4.1. Site Characteristics

A field experiment was carried out over two periods of time; from 2016 to 2018, and from 2017 to 2019 at the Agricultural Research Station, Crop Science Department, Alexandria University, located at 31.22° N, 29.94° E. The experimental location was characterized by its Mediterranean climate, average monthly temperature (°C), and humidity (%) for the two summer seasons (2018 and 2019), where the terminal maize crop was planted, are presented in Figure 4 and Figure 5, respectively. The physical and chemical characteristics of the experimental soil are presented in Table 6.
