Choose Fodder Beet Varieties with High Energy Yield

Farmers sowing fodder beet crops for feeding to livestock, should select varieties based on their potential for high energy yields and low dirt tares, advises Limagrain’s Martin Titley.

Fodder beet’s high sugar levels and palatability make it a good forage choice for livestock,” says Mr Titley. “However, energy yields can differ considerably between varieties.”

In Limagrain’s 2013 fodder beet trial, in which 14 commercial varieties were evaluated, the highest yielding variety was Blizzard, yielding 20.43 t/ha of dry matter. This was a tonne more of dry matter than Magnum and over 4 tonnes more than Feldherr.

Mr Titley adds: “Taking into account the energy density of each variety and calculating the energy yield per hectare: Blizzard provided 11,700 MJ/ha more metabolisable energy than Magnum, and nearly 58,000 MJ/ha more than Feldherr.

“As well as energy potential, dirt tare is important. Sugar beet, and some fodder beet varieties with similar genetics, can be very ‘fangy’ and/or develop cracks when growing. Soil then becomes trapped on the beet, and is difficult to remove even with washing.

“Limagrain’s fodder beet programme has always concentrated on developing smooth-skinned beet without fangs, to reduce soil contamination in livestock rations.

Mr Titley adds: “Blizzard has performed consistently well in trials over the years. It sits deeper in the ground than some, and so needs a sugar-beet harvester for lifting, and not a top-lifter. It has a higher DM content which makes it less prone to cracking in frost, and more winter hardy overall. Its smooth root gives it a low dirt tare.”
