Other claims from this paper (13)
- Intervention effect Field horsetail showed no response to N supply in the first growth period.
- Intervention effect Only dry weight of new belowground production responded to increased light.
- Observation Rhizomes were produced during the latter part of the 52-day period.
- Intervention effect Total new tissue production was reduced only at the two lowest N supply rates, 6 and 18 kg N ha –1.
- Intervention effect The ratio of shoot to belowground organ dry weight increased only as N supply increased.
- Intervention effect Shoot height response to increased N supply was small.
- Observation Field horsetail can be considered tolerant of low levels of N.
- Observation Field horsetail is expected to be overtopped by fast-growing species when competing for increased N supplies.
- Intervention effect An increase in N supply increased the reduction of dry weight of planted rhizomes.
- Intervention effect A reduction in light increased the reduction of dry weight of planted rhizomes.
- Intervention effect Tuber production was favored by low N supply.
- Intervention effect Tuber production was favored by high light intensities.
- Observation Field horsetail is not likely to be competitive in a dense crop stand.
