In the guidelines for increasing protein content in food population and animal at national and international level, the basic concern is the exploitation of soils in arid and semiarid climates by adapted crops ecopedological specific conditions that contribute to reduced negative climate change and sustainable agriculture. In this research at Research -Development Center for Field Crops on Sandy Soils Dabuleni during 2004-2011 aimed to reduce the negative effect of drought in the area psamosoils by the potential biological cowpea a specific plant arid climate. The results obtained show that the cultivation of cowpea Ofelia and providing sown an area of plant nutrition 20 germinable seeds/m2 can successfully capitalize on sandy soils of low natural heritage. Rational fertilization by N60P60K60 and applying fractionated nitrogen (1/3 sowing + 2/3 vegetation) resulted in the best production results (2752 kg/ha), due to optimization of plant physiological processes. In this experiment there was a maximum of the photosynthesis process, the CO2 28.34 micromoles/m2/second and minimum consumption of water through perspiration, the 2.26 millimoles H2O/m2/second.
