Other claims from this paper (19)
- Intervention effect Both Wright and Hutton soybean cultivars showed a significant response to applied Zn
- Intervention effect Hutton showed the greatest response to applied Zn, compared with Wright
- Observation Wright had seed yields as great as or greater than those of Hutton
- Association Yield of both soybean cultivars was significantly correlated with leaf Zn concentration and with the P/Zn ratio
- Association The highest yields of both cultivars were associated with leaf Zn concentrations of approximately 26 μg/g
- Association The highest yields of both cultivars were associated with a P/Zn ratio of 115
- Intervention effect Copper fertilization increased Cu concentration in plant tissue by 38% to 58%
- Intervention effect Copper fertilization did not influence seed yields
- Intervention effect Seed yield and Zn absorption of both cultivars were reduced by increased pH
- Intervention effect Seed yield decreased at a faster rate when Zn was not applied than when plants received Zn fertilizer
- Intervention effect Copper concentrations in plant tissue were not affected by increased soil pH
- Association Zinc concentration of leaf tissue was affected by a P-Zn interaction
- Observation Wright had much greater concentrations of leaf Zn, Fe and Cu than Hutton
- Observation Wright had much greater concentrations of several other nutrients than Hutton
- Mechanism The greater ability of Wright to absorb these elements may account for the difference in tolerance to P induced growth disorders between the cultivars
- Association Within each pH treatment, Zn absorption was highly correlated with extractable soil Zn
- Method / resource When soil pH was not taken into account, neither DTPA nor Mehlich No. 1 extractable soil Zn adequately predicted Zn absorption
- Method / resource Prediction equations accounted for 80% to 95% of the variation in leaf Zn concentration
- Method / resource Multiple linear regression prediction equations with extractable soil Zn and pH gave better results than DTPA or Mehlich No. 1 extractable soil Zn
