Fig 2. The effects of combining different irrigation rates with different plant densities on measured agronomic parameters in two growing seasons.

Bars with different letters are significantly different from each another at P ≤ 0.05. Vertical bars indicate standard error (n = 3). D₁, D₂, D₃, D₄, and D₅ indicate plant densities of 150, 250, 350, 450, and 550 seeds m^-2, respectively.
