This study was conducted to determine the optimal planting time of corn to make possible the control of sod growth by only mowing immediately before planting. Clover sods established in autumn or spring were mowed on 4 different dates, after which the corn cultivar 'LG2290' was planted by the no-till method. Weeds were suppressed regardless of planting time when the clover sod was established in the autumn. However, the earliest planting（May 2） caused corn growth depression due to interference with the regrown clover. Consequently, the density of corn at harvest decreased by 60 ％ of the initial value, resulting in a much lower yield than those from the other 3 planting times. Though the interference by clover was found in the other 3 planting treatments, the degree of corn growth depression was decreased with delayed planting. The latest planting （May 31）produced the high yield of 16 t DM ha^-１ in spite of its low nitrogen application（50kg ha^-１）. When the clover sod was established in the spring, weed depression was found only in the May 31 planting. Moreover, the corn appeared N-deficient regardless of planting time and the yields were much lower than those from autumn-established clover.\n","subitem_description_type":"Abstract"},{"subitem_description":"シロクローバを用いたリビングマルチを飼料用トウモロコシの無農薬栽培に適用するには, クローバの生育を除草剤を用いずに制御する必要がある。本試験では, 刈り払いのみでの制御が可能となるトウモロコシの播種期を明らかにするため, 秋または春に播種したクローバによる被覆を異なる4期で刈り払い, その直後にトウモロコシを不耕起播種した。秋播きのクローバはトウモロコシの播種日にかかわらず雑草を効果的に抑圧した。しかし, 最も早い5月2日播種では, トウモロコシも著しく抑圧され, 収穫時のトウモロコシの密度は初期生育時の60 %程度までに減少し, その収量は低かった。クローバによる抑圧は5月11 日以降の播種でもみられたが, その程度は播種日が遅くなるに伴い低下した。このため, トウモロコシの収量は遅播きほど増加し, 最も遅い5月31 日播種では5㎏/10a の低Ｎ施用にもかかわらず1.6 ｔ/10a の高い乾物収量が得られた。一方, 春播きのクローバでは, 最も遅い5月31 日にトウモロコシを播種した場合にのみ, 雑草抑圧効果が認められた。さらに, 播種日にかかわらずトウモロコシにＮ欠乏症がみられ, その収量は秋播きのクローバにおけるよりも著しく少なかった。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001174","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人
