Effects of Planting Density and Fertilization on Yield and Rutin Content in Tartary Buckwheat

摘要

This study is conducted to establish culture practices of Tartary buckwheat for mass production in Korea. Grain yield and rutin content of Tartary buckwheat are investigated under the different culture conditions. KW44 and KW53 showed higher value ofplant height, stem diameter, number of node, leaf, and branch, and brach length in a density of 30 X 30cm and 60 X 30cm, respectively. Rutin content of KW44 was highest in 60x30cm( 1,887.1 mg/100g) while that of KW53 was highest in 40x20cm( 1,569.3 mg/100g). Grain yield of both KW44 and KW53 was higher in the fertilization of N-P-K and N-K than other fertilization. Number of grain and grain weight per plant were respectively highest in the mixture of silicate with compound fertilizer but those were notmuch different with only silicate treatment. Silicate tended to increase rutin content only during early growth stages and then decreased rutin content as plant grew to mature. The highest rutin content at the 90th day was found in leaf treated with onlycompound fertilizer(1987.3 mg/100g).
