Other claims from this paper (8)
- Observation Spring nitrogen raised strawberry yield to 43.1 t ha‐1 versus 26.0 t ha‐1 without spring nitrogen.
- Intervention effect Autumn nitrogen did not markedly affect yield.
- Intervention effect Autumn nitrogen shifted production peaks.
- Intervention effect Without autumn nitrogen the production peak was delayed.
- Intervention effect The highest yields came from 36.5 kg N ha‐1 in spring and autumn split applications.
- Intervention effect Potassium applications did not greatly affect yield.
- Recommendation The authors recommend small regular nitrogen applications from midwinter for optimum yield.
- Recommendation The authors recommend about 40 ppm Bray II extractable soil potassium for better fruit size.
