To evaluate the rice cultivar 'Sprice' as a forage rice for double cutting cultivation in Kyushu district, we carried out field trials at two paddy fields over two years. The agronomic characteristics were compared with those of cultivars of different plant types. The dry matter yield of 'Sprice' achieved 1,500 g mE-2 on the N- rich field. Damages from disease, insects and lodging were not observed. 'Sprice' indicated stronger lodging and shattering resistances than cv. 'Moretsu' and cv. 'Te-tep'. These results indicate that 'Sprice' has good agronomical traits as forage rice for a ratoon cropping use. Plant height was a more important characteristic for higher yielding than the tiller number.
