Other claims from this paper (7)
- Intervention effect Young rice plants grew better with ammonium than with nitrate as N source
- Intervention effect Nitrate was less readily assimilated than ammonium once complete foliage cover was obtained
- Intervention effect Growth rate was the same for both forms of N, controlled mainly by environment and nutrient supply
- Intervention effect Restoring N supply to N-depleted rice produced an earlier renewal of growth with ammonium
- Intervention effect After restoring N supply, rice yielded more on a given date with ammonium than with nitrate
- Intervention effect Rice eventually regained the same rate of linear growth after N restoration with either form of N
- Intervention effect Plants given nitrate contained more carboxylates than plants given ammonium, irrespective of plant age or temporary N shortage
