Nouson denka no riron oyobi jissai : nouson mondai kaiketsu no hisaku
Nougyou denka no jittai
Saikin ni okeru noumin kakusou no ugoki : konranseru nouson seiji undou
Saikin no noumin undou
Saikin no noumin undou
Saikin no kagaku ryouhou
Nouson bunka no kadai : nouson bunka chousa houkoku
Genka no nougyou denka mondai
Saikin kagakukai no kyoui
Nouson bunka no kensetsu
Katei no denka ni tsuite : fu koujou no denka
Saikin no afuganisutan
Savuēto Roshia no nōson mondai
Saikin no kyokutou soren saikin no doitsu jijou
Nouji denka kouyou
Saikin shumi no kagaku kougyoukai
Saikin no oushuu
Saikin no shina
Saikin no goushuu
Saikin no nangoku
Saikin no hantou
Saikin no doitsu
Saikin no doitsu
Saikin shinkaron
