ABSTRACT - 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.

RESUMO - Curvas de acúmulo de macronutrientes em genótipos de batata no Cerrado brasileiro - O conhecimento das demandas nutricionais dos diferentes genótipos  de  batata  é  necessário  para  o  desenvolvimento  de  recomendações de fertilização. 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. 

PALAVRAS-CHAVE: Solanum  tuberosum,  absorção  de  nutrientes, adubação parcelada.</abstract>
