Green Globe is a valuable summer feed option on dairy farms to help maximise milk production. Plant 2/3 of the crop area in the early-maturing Barkant® turnip (60-90 days maturity) and 1/3 in late-maturing Green Globe turnip (90-120 days maturity). Planting both turnip cultivars on the same day provides a variation in the spread of maturity, whereby the turnips can be grazed over a longer period from 60–120 days.
Using the two turnip cultivars to spread maturity, can be a great way to maintain feed quality while pushing summer brassicas out into late summer. Removes concerns regarding the feed quality of turnip crop declining due to trying hold onto an early-maturing cultivar for too long or reduced crop yield from grazing a late-maturing crop too early. Green Globe and Barkant turnips complement each other well.

LATE AUTUMN/WINTER FEED
Green Globe turnips are an ideal late autumn/winter feed option in more challenging environments. Sown in late summer it can be grazed 90-120 days after sowing and does not require a specific ripening period. There are a number of situations where Green Globe could be incorporated, whether as part of a development plan (e.g. breaking in country), lower fertility soils or more challenging topography.
“Green Globe turnips are reliable in country not fertile enough for swedes and have the ability to hold feed quality through to August for in-lamb ewes”, says Geoffrey. He runs sheep and beef on the 5500 ha Mataura River high country property, Cattle Flat Station. Green Globe turnips are sown in late December and are grazed in early spring.
