Rice Research and Extension Center General Project Descriptions
PLANT BREEDING
Breeding objectives are to develop rice varieties that combine high grain and milling yields with disease and lodging resistance, superior grain quality, and early maturity. Breeding lines are selected using the most efficient methods possible. Advanced breeding lines are tested for several years prior to their release in the Arkansas Rice Performance Trials and in the Uniform Regional Rice Nursery in Texas, Louisiana, Mississippi, Missouri, Florida and Arkansas.
SYSTEMS AGRONOMY
Rice Systems Agronomy evaluates the impacts of changing rice cropping systems. Experiments evaluate new approaches including conservation tillage, no-till, and early maturing varieties to assist farmers in maintaining their natural resource base while providing acceptable profits.
EXTENSION AGRONOMY
Rice Extension Agronomy coordinates statewide education programs on rice production technology and verification for county extension agents, consultants, and growers. Applied research is conducted on the experiment station and in growers fields concerning management practices, integrated pest management, fertilization, crop rotation, and variety performance.
AGRICULTURAL ECONOMICS
Agricultural Economics evaluates cropping system costs and returns, the economics of new or existing management practices or technologies, and the economic impacts of alternative government policies on the profitability and sustainability of rice production in Arkansas.
PLANT PATHOLOGY
Rice Plant Pathology contributes to the development of disease resistant varieties by utilizing known and novel resistance genes. Experiments are conducted on disease control strategies, as well as on metabolic factors associated with disease resistance. Research tools include studies of gene action as well as use of molecular techniques.
EXTENSION PLANT PATHOLOGY
Monitors and evaluates diseases of row-crops and vegetables and provides information for managing disease based on current research and technologies.
ENTOMOLOGY
Rice Entomology investigates all aspects of the biology, ecology, and sampling of rice insect pests. Biological, cultural, and chemical control methods are evaluated for integration into current production systems in order to reduce insect damage and losses in rice.
PHYSIOLOGY
Rice Physiology provides fundamental understanding of physiological processes as they relate to rice breeding, weed control, production practices and processing. Accomplishments include development of an adaptive, objective rice growth staging system and the finding that early draining of rice fields (2 weeks after 50% heading) does not reduce rough rice yield or milling quality.
