Fodder Crop
Kale Crop
Kale is a well-proven fodder crop providing high yields of green fodder and a flexible utilization period that can stretch from August to the following March.
The crop has high crude protein content, good winter hardiness and can be fed to cattle and sheep. It can also be harvested and ensiled.
Dry Matter yield: 6-9 t/ha
Fresh yield: 40-60 t/ha
Dry Matter: 14-16%
Crude Protein: 15-17%
Varieties
Keeper
High yielding, winter hardy, high leaf-to-stem ratio and good nutritional value.
Kale Crop Husbandry
Lime
Target pH of 6.2-7.0
Fertiliser
N 125 kg/ha (100 units/Ac); P 30-50 kg/ha (24-40 units/Ac); K 100 kg/ha (80 units/Ac), e.g. 6 x 50 kg/acre 18-6-12. If soil Boron levels are low spray Solubor 5 kg/ha (2kg/acre) onto young crop
Weed Control
Normally none. Could use Butisan S within 48 hours after sowing.
Pest Problems
Flea Beetles can attack at emergence, and control with an application of foliar contact insecticide Watch for Slugs and Leatherjackets.
Pigeons can be troublesome in the young crop.
Disease
Club root – Very susceptible to attack, good crop rotation will avoid the problem.
Feeding Information
Kale can be grazed in situ by cattle or sheep with strip grazing as the preferred method. Feed utilization can vary from 60% increasing to 80% on good dry sites with the daily movement of the electric fence. It can also be zero grazed or ensiled for feeding later. The intake of Kale should be restricted because of the danger of Haemolytic Anaemia (nutritional redwater). This is more severe in cows than in sheep. The incidence of this problem is much greater in crops that are flowering or producing seed. Livestock fed on Kale should be supplemented with extra Iodine and Phosphorus. Ensure all diets are properly balanced for protein, energy, minerals and roughage.
