Rice-maize rotation on the IRRI station

This is a very interesting a rice-maize crop rotation experiment that was started in 1993 on the research station of the International Rice Research Institute (IRRI; http://irri.org ).

There is now a situation in Asia where economic forces are driving a shift from continuous rice production to rice rotated with an upland crop. Rice-maize is becoming a popular rotation in some countries because as economies expand, the demand for meat and dairy products increases and that, of course, increases the demand for feed grains. In 1993, IRRI began an experiment to study the effect of switching from continuous rice in the wet season and dry season to rice in the wet season and maize in the dry season.

This particular plot that Dr. Buresh is standing in will yield about 9 tons per hectare. This is achieveable with the use of site-specific nutrient managment (SSNM; http://www.irri.org/irrc/ssnm/index.asp ) for the cultivation practices.
