Combine speed strategies in cereal harvesting 1. adjustment for long term crop variability



Combine speed strategies in cereal harvesting 1. adjustment for long term crop variability



Journal of Agricultural Engineering Research 31(3): 243-254



Previous simulation models of cereal harvesting have computed a single optimum combine speed for all crops in all years on a particular farm. This study consists of an assessment of the economic benefits of selecting a different speed in different harvest years, or for different crops, varieties or fields in the same year. This required an examination of available data on crop parameters such as straw yield. Results showed only small benefits from such a strategy arising from typical straw yield variations in winter wheat or spring barley, or between these two crops; however, benefits would be substantial in certain circumstances, including when there are high levels of weed infestation, and where there is a wide range of soil types on a farm.
