The journal Paddy and Water Environment aims to advance the science and technology of water and environment-related disciplines in paddy-farming. The scope extends broadly to paddy-farming related sci...
Paddy rice is one of the most important crops in Japan and it needs much water to grow, especially for water reserves for paddy irrigation. The test site “Owari Seibu” doesn’t have enough irrigation...
Eight high biomass sugarcane clones and two commercial sugarcane cultivars were planted in upland and paddy fields in Tsukuba in 2003-2005 to identify a new crop suitable for abandoned paddy fields i...
We have investigated the use of air-assisted strip seeding for direct seeding in flooded paddy fields. A seeder was developed using a commercially available granule applicator remodelled for tractor i...
Paddy field rice can conserve N in the soil under flooded conditions. However, residual soil N represents a potential environment concern when fields are no longer flooded. Winter annual grass cover c...
Land consolidation involving the joining of small paddy fields to form a large-size field has been promoted recently in Japan in order to increase the efficiency of rice production. However, the varia...
Labor-saving for fertilization has been strongly desired due to the shortage in labor and increasing scale of farming for rice cultivation. In order to clear these problems, the effect of application ...
The apple snail Pomacea canaliculata becomes a much more serious pest in direct-sown rice fields than in transplanted fields. In south Japan, it represents an important constraint on the implementatio...
Uplandization” is the process that changes the physical and chemical properties in a paddy field into those of an upland field. There is a transitional period when a paddy field is converted to an upl...
The juvenile phase and photoperiodic sensitivity of 13 Japanese paddy rice varieties were investigated. The duration of juvenile phase was determined by counting the days of insensitivity to a short-d...
The purpose of this experiment was to examine whether the foliar application of urea is effective as a countermeasure against excess moisture injury of soybeans [Glycine max (L.) Merr.]. During the fl...
Emergence and establishment of seedling of paddy rice sown into flooded soil are poor but promoted when seeds are coated with O2 generator CaO2. It has been commonly understood that this is because C...
The present study was conducted to develop the basal fertilizer application methods which mitigate the damage due to cool weather at booting stage by investigating the relationships between the change...
Varietal difference of lodging resistance in paddy rice was studied using nine Japanese cultivars and thirteen foreign cultivars (cv. Kamenoo : KA, Aikoku : AK, Koshihikari : KO, Dobashi 1 : DO, Fujim...
