producers in making their crops more efficient, competitive, and economically viable in the long term. By improving agricultural practices and encouraging better management decisions, the watermelon production chain in Vale do São Patrício can be strengthened, ensuring greater economic stability for farmers in the region.
