In this paper, a practical scheme for assimilation of multi-temporal and multi-polarization ENVISAT ASAR data in rice crop model to map rice yield has been presented. To achieve this, rice distribution information should be obtained first by rice mapping method to retrieve rice fields from ASAR images, and then an assimilation method is applied to use the temporal single-polarized rice backscat...

Red rice in the US is an aggressive weed that reduces the yield of rice and contaminates its grain. It is the same species as rice, which provides an opportunity for intercrossing. This genetic similarity complicates the management of red rice in fields and rice mills, but also indicates a potential for its use in rice breeding or niche markets. Physicochemical and cooking quality characteristi...

The rice water weevil, Lissorhoptrus oryzophilus, is the most destructive insect pest of rice in the United States. Early planting of rice to avoid damaging infestations of the rice water weevil has long been suggested as a management tactic. A five-year study was conducted to characterize the influence of rice planting date on rice water weevil management in light of recent trends toward earli...

The occurrence of sterigmatocystin (STC) in paddy and processed rice samples produced in Italy was surveyed. After extraction and purification, STC was analysed using HPLC-MS/MS. STC was detected in all paddy rice samples (n = 49), in the range 0.29-15.85 μg·kg-1. As regards processed rice, a widespread contamination was found in brown and parboiled rice. All the brown rice samples were contami...

This paper presents the effect of electric field distribution which is an electric field intensity analysis. Consideration of the dielectric heating of grains and insects, the rice and rice weevils are utilized for dielectric heating analysis. Furthermore, this analysis compares the effect of electric field distribution in rice and rice weevil. In this simulation, two copper plates are used to ...

Background: Globally, hot cooked refined rice is consumed in large quantities and is a major contributor to dietary glycaemic load. This study aimed to compare the glycaemic potency of hot- and cold-stored parboiled rice to widely available medium-grain white rice. Method: Twenty-eight healthy volunteers participated in a three-treatment experiment where postprandial blood glucose was measured ...

background: rice is one of the crops, which are prone to be contaminated with toxigenic fungi and their mycotoxins. this study aimed to investigate the natural occurrence of t-2 toxin in domestic and imported rice in iran. methods: in a cross-sectional descriptive study in winter 2007, 140 samples of imported rice (125 samples of thai and 25 sam­ples of pakistani rice) and 60 samples of iranian...

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...

Rice has fed more people than any other crop has for thousands of years. The ancient Indian name for rice, Dhanya, means “sustenance for the human race.” Especially in much of Asia, life without rice has been unthinkable. Rice feeds more than half of the world population, but most rice is consumed within 10 miles of where it is produced. Rice is the 2nd largest crop in planting acreage after wh...
