2.The effect of foliar fertilisation with Ekolist S on yield and quality of motherwort herb (Leonurus cardiaca L.)   - Anna Kiełtyka-Dadasiewicz, Stanisław Berbeć

Abstract.
In 3-year fi eld experiment on loamy soil effect of foliar fertilization with Ekolist S (containing macro- and microelements) on growth and yielding of motherwort was studied.
Ekolist S was applied in form of 1% solution in the fi rst year of vegetation twice: at the end of May and in middle of June, while in the second year – three times: at rosette stage (April/May),
3 week later, and 2 weeks after fi rst harvest. Ekolist S, irrespective of plant age (in fi rst and second year of vegetation) had benefi cial infl uence on plant growth and brought about higher yields of herb (on average by 85% in the fi rst year and by 42% in the
second one).
  The effect of Ekolist S on quality of herb was not univocal. In the fi rst year of vegetation it resulted in advantageous decrease of stalk contribution in herb but acted conversely on the second year during the fi rst harvest. Effect of Ekolist S on fl avonoids content was not clear: noticeable increasing tendency in the fi rst year of vegetation and decreasing in the second (regards fi rst harvest) indicates an interrelation with contribution of stalk in herb (the higher contribution the lower fl avonoids content).  Theoretical yields of fl avonoids (resultant of herb yield and fl avonoids content) every year were markedly higher in object, where Ekolist S
was applied.
