초록

This study was carried out to compare thegrowth characteristics and feed values of the whole cropsilage rice from paddy field and reclaimed paddy field. Theheading dates of tested varieties was August 8 to August30 in the paddy field, 1~2 days later than the reclaimedpaddy field's August 6 to August 29. Plant height was inthe range of 105~135 cm in paddy field, and 97~126 cmin reclaimed paddy field, respectively. The plant height ofMokyang was tallest in the paddy field, but Suwon 544was tallest in the reclaimed paddy field. The number oftiller per plant of Nokyang was largest in the paddy field.
Dry matter (DM) yield of whole crop rice ranged from15.26 to 23.24MT ha-1 in the paddy field and 11.94 to18.89 MT ha-1 in the reclaimed paddy field. The highestDM yield in both fields was attained by Mokwoo. Comparingwith the paddy field, the reclaimed paddy field achieved78~84% in the DM yield. The crude protein content ofvarieties was 8.5 to 11.6% in the reclaimed tidal land and6.7~8.7% in the paddy field. Neutral detergent fiber (NDF)of varieties in both fields ranged from 31.2 to 55.5%.
Suwon 544 recorded the highest NDF contents in both fields.
All varieties did not show any significant difference in acidicdetergent fiber (ADF) which had values ranging from 22.3to 33.2%. Total digestion nutrient (TDN) was more than60% overall in both fields. Regarding TDN yield, Mokwoorecorded 16.54 MT ha-1 in reclaimed tidal land and 12.69MT ha-1 in the paddy field, which showed the highest figureamong the varieties. These results suggest the feasibility forcultivation of the whole crop silage rice in reclaimed paddyfield, which showed 80% of the yield compared to paddyfield, and implied that Mokwoo would show the most excellentyield and feed value
