The potato crop is very demanding regarding the presence of nutrients in the form readily available in soil solution and the climatic conditions to ensure satisfactory production of tubers. Each potato cultivar has specific characteristics for its development. The objective of this work was to evaluate the development and productivity of potato cv. Cupid, due to doses of fertilizers and the parceling of organomineral fertilization of the plantation and coverage compared to the use of the mineral. The experiment was conducted in the municipality of Perdizes, in Minas Gerais, in the harvest of 2014/15. The experimental design was in randomized blocks with a factorial scheme of 4 doses x 2 nitrogen managements + control treatment (conventional mineral dose) in 3 replicates. The doses of organomineral fertilizer were 25, 50, 75 and 100% of the mineral dose of 600 kg ha-1 of potassium sulphate, 850 kg ha-1 monoammonium phosphate, and 300 kg ha-1 of ammonium sulphate. The management of the fertilization consisted of the achievement or not of the coverage that was made at 19 days after planting (DAP) along with the hilling. At 36, 54, 64 and 81 DAP, collection of plants was performed for the characterization of potato growth. No differences wereobserved between the doses of organomineral fertilizer as well as in the management of coverage in relation to the use of the mineral. However, the dose of 75% of the organomineral fertilizer with the realization of coverage provided better physiological response of the plants in relation to the accumulation of dry mass.
