Abstract
This study was conducted to determine the influence of seeding date (May 3, 13, 23, June 2, 12) on the growth characteristics yield and feed value Azuki bean(Vigna angularis W.F. Wight) from May 3, 2002 to August 3, 2002 in Jeju province. Plant height was the longest (84cm) when seeded on 13 May and was the shortest (48.4cm) when seeded on 12 June. Numbers of branches and leaves per plant, stem diameter and weight of leaves and stems per plant were the same trend with plant height. Fresh forage, fry matter, crude protein and TDN(total digestible nutrient) yield per ha at were increased to 54.6MT, 7.7MT, 1.4MT and 4.5MT, respectively, whereas decreased as seeding date was delayed and then at seeding on 12 June were decreased to 11.5MT/ha 2.12MT/ha 0.4MT/ha and 1.3MT/ha, respectively The content of crude protein, crude fat, NFE(nitrogen free extract) and TDN were incresed 17.6%∼21.3%, 3.3%∼4.5%, 34.3%∼41.4% and 56%∼64.8%, respectively, as seeding was delayed from 3 May to 13 June. Whereas the content of crude fiber and crede ash were decreased 33.8%∼23.5% and 11%∼9.3％, respectively.
