Farmer-Led Research Tests High Tunnel Tomato Pruning

Practical Farmers of Iowa has released a Farmer-Led Research report on the impact of pruning tomatoes in high tunnels. Iowa farmers Maja and Carmen Black and Natasha Hegmann were interested in learning the impact of double-leader pruning on tomato yield and labor-time in their high tunnels. In this study, cooperators documented labor for different tasks along with tomato weight and fruit count. They found that although time spent on labor was higher for the pruned tomatoes at the Blacks, at Hegmann’s, time spent on labor was higher for un-pruned tomatoes. Additionally, at the Blacks’ there was no difference in yield, while at Hegmann’s the pruned plants produced larger fruits and the un-pruned plants produced more fruits. The full report is available online.
