Rhizosphere microbial community compositions as affected by management systems.

FAO has been trying to enhance perennial agriculture, especially in developing countries, and that includes developing perennial versions of currently annual crops. This is because 1) the agricultural system has financial advantages for farmers over annual agriculture, 2) crop yields not consistently high but consistent, and for other benefits. Perennial agriculture has advantage also for environmental conservation; 1) year round soil protection and lack of soil disturbance, 2) deep rooting systems, 3) stable soil structure and soil health, and others. However, no examination has been made for the effect of the agriculture on soil ecosystem. Thus, we compared microbial community compositions of green pepper rhizosphere among perennial, annual, and annual + no tillage management systems.
