Resumo: 	The cowpea [Vigna unguiculata (L.) Walp] is widely cultivated in Northeast Brazil and stands out for its economic and social importance. Part of the cultivation area is affected by salt stress, which affects the performance of the crop. The effects of salinity can be mitigated with the development of tolerant cultivars. The objective of this work was to evaluate the behavior of cowpea cultivars under different levels of saline stress in the germination and emergence phases of the crop. Two trials evaluating the germination and emergence phases were conducted, under controlled conditions, in a factorial scheme with 11 cultivars and five solution of NaCl with concentrations ranging from 0 to 120 mM. There was a marked difference in the response of the cultivars according to the level of salinity applied. The cultivars BRS Itaim, BRS Novaera, BRS Pajeu, BRS Tumucumaque, Sempre Verde and Pingo-de-ouro show better performance in the germination or emergency phases in conditions of saline stress, which are more promising for the initial establishment of the culture, in the presence of salinity.
