California Pistachio Growers Survey

Surveys were distributed to 300 California pistachio growers, and 110 growers responded (36.7%). The information, summarized here in a series of charts, presents grower practices and concerns with respect to tree nutrition, fertilization, tissue sampling, use of UC critical values, irrigation practice, including fertigation, and future practices.
