Evaluation location: Colorado, United States
Accessions were planted on May 24, 2002 at the Southwestern Colorado Research Center, with a Monosem Planter at 3.75-in seed spacing and 30-in. row spacing. Each accession was planted in a 60-ft single row with no replication. The soil at the test site is a Wetherill loam (fine silty, mixed, superactive, mesic Aridic Haplustalfs). The plot area was irrigated with a line-source sprinkler system similar to the one described by Hanks et al. (1976)*. The amount of irrigation water decreased with the distance away from the sprinkler line. For practical purposes, we only distinguished two irrigation levels, wet and dry. Total precipitation from May to August was 1.01 in. compared to a 30-year average of 5.13 in. September rainfall was above normal but came late for most chickpea entries.
