THE EFFECTIVENESS OF AMINO ACID BIOSTIMULANTS IN ENSILING MAIZE
The results of three-year studies on the effectiveness of amino acid biostimulants in silage of different maize hybrids grown in the Smolensk region are presented. Growth promoters have recently become increasingly popular. Growth promoters provide improved quality of agricultural products. Economic benefits from the use of synthetic growth promoters greatly exceed the costs of their acquisition. After organoleptic evaluation of silos the best indicators were hybrids Voronezh 160 CB and P 7054 in the processing of amino acid biostimulants - these samples had a pleasant fruity smell compared to the control samples. It is shown that the use of amino acid biostimulants in the silage of corn contributed to the increase in the content of lactic acid in the silage mass, crude protein. The influence of amino acid biostimulants on the acceleration of growth rates was studied, which increased the fiber content in all variants of the experiment. The use of amino acid biostimulants Amino-zinc, Biostim Rost, Fertigrein-Folian contributed to better conservation of energy in the dry matter. In terms of profitability, the same options had advantages. The most significant profitability was in the variant Amino-Zinc, the processing of maize hybrid Voronezh 160 СВ relative measure of economic efficiency made 169,4 %, in the processing of hybrid P 7054 170,7 %.
