Best growing practices for Radiance sweet potatoes

The Vineland Research and Innovation Centre (Vineland) has conducted a series of agronomic trials in 2017 and 2018 to better understand how to grow Radiance, a new sweet potato variety. Results on spacing, days to maturity, harvesting, postharvesting and pest management have been compiled into an easy-to-read research update report (click here to read report). A few key findings include: 


•   Radiance matures 11 to 20 days earlier than commercial varieties Covington and Orleans 

•   Radiance produced significantly higher U.S. grade #1 and total marketable yields than both Covington and Orleans for early and late harvest as well as single and double row planting 

•   Double row planting can decrease total acreage while still providing high yields when a later harvest (mid-October) is desired 

•   Biodegradable black plastic mulch can increase yields in a double row planting system if an early harvest is desired 

•   Under Canadian conditions, curing for a minimum of seven days is required to adequately cure sweet potatoes
