Seed yield and proportion of chasmogamouseed as affected by irrigation and clipping were determined for 18 lines of sericea, Lespedeza cuneata. Seed yields were increased by irrigation regardless of clipping management; however, irrigation did not increase the percentage of chasmogamous seed. Clipping in June drastically reduced seed yield and percentage chasmogamous seed. Irrigation of clipped sericea further reduced chasmogamous seed percentage below that of nonirrigated clipped sericea. Lines reacted differently to irrigation and clipping both as to proportion of seed types and seed yield.
