Other claims from this paper (10)
- Intervention effect Increasing nitrogen fertilizer rate increased barley grain yield by 45%.
- Intervention effect Increasing nitrogen fertilizer rate increased barley shoot dry weight by 11%.
- Intervention effect Increasing nitrogen fertilizer rate increased barley root dry weight by 36%.
- Intervention effect Full organic compost produced higher barley grain yield than either full or half mineral nitrogen fertilizer.
- Intervention effect Full organic compost gave shoot and root dry matter yield near the half-mineral-nitrogen treatment but below the full treatment.
- Intervention effect Combined organic and mineral nitrogen did not differ significantly from half-rate mineral nitrogen.
- Intervention effect Full fertilizer rate yielded higher nitrogen derived from fertilizer than half rate.
- Intervention effect Grain, shoot, and root nitrogen derived from fertilizer under combined treatment approached half-rate mineral nitrogen.
- Observation More barley nitrogen was derived from organic compost, with grain exceeding shoots and roots.
- Intervention effect Half-dose nitrogen plus compost gave efficient use by grain and roots, near half-rate mineral nitrogen alone.
