Other claims from this paper (9)
- Intervention effect In an incubation study, FYM application marginally improved the DTPA-Fe status of soil over control.
- Intervention effect Iron sulfate at 14 mg Fe/kg with FYM released as much Fe as 27 mg Fe/kg as iron sulfate alone in the incubation study.
- Intervention effect Higher amounts of Fe were released under water saturation than under drier soil moisture regimes.
- Observation The effect of incubation period on Fe release was pronounced only under water saturation.
- Intervention effect Foliar application of Fe was the most effective and economical way to correct Fe deficiency in aerobic rice, followed by soil application of FeSO4.7H2O with FYM and soil application of FeSO4.7H2O alone.
- Association Among the rice cultivars, CT 6510-24-1-2 and IR 71525-19-1-1 performed better under aerobic condition than IR 36 and IR 64.
- Mechanism The differential response of rice cultivars to applied Fe was not related to Fe nutrition but was apparently related to their inherent ability to grow under water stress.
- Method / resource FeII content in rice plants was a better index of Fe-nutrition status than total plant Fe and chemically extractable soil Fe.
- Recommendation A plant FeII concentration of at least 37 mg kg-1 dry weight at 60 days after sowing appeared adequate for direct seeded rice under upland aerobic condition.
