Other claims from this paper (19)
- Observation Soybean shoot dry matter varied from 17 to 104 g plant−1.
- Observation Soybean shoot δ15N ranged from −1.11 to +5.51‰.
- Observation N derived from fixation ranged from 21 to 96%.
- Mechanism Some soybean genotypes had high δ15N and low fixation fraction due to soil N uptake inhibiting fixation.
- Observation PAN373 contributed the most symbiotic N, 298, 242 and 217 kg N ha−1 in Parys fields 3, 2 and 4.
- Observation LS6164 fixed 271 and 245 kg N ha−1 at Endcot and Devon.
- Observation LS6150 fixed 290 kg N ha−1 at Parys field 1.
- Observation Soybean shoot carbon concentration varied from 44 to 50%.
- Observation Soybean shoot carbon amount ranged from 8 to 48 g C plant−1.
- Observation Soybean shoot δ13C ranged from −27.3‰ to −21.1‰.
- Observation PAN1453 had elevated δ13C of −21.1‰ and inferred greater water-use efficiency.
- Observation PAN737 had elevated δ13C of −23.1‰ and inferred greater water-use efficiency.
- Association N fixed correlated positively with dry matter yield (r = 0.70***).
- Association N fixed correlated positively with C content (r = 0.62***).
- Association N fixed correlated positively with C concentration (r = 0.35*).
- Intervention effect Conventional tillage decreased soybean water-use efficiency.
- Observation North West soybean plants had better growth, higher dry matter yield and enhanced symbiotic performance than those in the other provinces.
- Association Daily maximum temperature correlated positively with dry matter yield (r = 0.39*).
- Association Daily maximum temperature correlated positively with fixed N (r = 0.46**).
