  • Agronomic Management Of Fodder Beet

Agronomic management of fodder beet

Feature placeholder

Successful fodder beet cropping requires the use of Good Agronomic Practices for growing and utilising the crop, as well as good post-grazing management. Together, these will reduce the environmental impacts of fodder beet.

Key messages

Soil test to 15 cm prior to cultivation to refine N inputs.

  • If anaerobically mineralisable nitrogen (AMN) is greater than 80 μg/g then only 50 kg N/ha is required.
  • If AMN <80 μg/g, then apply 100 kg N/ha.

There is no yield response above 100 kg/ha of total N applied in fertiliser.

Timing of N application is important – 50% at sowing and 50% before canopy closure.

  • Late N (after canopy closure) will grow more leaf but not yield. It will not raise protein sufficiently for animal maintenance, nor is it economic.
  • Late N does not protect canopy from disease but does increase the leaf to bulb ratio.
  • If QT K less than 3 apply 100 kg K/ha.
  • If QT K 3–5 apply 50 kg K/ha.
  • Apply 1.5 kg B/ha when soil test for B is less than 1 ppm

Complete a soil test to confirm soil K levels. There is no specific yield response to K fertiliser if Quick Test K (QT K) level is >5.

Boron rate and timing of application has no effect on yield or incidence of B deficiency symptoms.

Maintain a healthy canopy through monitoring and control of foliar diseases to maximise yield. Prevent carry-over of disease by not sowing successive crops of fodder beet in the same paddock.

Cereals Update 230 Winter wheat cultivar mixtures under irrigated and dryland conditions in Mid Canterbury

Planting a crop consisting of multiple cereal cultivars (cultivar mixtures) enhances genetic diversity, which can improve both seasonal and long-term agronomic performance and slow or reduce disease spread. To assess the viability of this approach for feed wheat production under current commercial conditions in New Zealand, FAR conducted a series of field trials in Chertsey, Mid Canterbury, between 2021 and 2024.
