Fig. 1. The relative dry matter yield of melon as affected by irrigation and salinity treatments (a) with piecewise linear models fit to the irrigation response data for each salinity treatment and (b) with piecewise linear models fit to the irrigation response data for the lowest salinity treatment and irrigation response data for each salinity treatment above the critical irrigation level (the intercept of the two line segments).
