• Influence of Row Spacing on Crested Wheatgrass Seed Production

      McGinnies, W. J. (Society for Range Management, 1971-09-01)
      Crested wheatgrass was planted in rows spaced 6, 12, 18, and 24 inches apart. During 2 years of above-average precipitation, plants in all row spacings produced enough seed to justify harvesting, but during 2 years of average precipitation, only the plants in the 18-and 24-inch spacings produced sufficient seed. In a dry year, plants in none of the spacings produced enough seed to harvest. When a seeded field is to be used for forage in dry years and seed production in wet years, an 18-inch row spacing is suggested for northern Colorado.
