Resumo: 	ABSTRACTThis study aimed to evaluate the effects of the application of two types of oil drilling wastes on the development and absorption of barium (Ba) and sodium (Na) by sunflower plants. The waste materials were generated during the drilling of the 7-MGP-98D-BA oil well, located in the state of Bahia, Brazil. The treatments consisted of: Control – without Ba application, comprising only its natural levels in the soil; Corrected control – with fertilization and without wastes; and the Ba doses of 300, 3000 and 6000 mg kg-1, which were equivalent to the applications of 16.6, 165.9 and 331.8 Mg ha-1 of waste from the dryer, and 2.6, 25.7 and 51.3 Mg ha-1 of waste from the centrifugal. Plants cultivated using the first dose of dryer waste and the second dose of centrifugal waste showed growth and dry matter accumulation equal to those of plants under ideal conditions of cultivation (corrected control). The highest doses of dryer and centrifugal wastes affected the development of the plants. The absorption of Ba by sunflower plants was not affected by the increase in the doses. Na proved to be the most critical element present in the residues, interfering with sunflower development.
