A 2-year field experiment was conducted at the Kimberly Research & Extension Center in Kimberly, ID in 2016 and 2017. The purpose of the trial was to determine the effect of seeding rate and herbicides on weed control and narrow-row pinto bean. There were five seeding rates in 19-cm (narrow) rows: 25, 31, 37, 43, and 49 seeds m-2. These seeding rates were compared to a standard seeding rate of 25 seeds m-2 in 56-cm (wide) rows, which is the common grower practice in southern Idaho. There were also five weed control treatments included in the study. Weed control was increased with sequential herbicide applications compared to a preemergent application used alone. In 2016, the hand-weeded control produced the highest yield. In 2017, the yield was higher at 37 and 49 seeds m-2 than at 25 seeds m-2 in the wide or narrow rows.
