GERMINATION AND DENSITY OF SUNFLOWER HYBRID PLANTS AT PRESOWING SEED TREATMENT
Journal Title: Подільський вісник : сільське господарство, техніка, економіка - Year 2018, Vol 1, Issue 28
Abstract
The results of a four-year study on the application of the "Vermimag" and "Vermiyodis" growth regulators on pre-sowing seed treatment, density of sunflower seeds of hybrids NK Briio and NK Rocky are presented. It was found that the highest (83.7 % and 85,7 %) results we got with seeds of hybrids NK Briio and NK Rocky treated before sowing with the preparation " Vermiyodis " (5 l/t), which, respectively , by 6.1 and 6,9 % more compared to controls. Pre-sowing seed dressing of hybrid seeds of NK Berio and NK Rocky growth regulators "Vermimag" (6-7 l/t) and "Vermiyodis" (4-5 l/t) also contributed to maintaining the plant density during the growing season and ensured the plant density before harvesting 97.5 - 99.7 %, which is 2.8 - 5.0 % more than control. The best indices were obtained with the seed of the NK Rocky hybrid with the drug "Vermiyodis" (5 l/t) - the field similarity was 85,7 % (more than 6,9 % before the control), 59286 pieces/ha remained during the period of harvesting of the crop plants, or 98,8 %, which is more than the control for 5,3 %.
