Seed Yield, Oil and Protein Content, and Pollinator Potential of Winter Canola
Abstract
Canola (Brassica napus L.) is an oilseed crop and is a source of healthy cooking-oil, animal feed byproducts, biodiesel, and a good cover crop, rotation with winter wheat and habitat for pollinators. The increasing demand for winter canola has been fulfilled by introducing hybrid varieties with higher yield and adapting the varieties that grow during the winter season. As new varieties are introduced there is a continuous need to identify how they perform in new areas like Tennessee where less research has been performed. Therefore, a study was conducted during 2020–2021 (Year 1) and 2021–2022 (Year 2) in Tennessee State University Agricultural Research station Ashland City, TN with seventeen (9 hybrid + 8 open-pollinated) varieties in a randomized complete block design with four replications across both years in order to calculate plant count, canopy cover, winter mortality, seed yield, oil and protein content. Although, plant count and winter mortality of the hybrids were less but canopy cover was higher. Across both years among all varieties, seed yield ranged from 1976-3295 kg ha-1, oil content ranged from 45-48%, and protein ranged from 18-21%. Generally hybrid varieties are recommended for yield and oil prospective whereas open-pollinated varieties are recommended for the protein purpose. Recommended winter canola varieties from this study was CP1077WC which came under hybrids. Pan trap collected higher number of pollinators than the sticky trap and sweet net in year 1. Afternoon time collected significantly higher number of pollinators in year 2.
