Determining the optimal population density of sugarbeet crops in England [Full subscriber]

Eleven experiments were conducted at seven sites in England from 2006 to 2008 to investigate the sugarbeet yield response to plant populations resulting from different seed rates. Experiments were made on loamy sand, sandy loam, sandy clay loam and silt clay loam soils to test whether different soil types need different optimal plant populations. All experiments were harvested by machine. The various seed rates resulted in plant populations ranging from 40,000 to 180,000 per hectare although this range was not achieved in every experiment. Sugar concentration and dirt tares tended to increase as the population density increased whereas sodium, potassium…
