Other claims from this paper (13)
- Intervention effect Waterlogging for 48 or 72 hours at knee-high and tasselling stages retarded growth in all varieties except Ganga-2.
- Intervention effect Submergence for 72 hours reduced K uptake in all corn varieties.
- Intervention effect Submergence for 72 hours increased P uptake in all corn varieties.
- Intervention effect Calcium and Mg uptake were unaffected by submergence.
- Observation Corn grain yield was ordered Jaunpur, Kisan, Vijay, Ganga-7, then Ganga-2 from lowest to highest.
- Intervention effect Flooding at knee-high stage was more harmful than flooding at tasseling stage.
- Observation The critical knee-high waterlogging limit for Ganga‐2 was 72 hours.
- Observation The critical knee-high waterlogging limit for other varieties was 48 hours.
- Intervention effect Seventy-two hours of flooding at tasselling did not reduce Ganga-2 yield.
- Intervention effect Seventy-two hours of flooding significantly decreased yield in the other varieties.
- Observation Ganga-2 had maximum gas spaces under waterlogging.
- Observation Ganga-2 developed an extensive adventitious root system at the water surface under waterlogging.
- Mechanism The authors attribute Ganga-2 waterlogging tolerance to gas spaces and adventitious roots.
