Wheat crops are affected by numerous diseases that have caused quantitative and especially qualitative losses in Transylvania conditions. The effect of treatments on winter varieties was studied in S.C.D.A. Turda during the year 2008-2009. Four variants (T1, T2, T3, and T4) were tested using combinations of foliar fertilizers, fungicides and insecticides on wheat varieties: Ariesan, Apullum and Dumbrava. The four variants were four important moments in vegetation phenology (the resumption of vegetation, and the brotherhood end phenophase and herbicidation, the bellows phenophase and the flowering phenophase). Differences between applied treatments have been observed. The best results were obtained at the T1 treatment, at the application of foliar fertilizers in all four major phenological stages: insecticide at the resumption of vegetation in the spring, at the bellows stage and at the flowering stage and fungicide at the bellows stage and at the flowering stage. The crude protein values ranged between 14.4% (T3) and 15.1% (T1) at the Ariesan variety, between 13.35% (T3) and 14.30% (T1) at the Apullum variety and between 13.6% (T3) and 14.37% (T1) at the Dumbrava variety. The wet gluten content and the Zeleny sedimentation index shows small variations between treatments, the best results have been obtained also at T1 treatment. Thus, the higher value of wet gluten content at the Ariesan variety is of 36.85% (T1), at the Apullum variety of 35.03% (T1) and at the Dumbrava variety of 35.13% (T1). For the T1 treatment, the Zeleny index has values between 49.22 ml at the Ariesan variety and 52.77 ml at the Dumbrava variety. Hectoliter mass increases through the bellows stage, the varieties T3 and T4. The foliar fertilizer treatments on the vegetation (fungicides and insecticides) provide the superior expression on biological potential of wheat varieties (production and quality).
