INFLUENCE OF STRUCTURAL INDICES ON SEED YIELD OF WHITE MELILOT OF PIVDENNY VARIETY DEPENDING ON APPLICATION OF HERBICIDES TREFLAN 480 AND PULSAR 40 IN CONDITIONS OF THE SOUTH STEPPE OF UKRAINE

Abstract
Conducted researches determined the influence of structural indices on the seed yield of white melilot of Pivdenny variety depending on the studied herbicides Treflan 480 and Pulsar 40 at different application rates. The highest yield of seeds (840.0 kg / ha), as well as the best structural indices of white melilot, were obtained by using the herbicide Pulsar 40 at the rate of 1.0 L / ha where the optimal plant standing density of white melilot provided the appropriate development of the crop plants. Under the conditions of Southern Steppe of Ukraine, the seed yield of white melilot of Pivdenny variety directly depended on the crop’s plant standing density, the number of bunches per plant, the number of seeds per bunch, 1000 seeds weight. The application of herbicides contributed to the better formation of a large number of generative organs of the studied crop, which subsequently influenced the seed productivity of white melilot of Pivdenny variety that is proved by the simulated indices of structural elements.
