Especially, V-furrow direct seeding has started to be adopted mainly in Aichi prefecture. To promote this adaptation, knowledge of water demands in winter are needed, because V- furrow direct seeding require field preparations in the winter season. Therefore, this study analyzed the actual conditions of the water supply for field preparations. The following results were obtained: (1) the lots for field preparation in the winter season equivalent to 10.1% of the total lots of the study area, (2) the area for field preparation in the winter season equivalent to 15.3% of the total area of the study area, and (3) the total amount of water supplied for field preparations was approximately 150 mm, including the effective rainfall.}, pages = {105--110}, title = {不耕起V溝直播栽培における冬季代かき用供給水量}, year = {2018}, yomi = {タニモト, タケシ and シンドウ, ソウジ and オニマル, タツジ and オオワダ, タツアキ} }
