Abstrakt: Crop yields are mostly dependent on the climatic conditions and structural indexes where perennial and annual herbs have special value as previous crops. White melilot is an important annual herb that should be introduced into the crop rotations of the Steppe zone. Seed productivity of white melilot depends on a number of factors including the growth conditions and features of the cultivated variety. The best results in the increase of seed productivity of the crop could be achieved by the optimal agrotechnological and chemical measures of weed management herewith the application of herbicides is characterized with the highest efficiency. The three-year study was conducted in the conditions of the Steppe zone of Ukraine on the dark-chestnut soil to determine the best option for chemical weed management in the crops of white melilot. It was determined that the highest seed productivity of the crop with the average seed yield of 840.0 kg/ha and best sowing qualities of the obtained seeds (the energy of sprouting of 81%, seedling rate of 85%, 1000 seeds weight of 2.06 g) were achieved on the variant with application of herbicide Pulsar 40 (active substance imazamox, 40 g/l) in the dose of 1.0 l/ha. Therefore, we recommend the utilization of imazamox-based herbicide for weed management in the crops of white melilot under its cultivation in the conditions of the Steppe zone.
