During the period 2015 - 2107 in the experimental field of the OSC Pavlikeni, in non-irrigated conditions, a demonstration experience with 25 our and foreign soybean varieties of different types of maturity, was carry out. In a tabular and graphical form, yields of soybean grain are presented according to varieties, years and average for the period, sorted in ascending order according to the length of their growing period (GP). It has been established that the foreign varieties are of a GP length not satisfying their variety characteristics, most often it is larger. For our conditions, the most suitable and the highest yields are the varieties of group maturity II: medium-early with GP from 120 to 130 days. The highest yields by region of origin were obtained from: Bulgaria, followed by varieties originating in Slovakia, Romania, France, Germany and Serbia. Avigeya is the first variety with average yield was 226 kg/da. Followed the varieties Gladiator, Atlanta and Cristine with yields were about 200 kg/da, originate from France, Slovakia and Germany respectively. A strong relationship (R2 = 0.94) between the “grain harvest index” and soybean yield is established which can be used as selection criteria for assessing the productivity of newly created lines and candidate soybean varieties.
