Understanding farmers’ perception is important in the development of sustainable and cost-effective integrated pest management strategies. Hence, farmers’ perception on rice insect pests and pesticide use was evaluated by selected 112 farmers composed of 77% males and 23% females, over the rice growing areas of North Cotabato, Central Mindanao, Philippines. 62% of farmers that were interviewed ...

Because rice feeds half of the world's population, a secure global food supply depends on sustainable rice production. Here we test whether the co-cultivation of rice and fish into one "rice-fish system" (RFS; fish refers to aquatic animals in this article) could help sustain rice production. We examined intensive and traditional RFSs that have been widely practiced in China. We found that rice...

Rice stink bug (RSB), Oebalus pugnax F., is an important pest of heading rice in the United States. Little is known about plant volatiles production following herbivory by rice stink bug. RSB feeding induced volatiles production in different RSB host grasses and rice varieties, and may help explain RSB movement to heading rice. Limonene and methyl salicylate (MeSA) were found in varying amounts...

Agricultural risk, especially the risk assessment, partition and economic loss estimation of specific and main crops, maize, wheat and rice, is widely touted in China as a means of improving the effective productivity. The main objective of this article is to perform a detailed analysis of the stability and comparative advantage of rice production in 30 provinces on the basis of relative rice p...

Productivity of most common Iraqi rice cultivar was low compared to an average production among major rice-producing countries, this may be due to inadequacy of knowledge and skills of rice farmers about rice cultivation practices. The study was conducted in Mahanawiyah district of AL-Qadisiya Province in Iraq, to assess knowledge level of rice farmers about some rice cultivation practices .The...

This study examines the impact of two decades of neoliberal policy reform on food production and household livelihood security in three West African countries. The rice sectors in The Gambia, Côte d'Ivoire, and Mali are scrutinized as well as cotton and its relationship to sorghum production in Mali. Although market reforms were intended to improve food production, the net result was an increas...

Many cultivation practices have been improved in order to decrease environmental burdens of paddy rice production in Japan. Therefore, the importance of life cycle assessment (LCA) to assess the environmental impacts of whole production systems particularly that of rice production has increased. However, the applications of LCA to rice production are still limited, although rice is the staple f...

As an economy experiences high growth rates, some sections of the population enjoy a more than proportionate rise in income. This leads to an increased allocation of resources towards the production of luxury goods. Since the production of luxury goods often requiresmore resources than the production of necessary goods, itmay reduce not only the production of necessary goods, but also total pro...

The management and improvement of paddy soils fertility are key factors for the future capacity of rice production. The return of rice straw to paddy soils is the best alternative to the application of industrial fertilizers for rice production sustainability. The best strategy for applying rice straw to improve soil nutritional capacity during rice growth has not yet been investigated. We comp...
