It's self-produced a serious shortage of feed supply source, a large number of imports each year, cultivation of forage rice technology developed to address the shortage of self-produced feed and stable feed production. From the fallow fields (including: low-yielding rice fields, marginal land) of the soil characteristics to start with selection of suitable varieties, development of high yield per unit area of soil management and fertilization techniques, including diagnosis and soil nutrient management technologies. The variety and nitrogen (N) management play a vital role in rice production and nitrogen use efficiency (NUE). In order to optimize N application patterns for variety of Taichung sen 17 of rice, we have conducted fertilization experiments with five N applied rates, include 0, 90, 150, 210 and 270 kgNha-1 in 6 locations in Taiwan. The establishment of the forage rice production adjustment mechanism, enhance the active use of paddy fields. The results reveal effect of sit and applied rate of N on grain yield for variety of Taichung sen 17 were significant (p<0.05). The N efficiency was highest under applied rate of 90 kgNha-1 among various applied rates. The higher mean temperature has significant effect on the transfer and accumulation of biomass and nitrogen to panicle of most experiments. Nevertheless, the higher mean temperature decrease the transfer of those to the grain.
