Title
EFFECT OF FOLIAR AND SOIL APPLICATION OF COPPER ON THE LEVEL AND QUALITY OF WINTER RAPESEED YIELDS
U. Sienkiewicz-Cholewa Journal of Elementology 2008
Other claims from this paper (5)
- Intervention effect Foliar copper spraying at 250 g Cu per ha significantly increased rapeseed yield relative to the no-copper control.
- Association Copper application tended to increase copper content in rapeseed seeds, especially with foliar application.
- Intervention effect Copper fertilisation increased seed oil content in some cases, by several percent relative to untreated plots.
- Observation Plants from treatments without copper fertilisation had insufficient copper content.
- Recommendation Fertilisation of rapeseed with copper appears crucial given the copper deficit in Polish soils.
