Chukhina O. V., Tokareva N. V. Infl uence of fertilizers on nutritional value of vetch and oats mixture

9

УДК: 631.582:631.816.1

The presented data shows the influence of various fertilization rates on vetch and oats mixture’s green mass productivity, its nutrient composition and exchange energy. It is also shown that the designated fertilization rates increase the green mass productivity of the mixture by 36-46 %, its crude protein yield by 170-238 kg/hectare, and exchange energy content by 11,4–14,3 GJ/hectare. At the same time the sugar to protein ratio corresponds to the optimum value of 0.9–1.0:1.0.

Keywords: vetch and oats mixture, fertilizers, green mass, crude protein, fat, cellulose, ash, exchange energy.
