Efficiency of winter barley cultivation methods for herbage for bulk feed conservation

The article presents the results of economic and bioenergetic assessment winter barley cultivation methods for harvesting bulky fodder. In a short-term experiment effect five levels mineral nutrition on two tillage in crop rotation link soybean – barley, fused leached chernozems southern foothill zone Adygea has been studied. Differentdepth have used 20–22 cm (plowing) 12–16 (surface tillage). As background variants, main fertilizer ammophos ammonium nitrate as top dressings (N30; N45; N60). It revealed that use surface treatment reduces yield green mass by 21-41%. average varied from 8.8 to 12.8 t/ha plowing. highest level productivity is 19.2 plowing 12.0 treatment. studied varieties 1 kg natural feed contains, average, 0.42 0.605 EFU (energy units). Analysis nutritional value obtained shown: dry matter plowing: crude protein 10.1%, exchange energy 11.72 MJ, units (Ke) 1.12; 8.8%, 1.13 (Ke). formed according method, with introduction 60 a.i. N (N24 P104) most profitable option is: Background + N60 (Romans variety), t / ha, profit sale 10603.8 thousand rubles, profitability 58.3%. Bioenergetic shown each unit invested production mass, best options, 2.75 2.92 obtained.
