Popis: Seedlings of Dioscorea composita were treated with various combinations of ammonium sulfate, superphosphate, and potassium sulfate over a 3-year period. The tubers of the resulting plantings were tested for sapogenin content. Complete fertilization increased the sapogenin yields significantly as compared with an untreated control. Incomplete combinations or single-nutrient treatments did not significantly increase yields and, in some cases, decreased them. Yield increases were associated with increased fresh and dry weight. Although no significant effects of fertility on percentage of sapogenin were found, tubers in unfertilized plots contained the highest sapogenin in percentage.
