Breakdown of changes in wheat yield from irrigation and weather in 2000-09 in the major wheat-producing states. Green bars represent the percent of yield that is gained due to irrigation. Orange and gray bars represent the percent of yield that is lost due to temperature and precipitation respectively. For each state, the figure shows how far predicted yields generated from the Full Model are from predicted yields generated when (i) Irrigation is kept at average 1970–71 values; green bars (ii) Temperature variables are kept at average 1970–71 values; orange bars (iii) Precipitation variables are kept at average 1970–71 values; gray bars or (iii) Irrigation as well as weather variables are kept at average 1970–71 values; blue triangles.
