Formation dynamics of biomass of lentil crops depending on the plant density in the steppe zone of Kazakhstan

The right planting density and the optimal number of seeds introduced during sowing play a crucial role in ensuring the efficient production of lentils. This factor significantly affects the process of culture rooting, the ability of plants to absorb solar radiation, the development of vegetation cover, as well as the level of infection with harmful insects, pests, and diseases. The purpose of this study was to investigate the influence of seeding rates on the formation of plant biomass and yield at different sowing dates. The object of the study was an early-ripening variety of lentils, i.e., Shyraily. One-Way ANOVA was used to study the impact of sowing dates (May ۱۰, May ۲۰, May ۳۰) and seeding rates (۱.۰ million, ۱.۳ million, ۱.۶ million germinating seeds per ha) of lentils on plant biomass and yield. According to the results of two-year studies, the maximum yield of lentil grain was formed when sowing on May ۳۰ and at a seeding rate of ۱.۳ million germinating seeds per ha – ۱۱.۵ c/ha. It was found that the greater the density of the plants, the higher the yield of lentil grain.
