The article presents the three-year research results of the influence of complex fertilizers and plant growth regulators, applied separately and combined with with CAS (mixture of carbamide and ammonium saltpeter solution, 30% N) on the crop yield and grain quality of oats, agronomic and economic efficiency of the fertilizers application. The action of the studied preparations on qualitative and quantitative parameters of crops is estimated: the area of a sheet surface, productivity, payback of fertilizers, weight of 1000 grains, maintenance and yield of crude protein. Different combinations of the fertilizers, plant growth regulators and CAS lead to various levels of oats crop yield, protein content and economic profitability of the oats cultivation. The calculations of the net profit and the profitability level have revealed that joint entering CAS with the studied preparations is more preferable in comparison with separate one, which is caused by the growth of the analyzed indicators
