Abstract
AbstractSampling of cereal foods from bulk samples for analyses of nutrients is a well‐known procedure, but a satisfactory sampling scheme for such analyses from breeding and agronomic trials has not been defined. However, selection of five plants from each experimental plot is a common procedure among agricultural scientists. The validity of using grains from such a sample for analysis of protein was tested in the present investigation. Values obtained by analysis of pooled samples of five randomly selected ear‐heads or the average values of five such ear‐heads were not significantly different from those obtained by analyses of sampled aliquots from net plot.
