Differences in Seed Yield, Meal and Oil Quality by Winter Canola Variety and Planting Date in Tennessee
Abstract
Canola (Brassica napus L.) is a cool season crop from the mustard (Brassicaceae) family developed in the 1970s, which contains about 40% oil. This research was carried out to determine the differences in yield and qualities of some winter canola varieties during two growing seasons (2014-2015 and 2015-2016) in Ashland City, Tennessee. In this research, randomized complete block design (RCBD) was used with four replicate in the two growing seasons. Seed yield, oil content and protein content were significantly different between the common cultivars when both years were combined. Exp 1302 (3423 kg ha-1) was greatest in terms of seed yield across both years while Einstein (44.32%) and Sumner (380 g kg-1) were the greatest for oil and protein content, respectively. For seed yield, Exp1302, Hekip, Einstein, Hornet, Edimax CL, DK Imistar CL, Claremore and DK Sensei had greater average values than other varieties across both years. For oil content, Einstein, Mercedes, PX112, Exp1302, MH11J41 and Popular had the greatest concentrations across years. Finally, for meal protein content, Sumner, Wichita, Claremore, Virginia and VSX-3 had high average concentrations across years. Exp1302 and Einstein may be the best cultivars to grow in Tennessee if oil content is more important than meal protein content while Claremore may be the best cultivar to grow in Tennessee if meal protein content is more important than oil content. None of these, however, are currently commercially available in the U.S. Since yield is the greatest factor for revenue, Hekip, Hornet, and Edimax CL are the recommended varieties for growers in Tennessee.
