The study tested using satellite data to figure out how much water wheat needs for optimal growth and crop yield. They compared two methods: one based on the satellite's measurements and another using fixed calculations. They found that during a usual season, both methods worked similarly. However, in a season with unusual weather patterns, like late planting and changes in fertilizer application, the satellite method performed better in predicting water needs for the wheat crop. This means using satellite data can help farmers use water more efficiently for irrigation without impacting crop yield significantly.
