The melon crop (Cucumis melo L., var. Valenciano Amarelo) represents an important contribution for the total Brazilian exportation products. Carbon dioxide concentration was assumed to be 250u-molCO, . mol-1 before industrial revolution, achieving 3l5 u molCo2.mol-1 in l958. Nowadays it is approximately 365 u molCO2 . mol-1, with tendency of increasing. In this research was evaluated the effect of carbon dioxide application through irrigation water on melon fruit productivity and chemical characteristics. The trickle irrigation system was used. The industrial and purified carbon dioxide applications were daily and three times a week, in three different types of crop management as lateral protection, mulching and soil without protection. The carbon dioxide application through irrigation water did not alter the melon crop season, and it did not affect the fruit chemical characteristics, such as soluble solids content, total acidity and pH. The highest yields were obtained with carbon dioxide application through irrigation water
