<P> Agriculture is one of the prominent elements of the state 's economy : California leads the nation in the production of fruits , vegetables , wines and nuts . The state 's most valuable crops are cannabis , nuts , grapes , cotton , flowers , and oranges . California produces the major share of U.S. domestic wine . Dairy products contribute the single largest share of farm income . California 's farms are highly productive as a result of good soil , a long growing season , the use of modern agricultural methods and extensive irrigation . Irrigation is critical since the long dry summers would not allow most crops to grow here -- California Indians had almost no agriculture because of this . Extensive and expensive irrigation systems including furrow `` gravity '' irrigation , sprinkler and drip irrigation systems have been developed to supply the extensive irrigation needs of California . Illegal immigration to the United States has been traditionally drawn to the state , in part , because corporations face intense pressure to control labor costs by using illegal means to harvest California 's extensive crops . </P>
