changing the face of the earth to feed the world as the demand for water increases across the globe rice producers are beginning to question traditional irrigation methods and are thus left with a limited number of alternatives the competition for the earth s most precious resource has led to the concept of growing rice under center pivots and linear machines percent of water savings by using center pivots 70 60 percent water savings 50 40 30 20 10 0 2007 2008 2009 brazil usa #1 usa #2 usa #3 pakistan locations data from trials conducted between 2007-2009 in the usa brazil and pakistan pivot and flood fields were either side-by-side or near each other 120 center pivot yields as a percent of flood 100 percent of flood yields with center pivot and linear irrigation rice can be produced in areas that never before would have been considered possible however under traditional flood irrigation methods rice must be grown on a flat or nearly flat field often requiring extensive levelling or complex borders because center pivots and linears can irrigate rice on most types of terrain more of the earth s land can be put into production 80 60 40 2007 2008 2009 20 harvest not complete at time of printing 0 brazil usa #1 usa #2 usa #3 pakistan locations data from trials conducted between 2007-2009 in the usa brazil and pakistan approximate cost savings using center pivots approximate cost savings byby using center pivots 62 acre 25 62 acre 25 hectare field conventional tillage hectare field conventional tillage labor 70 percent cost savings 60 50 40 30 20 10 0 -10 -20 data from a 2009 production field in arkansas usa fertilizers fuel herbicide yield gross income net income repair maintenance variable expenses yield income
