Being a plant with considerable agronomic qualities, soybean returns to farmers attention (Dencescu et al.,1982b; Ionescu, 1985). Indeed the new varieties have improved by characters: high production potential, quality and constantly over time (Gallais & Bennerot, 1992). In exchange for use of these qualities are needed informations about how to adapt plants in different ecological areas (Giosan et al., 1986). Given white luvicsoil in South the plant finds a good regime of sufficient rainfall and temperature (Ionescu et al., 1986; 1994). Against this background proved to be important the specific crop system. 2.0-3.0 t.ha-1 yields were obtained while during the filling of the grains fell 150-200 mm water. During the growing season of 100-140 days have accumulated 1200-14000C temperatures above 100C. Among during the growing season and grain production achieved a positive correlation (r=0.591***) so that varieties with higher period during the growing season formed the best production. Plant morphology: size, number of pods per plant and grains were positively correlated with grain yield. Negative correlations were obtained between the thousand grains weight-TGW with production of grains, TGW with grain number per plant and between fat content with the content of crude protein of the grain. Production levels achieved over the years has been between 1.06 and 3.49 t.ha-1 like limits. Among the crop items highlighted technological density peaks at 60-80 seeds.sq.m-1.
