Long-grain rice cultivars Cocodrie, Wells, and XP 723 grown in three locations (Hazen, MO; Essex and Newport, AR, USA), and medium-grain rice cultivars Bengal and XP 713 grown in two locations (Jonesboro and Lodge Corner, AR, USA), were harvested and assayed for susceptibility to Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), the lesser grain borer, and Sitophilus oryzae (L.) (Coleoptera...

This research reports on a pilot project that aimed to develop a prototype ontology for plant production using Thai rice as a case study. It is expected that the developed ontology will be used as a prototype model for other efforts to develop plant production ontology in the future. The Thai Rice Production Ontology provides an organizational framework of 2322 concepts and 5603 terms, in a sys...

The study analysed adoption of improved rice production technologies in Jere Local Government Area of Borno State, Nigeria. Descriptive statistics such as frequencies and percentages were used to analyse the data. The study revealed that 98.12% of the respondents were male, 57.5% were within 41-50 years and most (33.12%) of the respondents had adult education. The study revealed that majority (...

Knowing where, when, and how much rice is planted and harvested is crucial information for understanding the effects of policy, trade, and global and technological change on food security. We developed RiceAtlas, a spatial database on the seasonal distribution of the world's rice production. It consists of data on rice planting and harvesting dates by growing season and estimates of monthly pro...

Shrimp production in Thailand has historically been undertaken in the saline and brackish waters of coastal mangroves. In recent years rising demand and prices for shrimp and falling productivity of mangrove areas have motivated an expansion of shrimp production into the fresh-water margins of river estuaries that were previously used for rice cultivation. Generalised additive models, which off...

projected global climate change may have a major influence on crop yield. the likely effects of climate change caused by increasing atmospheric carbon dioxide levels on rice yield in iran were evaluated using a mechanistic growth model for rice, gsac-rice, running under a climate change scenario predicted for a doubled-co2 (2xco2) atmosphere by the geophysical fluid dynamics laboratory (gfd...

Rice production in the country is characterized by two production seasons namely, mainseason and off-season. Officially, the two production seasons data usually aggregated to form single data of domestic rice supply for the nation. This aggregation is refers to as all-season rice production. All the previous studies estimated supply equation based on the aggregated data thereby denying the oppo...

Since the mid-1970s, rice consumption in Nigeria has risen tremendously at about 10% per annum due to changes in consumer preference. Most public and private sector interventions programmes at increasing the productive capacities of various factors within the system notwithstanding, domestic production has not been able to meet the local demand leading to considerable import, which today stood ...

Background: Aflatoxins are toxic fungal metabolites enable to contaminate a wide range of natural substrates. This contamination can be host-specific for different plant species. In this study, the ability of a toxigenic Aspergillus parasiticus to produce various aflatoxins on major Iranian cereals was evaluated with special focus on plant susceptibility to toxin production at cultivar level. M...

Rice (Oryza sativa L.) has supported a greater number of people for a longer period of time than any other crop since it was domesticated between 8,000 to 10,000 years ago (Greenland, 1997). At present, rice is the staple food for more people than wheat, and 90 percent of total rice production is grown and consumed in Asia (Evans, 1998). Unlike maize or wheat, less than five percent of total ri...
