Sowing density is very important to ensure the optimum nutrition at the area of crop plants, in order that the production of quality of barley. On the other hand, the time of sowing is very important in how the plants resistant to the environment in winter and to the attack of pathogens and pests, by spring. Experience presented in this paper, shows how sowing density and sowing time influences the production of barley, of Cardinal variety in the climatic conditions of the agricultural year 2012 - 2013, Chiscani Experimental Center, the Agricultural Research and Development Station of Braila on a typical chernozem soil type. For this, we used seven experimental factor graduations for sowing density and five experimental factor graduations for sowing time. During the vegetation were made biometric measurements on plant height, number of leaves per plant, number of grains per ear, grain weight per ear and yield of each experimental plot at harvest. Based on the results, and analysis of variance were performed for the two experimental factors and correlations were established between the experimental factors and biometric measurements. Synthesis results show that the experience of winter barley crop in the climatic conditions of Braila, the best sowing density is 550 g.s/m2 and optimum sowing period is 3-20 October.
