Yuma cauliflower and broccoli crops have increased substantially in recent years. Currently more than 93% of state cauliflower and 70% of broccoli is grown in Yuma. Maricopa and Pinal counties grow the rest of state cauliflower and broccoli.

Cauliflower increased from 1400 acres in 1980 to 6200 acres in 1992, then decreased to 4200 acres in 2001. Broccoli was grown on less than 200 acres until 1985, this acreage increase linearly from less than 1000 acres in 1990 to reach 7900 acres in 2001.

Cauliflower yield increased from 100 Cwt in 1985 to 309 Cwt in 1999. Broccoli yield increased from less than 100 Cwt in 1985 to 202 Cwt in 2001.

Both cauliflower and broccoli yield increase was believed to be due to better integrated pest management, irrigation technology and soil and plant nutrient management. The increase is also attributable to newly created cauliflower and broccoli varieties.
