Development of dry bean cultivars less dependent on fertilizer, pesticide, water, and other inputs is essential for reducing their adverse impact on environment and production cost and for sustainable production systems.  The objectives of this research were to (1) compare seed yield of 16 cultivars in on-farm high- and low-input organic and conventional production systems, and (2) identify high yielding cultivars within and across production systems. Three landraces or selection thereof and 13 cultivars of great northern, pinto, and red market classes released between 1932 and 1998 were evaluated for seed yield in on-farm high- and low-input organic and conventional production systems in southern Idaho in 2003 and 2004. Mean seed yield were the highest and lowest, respectively, in high- and low-input organic production systems. Red cultivars had slightly higher yield than others. Pinto Bill Z, CO 46348, and Othello and red NW 63 and UI 239 had high mean yield with low range across production systems. ‘Matterhorn’ in high-input conventional, NW 63 in low-input conventional, Bill Z in high-input organic, and ‘Buster’ in low-input organic had the highest yield. Implications of these results for future breeding will be discussed.
