Other claims from this paper (17)
- Intervention effect Maize ETa, LAI and biomass production were significantly affected by the irrigation regimes.
- Intervention effect Maize grain yield and HI were significantly affected by the irrigation regimes.
- Observation Maize yields in 2009 varied from 9.05 Mg ha-1 under the rainfed treatment to 15.5 Mg ha-1 under FIT.
- Observation Maize yields in 2010 varied from 11.7 to 15.5 Mg ha-1 across the respective treatments.
- Observation Harvest index ranged from 0.49 under rainfed to 0.57 under FIT, with an all-treatment average of 0.54.
- Observation Maize ETa ranged from 481 mm under rainfed to 620 mm under FIT in 2009.
- Observation Maize ETa ranged from 579 mm to 634 mm under the same treatments in 2010.
- Association The yield versus ETa relationship had R2 of 0.94 in 2009.
- Association The yield versus ETa relationship had R2 of 0.97 in 2010.
- Mechanism Yield-irrigation and yield-ETa relationships varied between the two years, attributed to weather variability.
- Recommendation Accounting for weather variability in the slopes of crop yield production functions is important.
- Observation Maize produced 1.2 Mg ha-1 of grain yield per 25.4 mm of ETa beyond 280 mm in 2009.
- Observation Maize produced 1.7 Mg ha-1 of grain yield per 25.4 mm of ETa beyond 403 mm in 2010.
- Observation Yield response factor averaged 1.65 in 2009.
- Observation Yield response factor averaged 2.85 in 2010.
- Observation Yield response factor averaged 1.82 over the two years.
- Intervention effect Grain yield did not differ significantly between 75% FIT and 100% FIT.
