FACTORS AFFECTING THE GERMINATION AND ESTABLISHMENT OF MONOGERM SUGAR BEET
2.5 Alternative methods of establishing beet
2.5.1 Transplanting
Scott & Bremner (1966) investigated the potential of transplanting with multigerm varieties as an alternative to contemporary practises and found that an extra ten tonnes/ha of roots and more tops could be obtained. The technique resulted in more fangy and globular roots developing, but the desired plant populations were easily obtained. The larger leaf area duration of the transplants made them more drought sensitive, but in the experiment drought did not seriously check yield. High populations were not required as it was realised that it was the period of ground cover and not the L.A.I. obtained that had the main effect on yield.
In 1966 it was postulated that commercial success would be possible if suitable mechanisation at an acceptable cost could be developed but it was not forthcoming in the U.K. However, in Japan and Bavaria transplanting is used.
More recently ADAS have started to re-investigate the technique and preliminary trials with monogerm varieties in paper mini-pots show promise of a 40% yield improvement (Farmers' Weekly 1980).
Some other advantages have been noted, namely a reduced dirt tare and better root shape which contrasts with Scott & Bremmer, but handling costs are still prohibitive.
