Topping brussels sprout stalks increase yields
“Brussels sprouts can easily be grown here, and the flavour of locally grown sprouts that have experienced some cold weather in the fall is sweeter than that of sprouts grown in warmer conditions. For those who love Brussels sprouts, knowledge of how to grow them here is a good thing. To my knowledge, this type of research hasn’t been done in this region before.” Sideman said.
Nine cultivars of Brussels sprouts were evaluated at the farm over two years. Of the five cultivars grown in both years, Nautic, Diablo, and Jade Cross E had good yields of more than 8 ounces per stalk. Of the cultivars evaluated for one year, Gustus, Early Marvel, and Octia were promising, with high yields on quality stalks.
Sideman also investigated whether removing the top of the Brussels sprout plant increases the size of sprouts at the top of the stalk, thus improving marketable yields. She found that for some cultivars such as Diablo, Early Marvel, Gustus, and Jade Cross E, which are early and mid-season varieties, topping had the greatest positive effect.
“The practice of topping has the potential to increase yields of Brussels sprouts. It can also increase the attractiveness of each stalk, if growers are marketing entire stalks. However, topping too far in advance of harvest can reduce yields and marketability by causing plants to use energy growing new stalks.” Sideman said.
