Leguminous crops are becoming increasingly important in our country and on planet Earth as. This trend is due to the high quality of seeds, as well as the ability of plans to bind nitrogen from the atmosphere, and therefore they are one of the best predecessors in crop rotation. The aim of this research was to identify the effectiveness of applying soil and insurance herbicides at growing lentil seeds, the effect of combined use of drugs on the seed productivity of lentil plants, the aftereffect of these drugs on the sowing performance of lentil seeds. The following methods were used in the research process: field and one factor experience - for biometric measurements and crop yield accounting; laboratory method - analysis of the structure of plants and the quality of the seed crop; calculated - assessment of the economic and energy efficiency of growing crops, payback of material and natural resources; statistical - carrying out analysis of variance and statistical processing of research results. As a result of the research, it was found that under the influence of soil and insurance herbicides on lentil crops, the possibility of obtaining conditioned crop seeds increases. Analysis of the data shows the effectiveness of the use of soil and insurance herbicides, as well as their mixtures in different doses.
