ResumoAfter World War II, the California strawberry hectarage increased greatly, reaching a maximum of 8380 ha in 19.57, with more fruit than the markets could absorb.As a result, within 5 years (1962) the area fell to its lowest post-war point, <2400 ha, and has since increased to 7690 ha in 1989, with increases in total fruit production and yield per unit hectare.The success of the California strawberry industry has been due to the breeding of a succession of improved cultivars simultaneous with the development of improved planting systems and cultural practices.This paper is concerned with the planting systems, cultural practices, and the physiological manipulation of the California strawberry cultivars.For details on the cultivars, see the cover story. California planting systemsBefore the modern California planting systems were developed, most plants were transplanted early in the spring and were harvested for 3 to 4 years in southern California and for 4 to 8 years in northern California (then, as now, under the "hill system").As the plants aged, the fruit size and quality diminished each year until the enterprise was unprofitable.The development of the summer and winter planting systems made it possible to produce and ship fruit of 'Lassen', the original California cultivar adapted to southern coastal California.Summer planting system.Summer planting, first introduced to growers in southern California in 1955, was a major improvement over spring planting and made annual planting feasible (Voth, 1955).
