Abstract

Purpose. To investigate the germination features and sowing properties of seeds of the Danaya creeping trefoil, Vilia hybrid clover, Ajax Lotus corniculatus varieties. To establish the features of improving the sowing properties of seeds, in particular, germination energy, viability, and spread by the seeds pathogenic microorganisms damage reducing. Methods. Measuring, visual, quantitative, laboratory, mathematical and statistical. Results. The method for pre-sowing improvement of sowing properties of the creeping trefoil and hybrid clover seeds has been developed by treating them with the bacterial preparations Rizobofit (strain of the bacterium Rhizobium leguminosarum biovar trifolii) and of Lotus corniculatus (strain of the bacterium Mesorhizobum loti) in the amount of 0.15 l per hectare seed normative or treating them with the Ahrohumat anti-stress agent – 0.2 l/t of seeds, which contributes to the increase in germination energy by 6-9%, viability – by 7-10%, and spread – by 5-10%. Conclusions. The influence of pre-sowing treatment of seeds of pasture leguminous grasses on the formation of sowing qualities of the creeping trefoil, hybrid clover and Lotus corniculatus has been established. It is effective to Treating the seeds with the bacterial preparation Rizobofit strains depending on the legume variety (150 ml per hectare norm of seeds) or the anti-stress agent Agrogumat (200 ml / t of seeds) showed its effectiveness, it contributed to the increase in germination energy, viability and growing power of seeds by 6-9, 7-11 and 5-10%. Growth regulators Saprogum (70 ml/t) and Biosil (25 ml/t) were somewhat less effective, the indicators were 3-5% lower compared to the other above mentioned preparations.
