The term weedy rice generally includes all the species of genus Oryza which has characteristics of rice and has crop in rotation with rice weeds. Weedy rice populations have been reported in many rice- growing areas in the world where the crop is directly seeded. Even though weedy rice belongs to different species and subspecies, all these plants share the ability to disseminate their grains before rice harvesting. Weedy plants can also adapt to a wide range of environmental conditions. Weedy rice grains frequently have a red pigmented pericarp and it is for this reason that the term âred riceâ is commonly adopted in international literature to identify these wild plants. This term, however, does not seem very appropriate as red-coat grains are also present in some cultivated varieties, but also absent in various weedy forms. In most rice areas the spread of weedy rice became significant mainly after the shift from rice transplanting to direct seeding, and has started to become very severe over the last 15 years, particularly in European countries, after the cultivation of weak, semi-dwarf indica-type rice varieties. The spread has generally been favoured by the planting of commercial rice seeds that contain grains of the weed.
Journals are the means of disseminating research findings. They help the common man to explore the discovery made by scholars. Journals play a very important role in maintaining periodical record of events and help us in collecting information and thus streamlining our knowledge. Generally, journals refer to collection of Scholarly articles that are published regularly and are peer reviewed. As its peer reviewed it enhances the collaborative efforts from scholars. Internationally published journals accelerate scientific research by increasing quality, competency and credibility. They increase the performance of each and every scholar there by contributing a lot to scientific community.
