2.1. Irrigation systems (IS)
Drip and sprinkler irrigation systems were used in the experimental farm and designed as follows:
(a) The drip irrigation system (DIS) was divided into three treatments, each treatment has one valve to on and off and one
pressure gauge to control the operating pressure. In addition, each treatment has three pairs of laterals, with one drip lateral
per corn row and drippers with 2.5 l h−1 flow rate, 30 cm apart.
The laterals were spaced at 50 cm with 16 mm diameter.
