This study tested grafted vs. ungrafted tomatoes under high tunnels at three northern Nevada sites using high and low nitrogen levels. Grafting improved yield up to 62% where soil nitrogen was low. Organic growers should align nitrogen applications with warm soil conditions to support microbial nutrient release.
