Abstract

Sugarcane juice from NA 56-79 variety at four maturity stages (4, 6, 8 and 12 months) fertilized with vinasse was analysed for potassium and trans-aconitic acid content. With vinasse fertilization there was a significant reduction in total reducing sugars and an increase in potassium and trans-aconitic acid content of sugarcane juice. A significant positive correlation was observed between trans-aconitic acid production and potassium content. Trans-aconitic acid content was inversely related to the plant maturity.
