But these procedures need to go beyond proximate feed analyses, which are not closely correlated with animal performance. Research is being conducted on several of the fol- lowing subjects: all deserve attention. • Identification of factors controlling palatability. • Anatomical characteristics as related to quality. • Isolation and study of hemicelluloses. lignin, and other carbohydrate fractions that influence forage value. • Kinds of plant proteins, their accumulation and value. • Development of efficient laboratorv procedures for measuring Preliminary data on disease and turf characteristics of new selections are obtained from small plots at Beltsville, Md. • Development of effective indicators for measuring forage intake. • Differences in quality attributable to maturity- plant parts, and season of use. • Influence of soil fertility, management, and envi- ronment on quality. • Quality characteristics of species and varieties. Improving Turfgrasses Turfgrasses occupy more than 16 million acres in the United States. Maintaining these grasses costs an estimated $3Vi> billion each year. Limited studies are being conducted on improving turfgrasses for home lawns, roadsides, cemeteries, and airports; and for parks, playgrounds, golf courses, and other recreational areas. Turfgrasses may fail to be- come established on these areas or they may deteriorate because of disease, insects, nematodes, drought, over- watering, poor drainage, heavy traffic, unfavorable temperatures, weeds, low soil fertility, soil acidity or alkalinity, mowing too frequently or too closely, not enough light, or improper use of fertilizers, herbicides, or other chemicals.
