Researchers studied how irrigation affects the microclimate for maize growth in the Crisurilor Plain. They used climate indices to measure aridity and overall climate conditions. Irrigation improved the climate index values, showing a connection between microclimate, water use, yield, and protein content in maize. The Domuţa climate index was more effective than the de Martonne aridity index in quantifying this relationship, as it considers more factors like water, humidity, temperature, and light.
