Table 2.

Analysis of variance p-values (three-way ANOVA) testing the effects of year, treatment, and variety on leaf area index (LAI), cumulative actual evapotranspiration (ETa, mm), grain yield (GY, kg·ha⁻¹), cumulative actual evapotranspiration during vegetative stages (ETa VEG, mm), cumulative actual evapotranspiration during grain filling (ETa GF, mm), and water productivity (WP, kg·m⁻³). Na: Not available. For the cumulative actual evapotranspiration, data from all three blocks were used for calculation and all block effects were removed from the ANOVA.
