Summary

A trial was conducted to evaluate chickpea response to various preemergence herbicides at Hettinger, ND in 2023.  Chickpea was seeded on May 3, 2023 using a no-till drill at a depth of 3 inches at a seeding rate of 174,000 seed per acre. Preemergence herbicide treatments were applied immediately after seeding.  Chickpea emerged on May 19.  No visual injury to chickpea was observed.  No differences in chickpea stand count was found for the different herbicide treatments (Table 1). Most treatments resulted in chickpea height that was equal to or greater than in the untreated control.  All treatments resulted in yield that was higher than yield of the untreated control.  Yield in the untreated control was reduced by weed competition.
