ORCHARDGRASS is the most productive grass in irrigated pastures of the Intermountain Region and is increasing in importance over a much larger area. A strain with a lower water requirement would be of value not only in the irrigated west but wherever water is sometimes a limiting factor in plant growth. The prospect of undertaking to breed a strain of orchardgrass having a lower water requirement gave emphasis to the need of more critical information on technique. The present paper reports the effects on water requirement of five factors, each at two levels, and their interactions. The factors are container, water, nitrogen, mulch, and genotype. The objective was to measure the effects of fliese factors and from that appraisal attempt to arrive at the most satisfactory procedure for conducting water requirement studies as one phase of an orchardgrass breeding program.
