Effect of Plastic Mulch Color on Tomato Production in High Tunnels

High tunnel production is increasing in Iowa as they provide protection from wind and frost and help extend the growing season. Although production aspects inside high tunnels are similar to field production, high tunnel environment is challenging especially when it comes to temperature management. During summer, temperatures rise fairly quickly in high tunnels and can detrimentally affect crop growth and development. It is not uncommon to see temperatures above 100 degrees F inside high tunnels.
