s:523:"TI Analysing data from participatory on-farm trials 
AU Coe, R. 
AB Researchers carrying out participatory on-farm trials, particularly variety selec-tion trials, often have difficulty analyzing the resulting data. The irregularity of designs means that some of the standard tools based on analysis of variance are not appropriate. In this paper some simple extensions to analysis of variance, using general linear models and linear mixed models, are shown to facili- tate insightful analysis of these awkward designs.
