Other claims from this paper (12)
- Intervention effect Winter faba bean varieties did not achieve a higher grain yield than the spring faba bean in eastern Austria.
- Intervention effect Winter faba bean varieties did not achieve a higher grain N yield than the spring faba bean in eastern Austria.
- Intervention effect Winter faba bean varieties had a higher grain N concentration than the spring faba bean, except for one variety.
- Observation Winter faba beans were susceptible to frost damage, especially in the harder of the two winters.
- Intervention effect Drought in one year severely impaired grain N yield of faba beans, to a mean of 8.3 g N m−2 against 6.4 g N m−2 for winter wheat.
- Intervention effect Drought in one year severely impaired grain yield of faba beans.
- Observation In the other year, grain N yield of faba beans considerably surpassed that of winter wheat, 21.5 against 8.8 g N m−2.
- Observation Faba beans left higher nitrate residues in the soil than winter wheat, especially in the subsoil.
- Observation Faba beans left higher amounts of N in above-ground residues than winter wheat.
- Intervention effect Drought considerably impaired N fixation of faba beans, to a mean of 6.3 g N m−2.
- Observation Under drought, N fixation of autumn-sown and spring-sown faba beans showed no differences.
- Intervention effect Growing winter faba bean varieties in eastern Austria did not give higher grain yield, grain N yield or N fixation than a spring faba bean.
