Washington's agricultural industry may be better known for the apples, carrots, hops, or wines produced here; however, the small-seeded vegetable seed grown in this state is the foundation for a major share of vegetable production in the United States and worldwide. Washington is known to produce high-quality vegetable seed: an essential ingredient in any crop equation. Without quality seed, no matter how much time growers spend preparing the land and controlling pests, they cannot produce prime crops. Washington's vegetable seed also commands a large share of some seed markets. Seventy percent or more of all the nation's carrot, spinach, radish, and beet seed is produced here. These same crops account for approximately 50% of worldwide seed production.
