*2.6. Statistical Analysis*

Statistical analysis was conducted using analysis of variance procedures using CoStat version 6.451 [46]. The difference between means was compared using a least significant difference test (LSD) at the 5% level (*p* ≤ 0.05).

#### **3. Results and Discussion**

#### *3.1. Evapotranspiration and Applied Irrigation*

There was variation in the weather parameters of the WS and SS (Figure 1). Air temperature, solar radiation intensity, and wind speed were higher in the SS than the WS. However, in the WS, the relative humidity was higher than in the SS. This caused a 73% increase in the seasonal reference evapotranspiration (ETo) in the SS, compared with the WS (Figure 2). As irrigation scheduling was based on ETc, more water was consumed in the SS than the WS (Figure 4).
