Сhemical composition, nutrient and energy content of feed biomass from triticale yargo and peas for different technologies of co-cultivation

Aim. To establish indicators of chemical composition, nutrition and energy intensity spring triticale seed pea in single-species compatible crops depending on the ratio components fertilizers. Methods. Field, laboratory, mathematical-statistical, analytical. Results. The results studies composition fodder annual binary agrophytocenoses with participation different ratios fertilizers black earth soils Forest Steppe, which were conducted annually during 2020–2022, are shown. Conclusions. inclusion peas leguminous-cereal mixture improves feed, increasing content crude protein dry weight feed from 12.9 to 14.8−16.3%, or by 1.9−3.4%. At same time, fat mass increases, digestibility vitro − 3−7%, nutritional value according units, exchangeable supply one unit digestible 83 112−128 g, raw ash 0.3−0.6%, calcium 0.06−0.10%, magnesium 0.01−0.06%, Ca:P fiber decreases 1.5−3.1%, potassium K:(Ca+Mg) ratio. With introduction humigran triticale, their crops, increases 1.4−2.0%, – 0.4−1.9%, N45P45K45 1.4−2,5% 0.8−2.4%. Under influence these fertilizers, fat, energy, protein, forage simultaneously non-nitrogenous extractive substances all grass stands.
