Abstract

A procedure combining both random and systematic methods of sampling was developed for sampling experimental plots of alfalfa for insecticide residues. It was found that a single chemical analysis made form a 20-composite sample taken from a 20-by 40-foot plot was about ideal for determining insecticide residues on alfalfa. The procedures and statistical methods are outlined in detail.
