The scientists used weather data to predict wheat yield in Kanpur, Uttar Pradesh. They looked at temperature, humidity, and rainfall over 16 weeks of crop growth. By using a special math model, they could forecast how much wheat would be produced. They tested the model on data from 1971 to 2006 and found it worked well. The results were checked against actual yields from 2007 to 2010, and the predictions were pretty accurate. This method could help farmers plan better for their wheat crops in the future.
