California Agriculture 38(1):10-11.
Not available – first paragraph follows:
Most of California's fresh market tomatoes, a crop valued at $161.1 million in 1981, are grown in San Diego, Orange, Ventura, San Joaquin, Merced, and Fresno counties. In southern California, growers may establish tomato plantings from early February through mid-July. Planting dates (spring, summer, fall) are influenced by the market, especially the spring and fall crops, which usually are more profitable.
