Devevelopment and Adoption of Annual Strawberry Production in the Great Plains

Development and Adoption of Annual

Strawberry Production in the Great PlainsC.L. Rivard, K. Oxley, M. Taylor, M. Kennelly, D. Pryor, and M. Bates

Jerry WohletzLawrence, KS

Project ObjectivesIncreasing the regional production distribution

• To verify the utility of annual plasticultureproduction and deliver crop budgets to growers.

• To determine the optimum application timing and thickness of row covers for open-field production.

• To determine how row covers affect the soil and canopy microclimate in the open-field.

• To investigate the utility of spring-planted, day-neutral production in high tunnels.

• To determine how evaporative cooling affects crop performance and disease incidence (pre- and post-harvest) for high tunnel strawberry production.

• To disseminate crop production information to growers in the Great Plains.

Trial Description: The trial will be made up of 48 plots (10’ length) anddesigned in split-plot design with four replications. Main plottreatments are with and without evaporative cooling and sub-plots arethe varieties. The trial will be located on four rows in a three seasonhigh tunnel with 30% shade cloth.
