On this page you will find summaries of all the 2017 beet trials harvested to date;

a)  All grazing cultivars tested

b)  Grazing cultivars tested in all sites

c)  Lifting cultivars (2016-17 average)

a) All cultivars tested.

30 cultivars of fodder beet recommended for grazing were compared in the 2016-17 trial series.  Not all cultivars were tested in all nine sites, so we have graphed their yield performance relative to the mean of the cultivar Kyros in each trial site (Figure 1.).    There was up to a 50% difference in yield potential between commercial cultivars.

Figure 1.  Mean yield of all grazing cultivars in all 2017 trial sites (relative to Kyros=100). 

b) Grazing cultivars tested at all sites.

Five cultivars of fodder beet recommended for grazing were included in all three sites in 2017 (Figure 2).   There was up five tonnes per hectare difference in yield.  The repeated comparisons at three sites means there is a high degree of accuracy with this data (LSD= 1.5).  Kyros and Bangor had higher yield than Feldherr and Brigadier.  Brigadier was less productive than the other four cultivars.

NB:  Cultivars with the same letters are not significantly different to each other.

c) Lifting cultivars (2016-17 average).

Seven cultivars of beet marketed for lifting were compared in the 2016 and 2017 seasons.  There was up to a 24% difference in yield where the yield of each cultivar was benchmarked to the mean yield of Enermax in the same site.

Figure 3.  Mean yield of all lifting cultivars in all 2016 and 2017 trial sites (relative to Enermax=100).  Note that some data is only from one trial (e.g. Rex and Gellert) so is not as reliable as data on cultivars in 6-8 trials.
