In:
Arable Farming v. 10, no. 6, p. 18-19, 23617565Summary: The errors involved in using 'tramlines' to demarcate large plots in on-farmtrials and in using yield component data from small samples are discussed. The need is stressed for adequate control plots, an indication of the level of variation and basic statistical and experimental information in presentation of results of husbandry trials. It is considered that factorial experiments and sowing date trials are not generally suitable for on-farm conditions, but that trials involving various levels of a single factor can be useful. Advice on experimental techniques for setting up and harvesting trials is given.
