Abstract:
WestBred 881 durum commands a premium price due to its superior quality, but it produces a lower yield than other commonly grown cultivars. This study was initiated to improve our understanding of how to grow WestBred 881. Two dumm cultivars (WestBred 881 and Aldura) were planted at five seeding rates (30, 60, 120, 180, and 240 lbs seed /A) and five row spacings (3, 6, 12, 18 an 24 inches) at the Marana Agricultural Center. The optimum seeding rate was 180 lbs /A for WestBred 881 and 120 lb /A for Aldura. An increase in seeding rate resulted in decreased kernel weight and number and increased head number. At row spacings of 3, 6 and 12 inches, grain yield of WestBred 881 was 6120, 6300, and 6060 lbs /A and grain yield of Aldura was 6350, 6770, and 7190 lb /A, respectively. WestBred 881 has larger kernels than Aldura but fewer kernels per head and heads per unit area. The yield advantage of WestBred 881 relative to Aldura at higher seeding rates was due to in kernels per head. At the closer row spacings, the advantage was due to kernel weight, kernels per head and heads per unit area.
