Abstract

This experiment was conducted to evaluate the effect of seeding rates on the forage quality and productivity of direct-seeded whole crop rice at the experimental field of the Grassland and Forages Division, National Institute of Animal Science, RDA from 2007 to 2008. Whole crop rice variety, "Nokyang", developed by the National Institute of Crop Science, was directly seeded with four different seeding rates (30, 60, 90 and 120 kg/ha). There were no significant differences (p<0.05) found in emergence date, heading date, greenish and disease resistance based on the seeding rates. Plant height increased at higher seeding rates but the tiller number per plant decreased (p<0.05). The dry matter (DM) content showed no significant difference based on seeding rates (p<0.05) while the yield of fresh and dry matter increased with incremented seeding rates (p<0.05). Acid detergent fiber (ADF) content increased with higher seeding rates, but the neutral detergent fiber (NDF) content did not show a similar tendency. The total digestible nutrient (TDN) content was lowest with 120 kg/ha seeding rate. The grain ratio decreased at higher seeding rates. In economic analysis, the plot seeded at a rate of 60 kg/ha showed the highest income increment. Although high seeding rates increased the DM yield, a seeding rate of 60 kg/ha is recommended as the proper seeding rate for direct-seeded whole crop rice.
