Other claims from this paper (12)
- Intervention effect Increased plant water stress reduced the duration of bud and flower production, stem length and potential seed yield in red clover.
- Intervention effect Increased plant water stress reduced red clover seed yield.
- Intervention effect Water applied soon after haying increased above-ground phytomass in red clover.
- Intervention effect Water applied soon after haying increased red clover seed yield less than watering at peak flowering.
- Association A root and crown rot disease complex reduced second-year red clover seed yield.
- Association Root rot index increased with increasing plant water stress in red clover.
- Intervention effect Supplemental water applications reduced root rot severity in red clover.
- Mechanism The reduction in red clover seed yield under increased water stress was primarily caused by a decrease in floral fertility.
- Mechanism Reductions in flower number per unit area may also contribute to the seed yield reduction under water stress, less conclusively.
- Observation One irrigation filling the active soil profile during peak flowering maintained red clover seed production.
- Observation One irrigation filling the active soil profile during peak flowering gave high water-use efficiency in red clover.
- Intervention effect Supplemental irrigation greatly reduced yield losses to root disease in the second year of red clover seed production compared with non-irrigated clover.
