The experiment was carried out  within the Didactic Station of USAMVB Timisoara on a cambic chernozem slightly gleyied, slightly hyposalic  and moderately hyposalty under 100 cm, slightly decarbonized  on loess moderate  fine deposits   medium  clay loam / medium clay loam. According to its composition, the soil falls within the class   texture "fine textured”, subclass medium clay loam, undifferentiated in profile. In the first part of the profile the soil reaction is neutral (pH 7.03-7.18) and in the second half the reaction is   slightly alkaline (pH 8.25-8.49). The reserve of humus is low (62.98-75.65 t / ha) in the processed horizon and very low   under 60 t / ha for the underlying horizons. Trifactorial experiments were carried out in the two cultures, in which the factor A, was represented by the cultivated variety   ((for pea Dosa, Montana and Monique, for soybean Felix, Neoplata and Venera), the  factor B –  represented bacterized - non bacterized, and the factor C  represented  the sowing period with two graduations. Among the tested pea varieties   Monique was the best because it had a yield of over 1950kg/ha, as compared to the experimental factors. The results obtained in the soybean culture of the Timis Plain bring out the Neoplant and Verena varieties, which had higher yields with 16% and 27%   than those registered for the Felix variety. The difference in yield of 318 kg / ha, 515 kg / ha respectively, is statistically very significant. These conclusions must be verified in future years, having in view   the registered climatic irregularities in 2009. The results obtained are in favour of increasing the cultivated area of the two tested leguminouse species. This relies on the assertion that for the extension of the nonpolluting technologies within the rotation of crops we have no solutions for giving up the leguminous cultures, even if the yields are low as their economical and agricultural value make them irreplaceable.
