This study was carried out to select the promising forage crops fer forage production in paddy field of YARI, RDA, Milyang from 1999 to 2001. The species of forage crop used in this experiment were barley(5 varieties), wheat(2), rye(3) and Italian ryegrass(IRG, 3). Stages of heading, milk and yellow ripe of barley were <TEX>$20{\sim}24$</TEX> April, <TEX>$6{\sim}10$</TEX> May and <TEX>$21{\sim}24$</TEX> May, respectively. In milk to yellow ripe stage, dry matter(DM) yield of barley was <TEX>$7.89{\sim}9.66$</TEX> MT per ha, and averaged ADF and NDF contents were <TEX>$26.9{\sim}33.3%\;and\;53.1{\sim}59.2%$</TEX>, respectively. Albori and Naehanssalbori were the most promising varieties among the barley. The growth of wheat was a little late compared to that of barley, but it seemed to be crop having higher forage yield and nutritive value. In milk to yellow stage, DM yield of wheat was <TEX>$9.13{\sim}10.38$</TEX> MT per ha, and nutritive value of wheat was very good(ADF <TEX>$25.9{\sim}31.7%$</TEX> and NDF <TEX>$53.3{\sim}55.8%$</TEX>). Heading stage of rye was <TEX>$20{\sim}24$</TEX> April, and it seemed to be suitable far harvest at heading to flowering stage because of heavy lodging after flowering. In flowering stage, DM yield of rye was 13.64 MT per ha, and nutritive value of rye was the lowest among 4 species(ADF <TEX>$33.1{\sim}38.0%$</TEX> and NDF <TEX>$56.4{\sim}65.0%$</TEX>). Heading stage of early maturing IRG was 2 May and it seemed to be suitable for harvest at flowering stage of middle May in cropping system. In flowering stage, DM yield of early type IRG was 5.51 MT per ha, and averaged ADF and NDF contents were <TEX>$30.1{\sim}34.7%\;and\;59.7{\sim}60.5%$</TEX>, respectively. The results demonstrated that the promising forage crops far forage production in paddy field were rye, barley, early maturing IRG and wheat in Yeongnam region. In Southern region, rye harvesting at early May was recommended when considered middle May of rice transplanting period, and barley(Albori and Naehanssalbori) and early maturing IRG harvesting at middle May were recommended when considered late May of rice planting period. And also, wheat with high nutritive value and possibility for harvesting at late May were recommended in case of transplanting period at early June.
