Other claims from this paper (16)
- Intervention effect Spring wheat responded only slightly to Ureaform.
- Intervention effect Urea and ammonium nitrate limestone effects did not differ significantly.
- Intervention effect Fertilizer placement tended to increase dry matter.
- Intervention effect Fertilizer placement tended to increase nitrogen content.
- Observation Placement effects were more significant without irrigation.
- Intervention effect Irrigation markedly increased total nitrogen in aerial plant parts.
- Observation Later irrigation associated nitrogen gain reflected higher dry matter yields.
- Observation Surface-dressed fertilizer nitrogen recovery in grain was about 30%.
- Intervention effect Irrigation increased grain nitrogen recovery to 54%.
- Intervention effect Placement increased grain nitrogen recovery to 42%.
- Observation Combined placement and irrigation gave 61% grain recovery.
- Observation Aerial nitrogen recovery averaged 36% for surface dressing.
- Observation Aerial nitrogen recovery averaged 60% for placed fertilizer.
- Intervention effect Irrigation raised aerial recovery for surface dressing to 76%.
- Intervention effect Irrigation raised aerial recovery for placed fertilizer to 96%.
- Recommendation The authors recommend both irrigation and fertilizer placement.
