camelina, seeding date, quality traits
Identifying crops that are adapted to dryland environments of the central and northern Great Plains (GP) has been a major challenge. An alternative crop with potential for dryland crop production in the GP is camelina (Camelina sativa L. Crantz). Time of planting is an important management consideration that can affect camelina production. Early planting allows camelina to mature before the onset of hot summer temperatures in the central GP that can affect seed yield. A study was carried out in the spring of 2013 and 2014 to evaluate planting date effects on spring camelina varieties grown under dryland conditions in western Kansas. In this study, three spring varieties (Blaine Creek, Pronghorn, and Shoshone) were planted at three seeding dates (early, mid, and late). Parameters collected included plant height, harvest index, seed yield, and oil and protein content. Our findings indicate that seeding date affected time of flowering and physiological maturity (P < 0.05) but had no effect on oil content. Year × camelina variety interaction had a significant effect on seed yield. Similarly, protein content differed among the varieties (Blaine Creek > Pronghorn > Shoshone). Blaine Creek consistently produced the highest yield in both years and had a protein content of 30%.
