有機物連用圃場におけるダイコンの品質 Quality of Japanese Radish (Raphan us sativus L.) under the Compost Successive Appication 浦嶋, 泰文 ウラシマ, ヤスフミ URASHIMA, Yasufumi SUGA, Yuko 須賀, 有子 スガ, ユウコ 福永, 亜矢子 フクナガ, アヤコ FUKUNAGA, Ayako 池田, 順一 イケダ, ジュンイチ IKEDA, Jumichi 堀, 兼明 ホリ, カネアキ HORI, Kaneaki Radish (Raphanus sativus L.) compost Nitrate nitrogen sugar Isothiocyanate Ascorbic acid Radish (Raphanus sativus L.) compost Nitrate nitrogen sugar Isothiocyanate Ascorbic acid The effect of organic matter application (organic farming) on the quality of radish was examined. The organic matter used was cattle feces compost and hog feces compost. Radish was cultivated in the experimental field, which had been continuously applied organic matter or chemical fertilizer for eight years. After the harvest, root size, leaf color of radish and the contents of nitrate, isothiocyanate, sugars and ascorbic acid as indices of interior quality were measured. 1. The growth and leaf color of radish were superior in the continuously compost applied plots with greater rate of application. The growth and leaf color value of radish of the mulching plot were greater than those of the plot without mulching, under identical application rate. 2. The organic fertilization showed no significant effect on the quality of radish than that of the chemical fertilizer application. There was the significant relation with the amount of applied fertilizer between the quality and growth of radish. 独立行政法人 農業技術研究機構 近畿中国四国農業研究センター 2002-03-01 jpn departmental bulletin paper VoR https://doi.org/10.24514/00001459 https://repository.naro.go.jp/records/1499 10.24514/00001459 10.24514/00001459 1347-1244 近畿中国四国農業研究センター研究報告 BULLETIN of THE NATIONAL AGRICULTURAL RESEARCH CENTER for WESTERN REGION 1 61 75 https://repository.naro.go.jp/record/1499/files/nwarc_report_No1p61-75p.pdf application/pdf 525.6 kB 2019-03-15
