Research continued on tropical grasses from Saccharum and related genera as sources of intensively-propagated fiber and fermentable solids. Both complete and incomplete data from the first three quarters of year 3 were reviewed. Candidate screening (for short-rotation grasses) was expanded to include six sorghum x Sudan grass hybrids developed by the Dekalb Company. Incomplete data indicate that two of the new grasses might be comparable to the NK hybrids in total biomass production and drought tolerance. Sugarcane and napier grass yield trends in year 3 includes: (a) Increased yields with delay of harvest frequency; (b) lxck of response to close spacing; (c) a superiority of napier grass over sugarcane when harvested at intervals of six months or less; and (d), a general superiority of the sugarcane variety NCo 310 over varieties PR 980 and PR 64-1791. Delayed tasseling of a wild, early-flowering S. spontaneous hybrid enabled three crosses to be made in December using commercial hybrids as female parents. Approximately 1000 seedlings were produced.
