The yield contests in the United States are organized by the National Corn Growers Association (NCGA). These contests aim to encourage innovative management practices and the development of new and sustainable products in the field of corn cultivation. The contests include different categories based on tillage type, such as conventional, no-till, or strip-till, which includes ridge-till, minimum-till, and mulch-tillage. There are also categories for irrigated and non-irrigated classes. Category 2 specifically focuses on no-till and includes four subcategories: strip-till, minimum-till, mulch-till, and ridge-till.
