Abstract


The objective of this work was to evaluate the effect of two potassium products applied via leaf on the production and quality of fruits of the Marli variety cultivated in Nova Pádua, Serra Gaúcha. The treatments used were: T1 (control, spray with water), T2 (spray with Ubyfol K 50 + S) and T3 (spray with Amino Quelant - K). Regarding the results, the potassic leaf fertilizations did not significantly influence the analyzed parameters, such as soluble solids, acidity, color, pulp firmness, productivity, fruit size and mass. However, a negative effect on the number of fruits per plant was obtained.
