Other claims from this paper (5)
- Intervention effect At high N (2.5 mM) in hydroponic culture, NH4+ instead of NO3- decreased dry matter production and leaf area by about 35%.
- Intervention effect Replacing NO3- by NH4+ as the N source increased water use efficiency.
- Intervention effect NH4+ did not affect the nutrient content of the plant tissues of wild swiss chard.
- Intervention effect Replacing NO3- by NH4+ decreased the NO3- concentration in consumable leaves.
- Intervention effect At low N (0.5 mM) the difference between NO3- and NH4+ was not significant.
