Other claims from this paper (14)
- Intervention effect Higher population density significantly increased spring maize grain yield.
- Intervention effect Higher population density had the opposite yield trend in the Kharif season.
- Intervention effect Defoliation at the 10th fully open leaf stage yielded more grain than defoliation 12 days after silking.
- Intervention effect Defoliation 12 days after silking yielded more grain than defoliation at the 16th fully open leaf stage.
- Intervention effect Greater defoliation at the 16th leaf stage reduced maize grain yield.
- Intervention effect Greater defoliation 12 days after silking reduced maize grain yield.
- Intervention effect Fifty percent defoliation at the 10th leaf stage increased Kharif maize grain yield.
- Intervention effect Increasing population density lowered grain protein percentage.
- Observation Grain protein content was higher in spring than Kharif.
- Observation Leaf protein declined as maize approached maturity, especially with greater defoliation.
- Intervention effect Increasing defoliation significantly lowered sucrose.
- Intervention effect Increasing defoliation significantly lowered reducing sugars.
- Mechanism The sucrose reduction was large enough to account for the total sugar percentage reduction.
- Observation The sugar-to-protein ratio followed a similar declining trend under greater defoliation.
