This paper examined the effect os soil type, start fertilization with NPK fertilizers and row spacing on the productivity of buckwheat. Field microexperiments were conducted in the agroecological conditions of South Banat on tchernozem soil type and in Šumadija (Central Serbia) on brown forest soil type. The applied amounts of fertilizers expressed in kg ha-1 of active substance, were: Control (unfertilized), NPK 30:30:30, NPK 60:60:60 and NPK 90:90:90. Sowing of buckwheat was carried out on 25 cm and 50 cm row distance. Obtained results showed statistical differences between the parameters of productivity depending on soil type, applied amounts of NPK fertilizers and vegetation area shape. The interdependence between examined factors was determined.
