Popis:	Crop yield has to increase to meet the expanding demand for food, feed and bio-energy, caused by world population growth and increasing wealth. Raising sugar yield is also the key to sustaining the profitability of the sugar beet crop. This paper describes the factors that impacted on yield differences between 26 ‘top’ and 26 ‘average’ growers based on four years yield data (2000–2004). In 2006 and 2007, the top growers had 20% higher sugar yields compared to their neighbouring average growers. Heterodera schachtii and Beet necrotic yellow vein virus (BNYVV) were mainly found on clay soils. Top growers on clay soil had significantly lower infestation levels of H. schachtii (4.4x lower, P = 0.008), BNYVV (2.7x lower, P = 0.016) and other foliar symptoms (Pseudomonas, Phoma betae and Verticillium spp. combined) (1.5x lower, P
