Abstract

The purpose. To study influence of presowing treatment of seeds of leguminous ingredient and fertilizer system on fodder productivity of Lucerne-cereal grass mixture. Methods. General scientific and special: field, laboratory, design, mathematical-statistical. Researches were spent by laboratory of fodder production and agroecology of Ternopil experimental station of Institute of veterinary medicine of NAAS on dark grey podzolized soils with average loamy mechanical grading. Scheme of experience included 3 factors: factor A — treatment of seeds, factor B — doses of fertilizers, factor C — foliar top dressing. The grass mixture consisted of Medicago sativa L. of grade Siniukha, Bromus inermis Leus. of grade Mars, Festuca arundinaceae Schreb. of grade Lyudmila. It was formed in view of results of researches of scientists of Institute of fodder crops and agriculture of Podillia of NAAS. Foliar top dressing with Triamin Plus was made in the beginning of aftergrowing of each hay cutting (BBCH 31 for Lucerne and BBCH 21-22 for cereal grasses) at presence of sufficient leaf area in dose of 2 l/hectare and charge of working solution of 250 l/hectare. Mowing of grass mixture was carried out at approach of maturity of perennial grasses (Lucerne — initial blossom — BBCH 60, gramineous plants — initial blossom — BBCH 49-51). Results. Influence of fertilizer system and presowing treatment of seeds of leguminous component on fodder productivity of Lucerne-cereal grass mixture is determined. Conclusions. In conditions of natural humidification of Western Forest-steppe on dark grey average loamy soils use of presowing treatment of seeds of leguminous component, entering phosphoric-potash fertilizers in dose of P60K60 and foliar top dressing with Triamin Plus in dose of 2 l/hectare in the beginning of formation of each hay cutting provide the greatest productivity of Lucerne-cereal grass mixture — 10,41 t/hectare of dry matter, 7,97 t/hectare f.u., 101,2 Gjoule/hectare of exchange energy and 1,24 t/hectare of digested protein.
