Yamkova V. Fodder efficiency of corn and legumes as consistently crops cultivated for silage in a right bank forest-steppe

Object of research - the process of formation productivity of plants in single-species and hybrids of maize crops compatible with beans fodder and soya beans, depending on hydrothermal conditions in the region, density and species composition of plant crops. The purpose of research - scientific studies, development of elements of growing technology compatible crops different-ripe hybrids of corn with fodder beans and soya beans and silage to determine their impact on forage production and forage quality in Forest right bank. Research methods - field, laboratory, chemical, biochemical, mathematical-statistical, comparative-tlement. Results - the dissertation investigates the influence of density and species composition of legumes and corn with different groups of ripeness as compatible crops, on plant growth and development, on plant dimension and mass accumulation, on amount of dry substance and assimilation surface, net photosynthesis productivity, yield and nutritional value of the mixed crops, changing water and nutrient regime of the field soil, in a right-bank forest-steppe. It was estimated the economic and bioenergetic efficiency of cultivated compatible crops: different-ripe hybrids of corn with fodder beans and soya beans, depending on bean component density. High yield of silage mass was formed with consistently crops of maize hybrids mid Comet CF and soy bean component with density of 220 thousand plants/ha - 54,0 t/ha. Economic and bioenergetic estimation of conditional net profit in this version was 8886 UAH/ha, the profitability of 180 % and energy efficiency ratio - 3,12. Introduced in farms of the Kiev's region of the total area of 130 hectares. A sphere of the use is agriculture.
