Abstract: The trials were carried out on the experiment Station at Lithuanian University of Agriculture over the period 2002-2004. The soil of the experimental station at Lithuanian University of Agriculture is IDg8-k (LVg-p-w-cc) (Calc(ar)i-Epihypogleyic Luvisols).The efficacy of the different fertilizers (five complex ARVI fertilizers (the composition of which would include nitrogen, phosphorus, sulphur and microelements) in the setting of five different pesticide applications: 1. Teridoks 2,5 1 haˉ¹; 2. Karate 0,2 1 haˉ¹; 3. Amistar 0,5 1 haˉ¹; 4. Teridoks 2,5 1 haˉ¹ + karate 0,2 haˉ¹; 5. Teridoks 2,5 1 haˉ¹ + Karate 0,2 1 haˉ¹ + Amistar 0,5 1 haˉ¹. Application norm of each fertilizer so that not less than 135 kg haˉ¹ of nitrogen would be applied. The comparision of the efficary of complex fertilizers revealed, that higher yield additions were obtained where fertilizers. Containing more nutritions elements were applied. Optimum summer rape fertilization norm - Ni35P8oKno- Complex fertilizers NPK 17-10-14+Sn irNPK 13-10-15 + S8+Mg5, applying 800 and 1000 kg ha"! respectively were found to be the best for the fertilization. Different pesticides and their combinations were shown to substantially affect the efficacy of the mineral fertilizers. The highest efficacy was obtained on only highly cultivated soils
