Planting methods affect emergence, flowering and yield of spring oilseed crops in the U.S. central High Plains Academic Article uri icon


  • 2015 Elsevier B.V. Alternative types of planting methods can alter seed placement, and seedling growing conditions. These factors can affect establishment and seed yield of spring oilseed crops, evaluated in six growing environments of the U.S. central High Plains. Seeding with a hoe drill (HD) resulted in the best emergence and stand ratings, and earlier flowering. Emergence and stand ratings for seeding with a no-till drill (NT) were better than ratings for broadcast seeding (BC). Canola (Brassica napus L.) had better stand rating and earlier flowering than Indian mustard (Brassica juncea (L.) Czernj. & Cosson) and Camelina (Camelina sativa (L.) Crantz), which were similar. Oilseed yield was limited by available water or heat stress at all experimental sites. At Colby, with good growing conditions in 2005, canola provided greatest yield (2180kgha-1). Relative productivity of the oilseed species shifted from canola to Camelina with warmer and drier growing conditions. Adapting spring oilseed germplasm to the U.S. central High Plains can focus on cold tolerance for emergence, intensive water extraction to avoid water stress, heat tolerance during flowering and increased harvest index and oil content.
