Abstrakt: The research was carried out in the period 2021-2022 at the Research Development Station for Plant Culture on Sands Dăbuleni, Romania with the objective of the behavior of 16 cowpea genotypes (Vigna unguiculata L. Walp), in the conditions of sandy soils in the south of Oltenia. The obtained results highlighted the specificity of the cowpea for thermohydric stress, the plant tolerating very well the specific microclimate created by the recent climate changes. Thus, the tested cowpea genotypes recorded at plant maturity a number of 7.7-15.7 pods/plant and grain production values in the range of 1413.5-3065.5 kg/ha, highlighting a distinct correlation significant between the two components (r = 0.703**). The cowpea lines 27-B-3a, 27/2 and 25-A1-3 stood out, with the highest grain productions (2928.6- 3065.5 kg/ha). [ABSTRACT FROM AUTHOR]
