The research conducted during the period of March to October 2019, at the Meadows Research and Development Station, Vaslui (46°40'-36°10' north latitude and 27°44'-20°40' east longitude) followed the influence of fertilization and the distance between rows on the plants' height (cm), shoots number (shoots·m-2) and inflorescences number (inflorescences·m-2), at sainfoin (Onobrychis viciifolia Scop.) seeds culture, in the first year of vegetation. The organized experience was bi-factorial, 3x5 type, placed according to the method of subdivided plots, with the plot harvestable area of 13.5 m2 (1.5 m x 9 m), in three replications, and the studied factors were: A - the distance between rows with three graduations (a1 - 25 cm, a2 - 37.5 cm and a3 - 50 cm) and B - fertilization with five graduations (b1 - unfertilized, b2 - N50P50, b3 - N50P50K50, b4 - N100P100K100 and b5 - cattle manure 20 mg·ha-1). Resulting from the study, it was found that by applying mineral or organic fertilizers and by sowing at smaller distances between rows higher plants were obtained, with a higher number of shoots·m2.
