stress (Doorenbos and Kassam, 1979). The fruit and seed yields of
squash were significantly affected in a linear relationship (r2 ≥0.91)
by either deficit or surplus irrigation quantities under both irrigation
methods; and the yield response factor was 0.77 (Amer, 2011).
Ertek et al. (2004) found a significant positive linear relationship
among irrigation water, plant water consumption, fruit traits, and
yield.
