Phosphorus and sugar-beet yield
Phosphorus is a component of nucleic acids and lipids and is important in the production and transport of sugars, fat and protein during sugar beet production.
Phosphorus is especially important during early root development. A good supply of phosphorus ensures rapid root growth and good uptake of other nutrients.
Phosphorus is very immobile in the soil and is only taken up within 1-2 mm from the root. Placement of phosphorus will often give a higher uptake efficiency and result in a higher availability of phosphorus. Phosphorus availability is especially affected by cold soils where the mineralization of phosphorus is low.
Phosphorus deficiency inhibits growth of the sugar beet plants giving them a stunted, stiff appearance.
The colour of the leaves ranges from dark green to dull blue-green.
Furthermore, anthocyanin may be visible which gives a red/violet colour to the leaf veins and margins.

How to increase sugar beet yield
The two key components of sugar beet yield are the weight of sugar beet roots and the % sugar content of them. The combination of a high root yield and high sugar content will give the highest yield of sugar per hectare
Nitrogen and sugar beet yield
Nitrogen is the nutrient with the greatest influence on sugar beet yield. It is a key component of enzymes, vitamins, chlorophyll and other cell constituents, which are essential for crop growth and yield.
Potassium and sodium and sugar beet yield
Potassium and sodium both have an important role in the regulation of water within the plant with deficiency having effects on the growth, development and yield.
Magnesium and sulphur effects on sugar beet yield
Magnesium and sulphur are both important components of chlorophyll, among other other roles and are therefore vital for photosynthesis and yield development.
Micronutrients and sugar beet yield
Micronutrients, particularly boron, copper, manganese and zinc all have essential roles in sugar beet and a deficiency of any one will result in reduced yield or quality.
