Expert advice on beet re-drilling
CAPPED sugar beet crops that have not responded to rolling only warrant re-drilling if populations drop below 60,000 plants/ha, advises IACR-Brooms Barn.
Lower populations, particularly down to 20-40,000 plants/ha, are unlikely to produce more than 50% of the yield achievable with a full plant, so are more likely to justify the extra cost.
Crops re-drilled now will yield at least twice that of a poor crop that is not re-drilled, provided over 75,000 plants/ha are established. Seed availability is good and re-drilling costs the equivalent of 5-8t/ha of beet, IACR-Brooms Barn estimates. *
