Abstract
A lysimeters experiment was designed to study how to manage irrigation scheduling using different empirical equations compared to traditional irrigation method. Design of experiment was random block with three replicates. The experiment was repeated in two successive seasons (2016 and 2017) using maize crop. Four irrigation treatments were used as T1for traditional, T2 by Belany - Criddle equation, T3 by Radiation equation and T4 by penman equation. All irrigation treatments were inserted by 70% of soil water depletion. The results showed that T3 had the highest values of water productivity (0.89 kg/m3) and productivity of irrigation (0.63 kg/m3) as an overall average of the two seasons. Data revealed also that T1 had the highest overall mean values applied water fed) revealed that the highest overall mean values for water applied was recorded under T1 (3862.n and water consumptive use (3862.47 m3/fed &2826.02 m3/fed). The results indicated that the highest values for grain yield was recorded by irrigation treatment T3 with values of 2013.90 and 1925.53 kg/fed as well as 16.33 and 18.37cm for ear length in the first and second season, respectively. Also, 100 grain weight and plant height had the highest values by treatment T3 as compared to treatment T1, T2 and T4. Under the condition of this study recommends that, the farmers under the experimental area who cultivate maize crop should irrigate every 11 days to maximize the productivity for crop and both of water productivity and productivity of irrigation water.
