Abstract  We have developed, by reworking complete sets of data from completed trials, a simplified recording method of determining saleable yield which can be used in all types of asparagus (Asparagus officinalis L.) agronomic trials. The method is based on counting saleable spears on every harvest day and weighing saleable spears from every tenth harvest. This gave a saleable yield value that was within 10% of the saleable yield calculated from the complete data set. There is the potential to obtain trial data much more cheaply and with adequate accuracy from grower-conducted agronomic trials.
