- Observation DOR population density declined over the season, especially at overwintering and pod development.
- Intervention effect Nutrient deficiency lowered DOR nutrient concentration.
- Intervention effect Nutrient deficiency limited DOR dry matter production.
- Intervention effect Nutrient deficiency limited DOR nutrient uptake.
- Intervention effect Nutrient deficiency exacerbated DOR density reduction.
- Observation Poor individual growth and reduced density together decreased DOR seed yield.
- Intervention effect Nitrogen deficiency reduced average seed yield by 61%.
- Intervention effect Phosphorus deficiency reduced average seed yield by 38.3%.
- Intervention effect Potassium deficiency reduced average seed yield by 14.4%.
- Observation Negative effects on DOR performance ranked N deficiency above P and K deficiency.
- Intervention effect Nitrogen deficiency caused substantial plant death and low harvested density.
- Intervention effect Phosphorus deficiency significantly reduced initial density.
- Intervention effect Phosphorus deficiency limited plant growth.
- Intervention effect Phosphorus deficiency exacerbated density reduction.
