Resumo: | Knowledge on the nutritional demands of different potato genotypes is necessary for the development of fertilizing recommendations. This study aimed to determine and compare the macronutrient accumulation curves in the Agata, Asterix, BRSIPR Bel and F183-08-01 potato genotypes, in order to subsidize the split fertilization that could meet the specific demands of each genotype. A randomized block design was used, with the treatments (genotypes × plant stages) arranged in a split-plot scheme, with three replications. The genotypes were grown in plots containing 75 plants each. The subplots within a plot contained four plants each and corresponded to the number of days after planting, when destructive samples of whole plants were collected. The plants from the subplots were harvested at 24, 38, 52, 66 and 80 days after planting, to estimate the dry mass accumulated by different parts of the plant (shoots + roots, tubers and whole plants), as well as to determine the macronutrient accumulation curves. F183-08-01 presented the highest total accumulation of N, Ca, Mg and S (141.37, 29.21, 25.16 and 22.36 kg ha-1, respectively). The highest rates of macronutrient accumulation for all the potato genotypes occurred at 24 days after planting, coinciding with the beginning of the tubers formation. KEYWORDS: Solanum tuberosum, nutrient uptake, split fertilization. |

Objetivou-se determinar e comparar as curvas de acúmulo de macronutrientes nos genótipos de batata Agata, Asterix, BRSIPR Bel e F183-08-01, visando subsidiar o parcelamento de adubação que atenda as demandas específicas de cada genótipo. O delineamento foi em blocos casualizados, com os tratamentos (genótipos × estádios de planta) dispostos em esquema de parcelas subdivididas, com três repetições. Os genótipos foram cultivados em parcelas contendo 75 plantas cada. As subparcelas dentro de uma parcela continham quatro plantas cada e corresponderam ao número de dias após o plantio, quando amostras destrutivas de plantas inteiras foram coletadas. As plantas das subparcelas foram colhidas aos 24, 38, 52, 66 e 80 dias após o plantio, para estimar a massa seca acumulada por diferentes partes da planta (parte aérea + raízes, tubérculos e plantas inteiras) e para determinar as curvas de acúmulo de macronutrientes. F183-08-01 apresentou o maior acúmulo total de N, Ca, Mg e S (141,37; 29,21; 25,16; e 22,36 kg ha-1, respectivamente). As maiores taxas de acúmulo de macronutrientes para todos os genótipos de batata ocorreram aos 24 dias após o plantio, coincidindo com o início da formação dos tubérculos.
