Influence of applied dozes of the growth regulator Ecosil on yield and quality of oil seeds of winter rapeseed

Influence of the plant growth regulator Ecosil on elements of winter rapе yield structure was studied. The growth regulator Ekosil applied in a doze 0.10 liter per ha in a phase of the budding beginning and in a doze 0.10 liter per ha in a phase of full budding caused an increase of pods quantity per a plant on 7 pods, 1000 seeds weight on 0.3 g, seeds weight from a plant on 1.6 g, biological productivity of seeds on 4.62 quintal per ha in comparison to a control variant. By increasing of Ecosil dozes up to 0.15- 0.25 liter per ha in two dates biological productivity of seeds did not raise. The growth regulator Ecosil did not influence on seeds quantity in a pod. Applying of Ecosil in a doze 0.10 liter per ha in a phase of the budding beginning and in a doze 0.10 liter per ha in a phase of full budding has ensured the maximal biological productivity of crop - 65.25 quintal per ha at following traits: plant population to harvesting - 45 plants per m2; pods quantity per a plant to harvesting - 108 pods; seeds quantity in a pod - 27,2 seeds; 1000 seeds weight - 4,6 g; weight of seeds from a plant - 14,5g. In the average for four years the maximal winter rapеseed seeds yield (47.7 quintal per ha) was received in the second variant, the increase to the control has made 4.0 quintal per ha, or 9.2 %. The greatest increase of crude protein yield (0.9 quintal per ha) winter rapеseed hybrid Petrol F1 provided at Ecosil application in a doze 0.20 liter per ha in the phase of the budding beginning and in a doze 0.20 liter per ha in the phase of full budding, and oil yield (1.8 quintal per ha) - at applying in a doze 0.15 liter per ha in two dates during the same phases.
