Abstract

The purpose. To increase feed productivity of Lucerne depending on application of inoculation of seeds and soil liming at naked way of sowing and application of herbicide. Methods. Systems analysis, field, laboratory, mathematical-statistical, comparative-calculation. Soil cultivation — conventional for zone of Forest-steppe. Calculation of dose of CaCO3 was carried out according to hydrolytic acidity. Weed control spraying — by herbicide Picador in dose of 1,0 l/hectare — was used in the phase of 3-4 ternate leaves. Results. It is fixed that application of bacterization of seeds of Lucerne and soil liming on hydrolytic acidity promoted heightening of productivity of grass stand at mowing of three hay cuttings in budding stage and one — in the beginning of flowering. The greatest yield of feed units and crude protein have gained at inoculation of seeds with Rizobofit in combination with Emistim S and importation of full dose of lime on hydrolytic acidity. Obtained data testify to unconditional efficiency of use of probed factors at growing Lucerne for feedstuff. Conclusions. Perspectives of use of Lucerne of intense type as major factor of production of high-protein feedstuffs and biological nitrogen as result of its symbiotic fixing from air that will ensure increase of fertility of soil and saving means for fertilizers is justified. For creation of powerful grass stand and heightening productivity of Lucerne it is expedient to inoculate seeds with biological preparations and lime soil at naked way of sowing Lucerne with importation of herbicide.
