Biomass partitioning of maize was evaluated under two deficit irrigation strategies. The deficit strategies were fixed interval-variable depth (M1) and vice versa (M2). Total biomass production was on average around 25% higher for M1. Maize plants were more sensitive to water stress under M2. Compared to M2, M1 was a better deficit irrigation management strategy.
