ABSTRACT
Potato is a plant that has high nutrient demand during its cycle. Given the concern with the environment, due to the large amount of synthetic mineral fertilizer used in the crops, the objective of this work was to evaluate the efficiency of organomineral fertilizers in the cultivation of potato, cultivar Ágata, under cerrado conditions. The experimental design was in subdivided plots, consisted of four doses of organomineral fertilizer, corresponding to 40, 60, 80, 100 and 120% of the mineral fertilizer dose in the organomineral source (2800 kg ha-1 of formulated 3-32-6) and the subplots consisted of four collection seasons (61, 74, 89 and 110 days after planting) and four repetitions. Organomineral fertilizer with 40% of the recommended dose for potato cultivation provides higher yield of tubers in the Especial potato class and higher accumulation of total dry mass, in addition to providing satisfactory productivity for the tubers of higher commercial value. The use of organomineral fertilizers promotes the same behavior as mineral fertilizers, not interfering with potato development.
