Other claims from this paper (11)
- Observation Mean achenes yield over all years ranged from 3.9 t ha-1 in the control to 4.34 t ha-1 in N 60.
- Observation Achenes yield over all treatments ranged from 3.04 in 2008 to 4.91 t ha-1 in 2010.
- Recommendation Sunflower can be produced with N application up to 60 kg N ha-1 on highly productive soils in the Czech Republic.
- Intervention effect Increasing N application above 60 kg N ha-1 can decrease achenes yield.
- Intervention effect Application of B gave slightly higher achenes yield than the treatment with the same N level without micronutrients.
- Intervention effect Application of Zn gave slightly higher achenes yield than the treatment with the same N level without micronutrients.
- Intervention effect Addition of Mo gave slightly lower achenes yield than the treatment with the same N level without micronutrients.
- Association Achenes and biomass yield were primarily affected by weather conditions in particular years.
- Intervention effect Fertilizer treatments did not significantly affect weight of achenes per head, weight of thousand achenes or number of achenes per head.
- Intervention effect Fertilizer treatments did not significantly affect number of heads per ha or number of achenes per ha.
- Association A significant effect of year was recorded on these yield-component parameters, showing a major effect of weather conditions.
