Abstract: 
The purpose of this paper is to evaluate the soybean yield obtained from the application of the additional fertilization and economic efficiency determination. Experimental factors: Factor A - the fertilization: a1-N20P20K0 (100 kg/ha), applied simultaneously with sowing, a2-N20P20K0 (100 kg/ha), applied simultaneously with the sowing + N20P20K0 (100 kg/ha), applied in the 4-6 leaves phenophase, a3-N20P20K0 (100 kg/ha) applied simultaneously with sowing + N30 (100 kg/ha), applied in the 4-6 leaves phenophase and a4-N20P20K0 (100 kg/ha) applied simultaneously with sowing + N20 (100 kg/ha), applied in the 4-6 leaves phenophase; factor B - soybean varieties: b1-Mæalina TD, b2Darina TD, b3-Felix and b4-Onix; factor C - climatic conditions in the experimental years: c1-2015; c2-2016; c3-2017. By applying additional fertilization are obtained a very significant yields of over 120 kg/ha. The Mæalina soybean variety achieved an average yield of 2706 kg/ha, in the period 2015-2017, with differences significantly higher than the other three varieties studied under the same conditions. The thermal and pluviometric regime is an important factor in determining the yield of a crop, in 2015 was obtained an average yield of 1912 kg/ha, and in the years 2016 and 2017 achieved the yield of 3447 kg/ha respectively 2329 kg/ha, with significantly higher differences than in 2015. The yield of the four varieties is in direct relationship with the level of fertilization.
