Influence of dozes of the growth regulator Ekosil on yield and seeds quality of winter turnip rape

Influence of the growth regulator of plants Ekosil on elements of yield structure of winter turnip rape was studied. The growth regulator Ekosil was applied in a dose 0.1 liter per ha in the beginning of a budding formation phase and in a dose 0.1 liter per ha at the end of a full budding phase. This increased quantity of pods per a plant by 4-6 units, weight of 1000 seeds by 0.2-0.4 g, seeds weight per a plant by 0.54-1.1 g, biological productivity of oilseeds by 0.32-0.46 t per ha compared to a control. Increasing of Ekosil dose up to 0.15-0.25 liter per ha in two terms did not raise a biological productivity of oilseeds. The growth regulator Ekosil did not influence on quantity of seeds in a pod. Application of the growth regulator Ekosil in a dose 0.1 liter per ha in the beginning of a budding formation phase and in a dose 0.1 liter per ha at the end of a full budding phase has ensured the maximal biological productivity of the crop - 5.0 t per ha at following elements of yield structure: plants population before harvesting - 61 plants per sq. m, quantity of pods per a plant to harvesting - 110 units, quantity of seeds in a pod - 19.7 units, weight of 1000 seeds - 3.8 g, weight of seeds from a plant - 8.2 g. On the average for three years, the maximal yield of seeds of winter turnip rape (3.0 t per ha) was in the second variant, the increase to the control was 0.3 t per ha, or 11.6%. The winter turnip rape variety Veronika had the greatest increase of a crude protein yield (0.10 t per ha) at Ekosil application in a dose 0.15 liter per ha in the beginning of a budding formation phase and in a dose 0.15 liter per ha in a phase of full budding, and on oil yield (0.12 t per ha) - at a dose 0.1 liter per ha in two terms at the same phases.
