Abstract
An investigation of the relative importance in small plot pasture productivity experiments, of plot variations and of field and laboratory errors in sampling and subsampling for percentage dry matter and percentage nitrogen figures, revealed little advantage from duplicate sampling or subsampling in reducing the experimental error, which was due mainly to plot variation. The effect of sampling errors was of even less importance in the estimation of the actual yields of dry matter or of nitrogen.Keywords
