Other claims from this paper (8)
- Intervention effect Nitrate alone or with NH4-N increased leaf fresh weight, leaf dry weight and leaf area of onion compared with NH4-N as the sole N source.
- Intervention effect Nitrate alone or with NH4-N increased root fresh and dry weight and bulb dry weight of onion compared with NH4-N as the sole N source.
- Intervention effect Bulb fresh weight of onion was highest with an NH4-N to NO3-N ratio between 1:3 and 3:1.
- Association Maximum leaf fresh weight was not necessary for maximum bulb fresh weight of onion under different N-form ratios.
- Intervention effect Precocious bulbing of onion occurred when NH4-N was the sole N source.
- Association High bulbing ratios early in plant development were not correlated with final bulb fresh weight of onion.
- Intervention effect Nitrogen form influenced water uptake of onion.
- Intervention effect Nitrogen form influenced onion pungency, measured as enzymatically developed pyruvate concentration.
