Comparative Tield and Quality of Summe Annual Grasses as Fresh-cut Forage
초록
본(本) 시험(試驗)은 새로 도입(導入)된 13개(個) 품종(品種)의 수수-수단그라스잡종(雜種)(Sorghum bicolor (L.) Moench), T-E Goldmaker 수수잡종(雜種) (S.bicolor (L.) Moench),
This experiment was conducted to provide comparative data on the newly imported thirteen sorghum-sudangrass hybrids(Sorghum bicolor(L.) Moench), TE Goldmaker sorghum hybrid (S. Bicolor (L.) Moench), NC+ 88SS sudangrass hybrid (S, bicolor (L.) Moench), Supermill pearlmillet (Pennisetum americanum (L.) Leeke) and teosinte (Euchlaena mexicana Schrad,) in comparison with the check variety Pioneer 988 sorghum-sudangrass hybrid for dry matter yield, protein content, in vitro dry matter digestibility(IVDMD), and other desirable agronomic characteristics, SX-17 and NC+855 gave significantly higher dry matter yield than the check variety. There was no significant difference in total dry matter yield of the remaining 14 varieties with the exception of teosinte and TE Goldmaker which had the lowest yield. The most varieties were moderately resistant to leaf diseases although differences exist among varieties. No diseases were found in pearlmillet and teosinte, but NC+ 88SS was very susceptible to leaf blight. The mean percent crude protein of sorghum-sudangrass hybrids was lower than that of pearlmillet and sorghum hybrid, but was higher than that of sudangrass hybrid, The IVDMD of G-83F, TE Goldmaker, teosinte and HW 5111 was higher than that of the check variety. There was no consistent relationship between the percent of crude protein and IVDMD of the summer annual grasses.
