Seeds and the Success of Valley Agriculture
While Visalia is best known for citrus, dairy, and tree nuts, seeds are the foundation of much of the region's agriculture. Dairies depend on silage corn, alfalfa, and forage grains to feed their herds. Vegetable growers plant tomatoes, melons, peppers, onions, and leafy greens. Home gardeners and community gardens around Visalia also rely on quality seed for backyard harvests.
The San Joaquin Valley's hot summers, limited rainfall, and variable water availability make variety selection especially important. Seeds bred for heat tolerance, disease resistance, and water efficiency can make a significant difference in yield and profitability. Leading seed companies invest heavily in research and local trials to deliver varieties suited to Central Valley conditions.
