Field trials are experiments conducted in real-world settings to test the effectiveness and performance of new products, techniques, or practices. These trials often involve agricultural crops, where researchers assess how different variables, such as soil type or weather conditions, affect growth and yield. The goal is to gather data that can inform future decisions and improvements. In addition to agriculture, field trials can also be used in other fields, such as medicine and technology. For example, clinical trials test new drugs in diverse populations to evaluate their safety and efficacy. Overall, field trials provide valuable insights that help refine innovations before they are widely adopted.
