This article provides information on the effect of sowing 2.0, 3.0, 4.0 million germinated seeds of lentils "Darmon" in autumn and spring on the biometric parameters of the plant. In Darmon variety of lentils, the height of the stem was 51.1-58.8 cm in autumn, 43.7-52.2 cm in spring, the leaf area was 23.2-35.8 thousand m3 in autumn and 22.2-33.7 thousand m3 in spring. As a result of symbiotic activity, the weight of nodules in the autumn was 3.17-4.52 c / ha, in the spring - 2.82-3.98 c / ha, and per thousand grains - 78.9 -81.9 grams in the autumn and 78.5-81.1 grams in the spring. It was found that as the number of seedlings increased, the weight of thousands of grains on the options decreased due to lack and high demand of nutrients. The same pattern was observed in the location of the first pod in both periods, but in the spring due to external factors the location of the lower pod was slightly higher, the yield in the autumn was 24.3-27.4 c / ha, and in the spring - 17.1-20.3 c / ha, and the best result was found to be obtained when seeds were sown on 3 million pieces/ha.
