There was showed the methods of the simultaneous herbicide and urea sprayings of winter wheat variety Almari, and noted that the efficiency of this was depend on the intervention kind and the usable solution concentration. Aminopielik D application (3 cubic dm/ha) was increased grain yield only to compare with plants fertilized with urea (in dose 46.6 kg/ha) solution and great concentration of this - 100 cubic dm/ha. The nitrogen fertilization in urea solution, mostly increased protein content in wheat grain and protein yield. The most efficiency was the nitrogen fertilization applied together with the plants protection and with the solution concentration 200 cubic dm/ha. There was increased grain yield about 0.53 t/ha to compare with plants sprayed only with urea or Aminopielik D. The highest grain yield (6.7 t/ha), with high protein content and the same more valuable yield, was with simultaneously nitrogen fertilization and plant protection with low concentration of usable solution (400 cubic dm/ha)
