Rapeseed is a crop that has a significant agronomic response in terms of seed yield and oil content and yield. This study aims to assess the influence of fertilizer type, quantity and the combined effect of them on both seed and oil yield in the pedoclimatic conditions of Western Plain in Romania. The research was carried out on a chernozem soil with a weak acidic reaction and for biological material, it consisted of one rapeseed hybrid developed by Limagrain company, Astronom. The experimental field was uniformly fertilized at the same time with sowing with 200 kg/ha of 27:13.5:0 complex fertilizer and in order to assess the influence of fertilizers, in the spring, three graduations of fertilizers were used, as follows: a1 - E34 (10:24:0 + 0.1Zn + 0.1Br +20 SO3); a2 - DAP (18:46:0) and a3 - 20:20:0. The results highlight the increase of both seed and oil yield, depending on the type of the fertilizer, with as much as 20% compared to the field average.
