Abstract
The study of ecological adaptability of different economic and biological indicators of intensive varieties of grain and leguminous crops for use in feed grain-grass crop rotation is aimed at increasing the production of high-quality concentrated feed. Objects of research: intensive varieties of spring wheat, barley, lupine (yellow, narrow - leaved and white), peas (sowing and field-PELs) and soybeans. In 3 experiments 13 varieties of spring wheat, 7 varieties of spring barley and 16 varieties of 6 types of legumes were studied. It was found that the adaptability of spring wheat, barley and peas against the background of intensive technology on a set of indicators above other cultures. The main stressor wheat varieties in the experiments, the deficiency of moisture and heat in the initial period of the growing season, spring barley - diseases (rust, leaf spot) pea pests (pea moth), Lupin, weeds and diseases, soy - sensitivity, lack of heat, weeds and disease.. On intensive soil fertility varieties of spring wheat «Lyubava», «Kamenka», «Madam», «Zlata» and «Rook» shaped grain crop at 7.3-8.0 t/ha, spring barley «Reliable» - 7.0 t/ha and peas «Before-100”-3,4 t/ha. the results of the comparison of the chemical composition and nutritional value of grain of different crops varieties have confirmed a special feeding value of soybean (14.5 and 15.3 MJ of energy; of 37.8-42.8 % of crude protein; The 17.8 was 23.0 crude fat in 1 kg DM), high contents of certain nutrients in the grain, other kinds: crude protein in yellow lupine (41,0 %) and white (of 37.3 and 39.9 %, respectively), starch - in cereals and peas (38,5 vs. 50.6 %), crude fiber - blue lupine (14,5-22,1 %), especially in determinantal varieties (of 20.9-22.1 per cent). Leguminous cultures were allocated by the greatest maintenance in grain of nitrogen, phosphorus and potassium, and grain cultures - carrying out them with a crop. The grain of all kinds of lupine calcium content of the highest (3.8-5.5 g/kg), the lowest - in peas and wheat (0.8-1.1 g/kg BW).
