Faced with the problem of disposing of liquid waste, the possibility of using this waste as potential fertilizer is noted. The present study aimed to evaluate the potential of sugarcane bagasse ash as an alternative organic fertilizer. The study was conducted in pots with a volume of 8.5 liters, in field conditions, in a 2 x 6 factorial scheme (two cultivars x six treatments), and five replications, totaling 60 plots. The treatments were designed using 0%, 25%, 50%, 100% and 150% recommended dose per hectare (based on Potassium) and an additional control with conventional NPK fertilization. Variables of the plant part and seeds harvested from the experiment were analyzed, comparing the differences between cultivars and different treatments. There was no variation as a function of treatments in the amount of lipids, but there was a difference in carbohydrate levels. The Caiana cultivar has seeds of superior qualities than the Tatu ST cultivar, being the most recommended for use in animal feed. The sugarcane bagasse ash is a good source of nutrients, however, it is recommended to repeat the experiment under other conditions to confirm its potential as fertilizer.
