e0“Significant increases in rapeseed yields, compared to the control treatment (without Cu), were obtained in treatments fertilised to the soil with doses of 8 and 12 kg Cu⋅ha -1 and in the treatment with foliar spraying”
e2“there was a tendency for the copper content in seeds to increase favourably, especially in the case of foliar application and of the higher copper doses applied to the soil”
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 Soil copper fertilisation at 8 and 12 kg Cu per ha significantly increased rapeseed yield relative to the no-copper control.
- Intervention effect Foliar copper spraying at 250 g Cu per ha significantly increased rapeseed yield relative to the no-copper control.
- 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.
