Abstract
This experiment was conducted to evaluate the effect of direct seeding time on the yield and quality of whole crop rice at experimental field of Grassland and Forages Research Center, National Institute of Animal Science, RDA from 2005 to 2006. Whole crop rice variety, "Namil", was direct seeded at five different calender date (25 April, 10 May, 25 May, 4 June and transplanted at 25 May). The heading date was delayed at late seeding date. Crude protein (CP) was increased with delayed direct seeding date. The content of ADF (acid detergent fiber) and NDF(neutral detergent fiber) increased with delayed seeding date. The average TDN (total digestible nutrient) content was 61.5% and it also decreased with delayed direct seeding date. The highest DM (dry matter) yield was seeded at 25 April and transplanted at 25 May, 15,185 and 15,815 kg/ha, respectively. Although delayed direct seeding date decrease the DM yield, mid-May will be recommendable as proper direct seeding date.
