Abstract

Millet is a type of C₄ grass that grows best in warm, dry climates. Because water is often scarce in these areas, farmers are always looking for ways to grow millet while using less water. This is called improving water use efficiency (WUE). Field experiment was conducted in the 2023 growing season at Maryout research station, Desert Research Center, Egypt to evaluate the effect of design parameters of sprinkler, sowing date on heat stress water use efficiency and Millet crop productivity. The experiment was sown with Millet seeds on two dates. The first was 25 June (S1) and the second was 10 July (S2). Two nozzles’ diameters 3.2 mm and 3.9 mm were compared under three different riser heights 1.0 m, 1.20 m and 1.40 m to study the impact of sprinkler height and nozzle diameter on the two different dates (S1, S2) on biomass of Millet crop. It is recommended to use this schematic model representation of the of the system conception, which represents the behavior of the system. There is a significant response between (Yield), growing degree-days (AGDD), Sprinkler height (L), water quantity (Q) and Sprinkler Nozzle diameter (N) with R2 more than 0.90.
