Newer varieties mean spring OSR is worth another look

摘要

Growers are being urged to reconsider oilseed rape in their spring cropping mix, with newer varieties offering a step up in yield and increased vigour.With the challenging autumn conditions, many arable growers are now considering their drilling options for next spring, to fill the gap left by unplanted winter crops. One breeder believes spring OSR provides an opportunity.Mike Farr, DSV area manager, points out that the new spring varieties offer greater disease and pest resistance than winter-sown cultivars."The occurrence of fungal diseases is much less in spring rapeseed than winter rapeseed, so disease control is rarely necessary," he says.Phoma risk is not a problem, as the spring crop has a short vegetative period and specific temperature requirements are not met, as the crop only takes about 150 days to grow.
