Other claims from this paper (7)
- Intervention effect Spinach yield was highest at 16.5% soil water content with 170 kg ha−1 nitrogen fertilizer.
- Intervention effect Spinach yield was lowest at 12.5% soil water content with no nitrogen fertilizer.
- Association Spinach oxalate content depended strongly on irrigation and nitrogen fertilization levels.
- Intervention effect Nitrogen fertilization significantly decreased spinach nitrogen use efficiency.
- Intervention effect Increasing nitrogen fertilizer use improved spinach water use efficiency.
- Intervention effect Increasing nitrogen fertilizer use improved profit from spinach production.
- Recommendation The authors recommend 85 kg ha−1 nitrogen fertilizer and 16.5% soil water content for field spinach to optimize quality and earnings.
