Title
Effect of mineral nitrogen on spring growth and nitrogen fixation of white clover lines
H. B. Berthelsen; James D. Ford; Jessica Evans 1994
Other claims from this paper (10)
- Intervention effect Applied nitrogen reduced fixation more than clover yield or sward content.
- Observation No nitrogen-treatment by breeding-line interactions were found.
- Intervention effect Applied nitrogen significantly decreased fixation.
- Intervention effect Applied nitrogen increased clover percent nitrogen.
- Intervention effect Applied nitrogen increased grass percent nitrogen.
- Observation Dates and breeding lines differed significantly for most measured characters.
- Association Nitrogen treatment interacted significantly with date for fixation.
- Association Cultivar interacted significantly with date for clover proportion in the sward.
- Association Cultivar interacted significantly with date for nitrogen fixation efficiency.
- Recommendation The authors caution that white clover cultivars may not reliably maintain high fixation or cease fixation up to 200 kg N/ha.
