|
This study was conducted to determine the influence of seeding date on growth, characteristic yield and chemical composition of Cassia mimosoides var. nomame from March 11, 1998 to December 1998 in Cheju Province. Days to flowering were lessened as seeding date was delayed. The plant height of Cassia mimosoides var. nomame was the longest when seeded on 31 March(99㎝) than at the other seeding date. When seeded before 31 March, stem diameter, number of leaves increased as seeding date was late, while number of branches remained constant. And numbers of withering leaves were increased as seeding date was earlier. Fresh forage yield per ha, for Cassia mimosoides var. nomame was the greatest (46.60MT) at 31 March seeding, the second was 43.97 MT at 10 April seeding and the reduced the 34.73MT at 11 March seeding. Also dry matter yield, crude protein yield and total digestible nutrient(TDN) yield per ha was nearly the same tendency. Crude protein, crude fat percent were the greatest at 31 March seeding and than decreased with further increased at seeding date. Crude ash and crude fiber percent tended to decrease as seeding date was delayed. Nitrogen free extract (NFE) and TDN percent tended to increase as seeding date was delayed.
