Nitrogen (N) fertilizers are a major input cost in rice production, and its excess application leads to major environmental pollution. Development of rice varieties with improved nitrogen use efficiency (NUE) is essential for sustainable agriculture. Here, we report the results of field evaluations of marker-free transgenic NERICA4 (New Rice for Africa 4) rice lines overexpressing barley alanin...

Red rice and rice belong to the same genus and species. Both are selfpollinated plants, but some outcrossing has been documented. Due to outcrossing, there are chances of resistant gene transfer from herbicide-resistant rice to red rice, which may increase the weediness of red rice. In 2000 simultaneous flowering was observed between Clearfield® CL2551 and red rice at the Rice Research and Exte...

Rice blast, an erratic niche disease incited by Magnaporthe grisea Cav., frequently limits rough rice yields and grower cultivar options in Arkansas rice production areas. Scientists poorly understand why some blast-susceptible varieties such as ‘Newbonnet’, ‘LaGrue’, ‘Mars’, and ‘Cypress’ become increasingly more blast resistant if grown in continuously flooded soil. A greenhouse depth-of-floo...

Transgenic rice containing insecticidal protein(s) from Bt (Bacillus thuringiensis) effectively control lepidopteran pests under laboratory and field conditions. However, Bt rice has not been widely commercialized. A major concern regarding the deployment of Bt rice is its potential impact on non-target arthropods, including herbivorous insect pests and biological control agents (predators and ...

Rice flour, corn flour and deoiled rice bran blends were used to prepare ready-to-eat extrudates

crop rotation is one of the essential practices in sustainable agricultural systems, be-cause of its effects on soil fertility and other benefits including a reduction in weed compe-tition. a field experiment was conducted at chaparsar rice research station, tonekabon, iran, from 2002 to 2003 to assess the influence of crop rotation, time of planting, and till-age depth on rice (oryza sativa l....

Free standing and vertically aligned silicon rice-straw- like array emitters were fabricated by modified electroless metal deposition (EMD), using HF-H(2)O(2) as an etching solution to reduce the emitter density and to make the emitter end of the formed silicon rice-straw arrays shaper than those formed by conventional EMD. These silicon rice-straw array emitters can be turned on at E(0) = 4.7 ...

Rice crop height is an important agronomic trait linked to plant type and yield potential. This research developed an automatic image processing technique to detect rice crop height based on images taken by a digital camera attached to a field server. The camera acquires rice paddy images daily at a consistent time of day. The images include the rice plants and a marker bar used to provide a he...

An investigation of the migration of 3-chloro-p-toluidine hydrochloride (CPTH) on treated rice baits to soils in Louisiana rice fields was completed. The persistence of free CPTH in these soils was evaluated with field and laboratory experiments. These soils were also screened for the presence of CPTH degradation products. Soils treated with CPTHfortified rice bait and aqueous solutions of CPTH...

Rice is a major staple food for nearly half of the world's population and has a considerable contribution to the global agricultural economy. While spaceborne Synthetic Aperture Radar (SAR) data have proved to have great potential to provide rice cultivation area, few studies have been performed to provide practical information that meets the user requirements. In rice growing regions where the...
