Study on the Cultivation Method of New Rice Variety, 'Nokyang' for whole crop

摘要

This experiment was conducted to evaluate the effect of seeding rate on the quality and yield of whole crop rice variety, "Nokyang". Whole crop rice variety, "Nokyong", was direct seeded at 25 April. The seeding rate were four level(30, 60, 90, and 120kg/ha). There was not found significantly difference plant height and dry matter(DM) content among seeding rate. The average DM content was 44.1%. Dry matter yield of 30kg/ha seeding rate plot was decreased compared to others treatment. The CP yield of 60kg/ha seeding rate plot was the highest among treatments. Acid detergent fiber(ADF) and neutral detergent fiber(NDF) content have not been affected in relation to seeding rate. The content of TDN(total digestible nutrient) increased with increased seeding rate until 90kg/ha seeding rate. The highest fresh and DM yield showed at 120kg/ha seeding rate. But there was not found significantly difference among 60,90 and 120kg/ha seeding rate. Although high seeding rate increase the DM yield, 60kg/ha seeding rate will be recommendable as proper seeding rate for whole crop rice.
