Field trials are experiments conducted in real-world settings to test the performance of new products, techniques, or practices. These trials often involve agricultural crops, where researchers assess how well a new seed variety or farming method performs under natural conditions. The goal is to gather data on effectiveness, yield, and any potential issues that may arise. In addition to agriculture, field trials can also be used in other fields, such as medicine or 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 improve products and practices before they are widely adopted.
