The study analyzed how elements of crop management can contribute to increasing the yield of the winter rape crop. Field research took place in the area of Satu Mare locality, Arad County, Romania, in the period 2022-2023. The field experiments were organized in farm conditions, with accessible agricultural technologies. Two soil working systems (Sws) were considered: a classic system of soil preparation by disc tillage (SwsA), and a system of soil preparation by direct seeding (SwsB). Four treatments (T) of nitrogen and sulfur fertilization (T , T3 and T4) were applied to the background of each system, compared to a classic fertilization (T2). In the case of soil tillage SwsA system, rape yield average was Y(AvgSwsA) = 3,537.50 kg ha- (T4 treatment generated increase yield, Y = 380.50 kg ha- ). In the case of soil tillage SwsB system, rape yield average was Y(AvgSwsA&B) = 3,795.00 kg ha- (T4 treatment generated positive growth, Y = ,007.00 kg ha- ). At the experiment level, the average yield was Y(AvgSwsB) = 3,666.25 kg ha- . A significant yield increase was recorded only in the case of the T4 treatment, with Y(SwsB-T4) = , 35.75 kg ha- . Multiparameter analysis (PCA, CA) facilitated distribution diagrams and classification of variants, under conditions of statistical safety (Coph.corr = 0.936). PC explained 40.35% of variance and PC2 explained 29.297% of variance. Mathematical models described the variation of yield (Y) in relation to biometric parameters of the plants (p<0.00 , R2 = 0.873 to R2 = 0.989).
