Bonarota, M-S., Barrios-Masias, F., Moe, J., Kratsch, H. 2025, Nitrogen Fertilization and Grafting of Tomato Under High-Tunnel Production in Northern Nevada, University of Nevada, Reno Extension, IP-25-01

This study evaluated the effects of high and low nitrogen fertilization on grafted and ungrafted tomatoes under high tunnels at three sites in northern Nevada. Yield responses were site-specific and influenced by historical soil conditions at each site prior to nitrogen additions. We found that grafting has the potential to increase tomato crop productivity in northern Nevada by as much as 62%, especially when soil nitrogen availability is not optimal. Farmers using organic methods should time fertilization considering soil temperatures that favor soil microbial decomposition to make sure nitrogen is available during tomato peak demand.
