Abstract

In order to achieve an efficient system of agriculture in sandy soils of southern Romania and promote sustainable agriculture, must be found that species of plants that are more easily to thermal-hydr conditions in this areas. Cowpea (Vigna unguiculata L. Walp), is one of the plants which recover very well the specific climatic conditions of the area psamo-pelitic soils in southern Romania, being a plant resistant to drought, with reduced requirements to soil fertility.The results obtained during the 2009-2015 from Development Research Center for Plants Crops on Sands, Dabuleni, Romania, concerning the behavior of 144 genotypes of cowpea, revealed variability of the species, in terms of morphology and plant productivity. Of the 144 genotypes studied, 38% allow selection for obtaining varieties of cowpea for grains, 26% allow for selection of genotypes of cowpea for feed, and 36% allow selection of obtaining genotypes for green manure. Grain yield obtained from cowpea was negatively correlated with rainfall.
