| English abstract | The regional water balance was calculated using rainfall data collected at 14 stations located in southern Espírito Santo State and used to determine potential peanut productivity losses during two planting seasons, as well as the best period for planting peanut crops in the region, considering insufficient rainfall. The lowest and highest potential losses productivities found for the rainy planting season were 32.3 and 70.1%, respectively. The average productivity loss was 44.21%, with the best time for planting between September 1st and November 1st. Productivity losses were higher when planting during the dry season, with values of 36.9 and 85.7%, for the lowest and highest losses, respectively. Average dry season productivity loss was 56.63% and the best planting period was between January 1st and March 1st |
| Portuguese abstract | Utilizando dados pluviométricos de 14 postos de diferentes localidades da região Sul do Espírito Santo, calculou-se o balanço hídrico, por meio do qual determinou-se a perda de produtividade potencial do amendoim, em duas épocas de plantio, bem como as melhores datas para a realização do plantio do amendoim na região, com base no não atendimento hídrico por chuvas. A menor e maior perda de produtividade potencial encontradas foram 32,3 e 70,1% respectivamente, no plantio das águas com uma perda média de 44,21%, e a melhor época de plantio entre 01/09 e 01/11. Para o plantio da seca, as perdas de produtividade foram maiores, com valores de 36,9 e 85,7%, para menor e maior perda, respectivamente, com média de 56,63%, e melhor época de plantio entre 01/01 e 01/03 |
