Abstract
Alfalfa (Medicago L.) is widely used throughout the world as a valuable fodder, leguminous crops. However in Kazakhstan there is not enough crop acreage for a number of reasons. Various agrotechnological methods have been developed to increase seed germination, productivity, crop quality, survival, and adaptation. One such method makes use of biological preparations. This article presents the results of studying the effects of pre-sowing treatment of alfalfa seeds on sowing qualities. Preparations used: BioSleep BW+Foliar, Orgamica S+Foliar, OrganitN+ OrganitP+ Biodux+Foliar and Foliar. Operating fluid consumption for treatment was 0.2 ml per 100 g. During the treatment, germination energy increased by 5-20%, laboratory germination by 4-13.5%, field germination by 1-10%. BioSleepBW+Foliar preparations showed the highest result in terms of germination energy – 75.3%.Laboratory and field germination are more effective in the variant with OrganitN+ OrganitP+Bidux+Foliar preparations – 84% and 50%, respectively.Thus, use of biological preparations significantly increases the germination energy, laboratory and field germination of alfalfa seeds.
