Abstract

The use of humic substances, amino acids and marine algae extract can help in increasing sugarcane photosynthetic and metabolic efficiency, with effects on productivity and industrial quality. In this study it was evaluated the effect of the foliar feeding of two commercial products containing humic substances, amino acids and marine algae extract, on the nutritional efficiency, industrial quality, and yield of RB867515 variety sugarcane. It was conducted in two 10.0 ha fields, with the products applied in one field and not in the other (control). The commercial products were applied in 4.0 l and 5.0 kg doses per hectare to re-growth foliage sixty days after cutting the cane-plant when the plants presented an average height of 80 cm. Ten months after applying the products, ten samples were collected from each field to assess the juice quality and sugar production. Applying the products did not influence nutritional efficiency and industrial quality, but did increase stem productivity, since the average for the control field was 126.8 kg ha-1, whereas for the field where the products were applied it was 166.3 kg ha-1.
