Grain specific weight is measured in kg/hectolitre, and is an indication of the density of the grain.
Many markets require oat grains to be at a minimum specific weight to be utilized.
Specific weight is predominantly a genetic trait of varieties, but poor crop nutrition and application can reduce specific weight.
Nitrogen used at above optimum levels can cause lodging of a crop which leads to germinating of the grains in the ear, and as a consequence, a lower specific weight. Variable applications of nitrogen with the optimum rate across the field can be used to create a more homogeneous crop.
Potassium increases the thickness and strength of wheat straw and thereby its resistance to lodging. Spring applications of potassium will ensure a good canopy structure least prone to lodging.
In high rainfall seasons, oats are susceptible to moulds and the toxins that they produce. Mould toxins are harmful to both humans and animals, and their maximum contents in the crop are defined by EU legislation. A farmer can avoid moulds through good crop rotation, drying at harvest, use of high-quality disease free seed, seed treatment, and variety choices.
