Crop varieties for irrigation : cereals, oilseeds, pulses, forages, specialty crops. : A98-4/75-2002E-PDF

"The yield comparison tables are compiled from irrigated yield tests conducted by the Canada-Saskatchewan Irrigation Diversification Centre (CSIDC). The data used in the tables are from irrigated co-operative (pre-registration) trials, regional yield trials, agronomic and observational trials, and producer funded yield trials. The trials are conducted on small replicated plots using specialized plot equipment. A high level of management is applied to eliminate differences caused by soil variability, weed pressure, or disease. The aim is to make conditions as uniform as possible so that yield differences are due to the varieties themselves, and not some other factor. Emphasis is placed on testing those varieties with good lodging tolerance, suitable disease resistance, and ease of harvest under irrigated production. Crop varieties respond differently from year to year. The highest yielding variety one year may be one of the lowest yielding in another year (for example it may mature late and be at risk of frost). Choosing the highest yielding variety is no guarantee that it will give the highest yield for this season, or for your farm. A choice of one of the higher ranked varieties may be suitable, especially if some other characteristic such as disease resistance or early maturity is desired."--page [1].
