Other claims from this paper (7)
- Intervention effect A coulter used in fall or spring reduced winter wheat seed yield, indicating crop damage.
- Intervention effect Urea applied at planting gave seed yields relative to spring-applied ammonium nitrate.
- Intervention effect Late fall UAN gave lower winter wheat yields than the same product applied in spring.
- Observation Winter wheat protein levels were generally lower than the 115 g kg -1 marketing target and varied among site-years.
- Intervention effect Late fall surface banded UAN was inferior to other products and timings in both studies.
- Intervention effect Seed yield and protein content of winter wheat were similar for all forms of urea placed at seeding and to spring broadcast ammonium nitrate.
- Intervention effect Protected N sources did not increase nitrogen use efficiency under the low fall and spring moisture of Study 2.
