Agricultural drought is a condition that threatens natural ecosystems, water security, and food security. The timely identification of an agricultural event essential to mitigating its effects. However, achieving reliable accurate assessment challenging due the interannual variability precipitation in region. Therefore, objective this study was identify months with during cycle maize crop (Zea mays L.)

ABSTRACT Irrigation scheduling is crucial for ensuring precise water delivery to crops. However, in many sub‐Saharan African irrigation schemes, applied without considering crop needs, resulting low productivity and yields. Solar‐powered systems can automatically meet these needs by utilizing solar radiation, which drives both evapotranspiration panel power production pumping. This study aimed integrate into a solar‐driven system assess the impact of meteorological variables on reference (ET o ) Ghana. A 50‐watt powered 12‐V submersible pump, with flow meter installed outlet pipe hourly volume pumped (VWP) data readings. These were used examine correlations between radiation (R s ET , as well R VWP. Partial correlation analyses relative influences wind speed (U 2 ), humidity (RH) air temperature (T across 10 locations Ghana's agroecological zones. The revealed strong linear ( > 0.9) VWP = 0.8). was sufficient crop‐water demand year‐round. Solar consistently primary factor influencing
