Krapovickas received a degree in 1948 in agronomic engineering from the University of Buenos Aires and began teaching in 1949 as Professor of Genetics and Systems Botany at the University of Córdoba.
[4] In 1964, he moved to Corrientes to accept a position at the National University of the Northeast (UNNE), becoming chair of its Department of Botany and Ecology in 1977.
He also founded the university's botanical gardens, Spanish: Instituto de Botánica del Nordeste or Ibone, with his wife, Dr. Carmen L.
[5] Krapovickas' research centered on taxonomy of the family Malvaceae and biology of species in the genus Arachis (Fabaceae).
His publications in these fields, including over 110 papers, 8 book chapters, and a monograph on Arachis - the genus of the groundnut - that he coauthored with Walton C. Gregory, are very influential and widely cited.
