With the wide practice of using selective herbicides to protect crops from weeds and reducing available labor resources, it is becoming increasingly important to develop modern systems for protecting lentil crops edible from weeds without the cost of manual labor. Accordingly, the implementation of a scientific search for the development and evaluation of existing systems for the protection of lentil crops edible from weeds allowed the author to conclude the need for a field research system to assess the development of such a weed control system adapted to the conditions of our country. In the process of planning and carrying out field research studies, it was planned to carry out a set of observations and censuses that would allow to obtain an objective assessment of the effect of herbicides on crop plants, seedlings and seedlings of various types of weeds, the processes of contamination of lentil crops during the growing season. The purpose of research. to develop an effective system for the protection of crops of lentils from weeds by chemical methods. The task of research: to investigate the dynamics of the processes of contamination of crops: the species composition of weeds, the structure, number and mass of weeds; to investigate the factors of the negative influence of weeds on lentil plants in the process of their joint vegetation; search and evaluation in field conditions of the effectiveness of herbicides and their compositions on edible lentil crops. Research methods. Common and special methods were used: field - the study of growing conditions and winter hardiness on the performance indicators of lentils edible; laboratory - determination of quantitative and qualitative signs; statistical - the establishment of mathematical models and statistical dependencies between the studied factors and processes. Results. Weeds in crops of edible lentils are dangerous competitors for the factors of plant culture. The presence of weeds in crops throughout the growing season can reduce the level of seed yield by 86.7%. For each unit of wet weight of weeds in lentil crops, the reduction in yield level reached 0.58 g / m². In order to obtain a high yield of seeds of crops of lentils, reliable protection against weeds is imperative.
