RESEARCH REPORT: Tomato in High Tunnel: Variety Trial

Following a 2016 tomato trial on Rebelski and Mountain Fresh Plus, three farms conducted replicated variety trials in their high tunnels on Big Beef, Rebelski, and Big Dena. Key findings are in the post below, and the full report is available here: Tomato in High Tunnel, Variety Trial.

How was the trial conducted?

Each farmer planted two tomato varieties inside a high tunnel in a randomized, paired trial. Farmer-researchers for this trial were: Tim Landgraf (One Step at a Time Gardens in Kanawha), Lee Matteson and Rose Schick (Lee’s Greens in Nevada), and Mark Quee (Scattergood Farm at Scattergood Friends School in West Branch). Spacing, mulch, trellis style, and planting date were determined by farm, and described in Table 2. Plants for the trial were started indoors and transplanted to the high tunnel (in-ground). Matteson and Schick planted into a heated high tunnel.

Findings

Figure 1 shows cumulative yields through the season at each farm. Bold lines represent the varietal average and lighter lines show the individual plot yields. Using repeated measures analysis, average yields for Big Beef were statistically higher during August at Landgraf and Quee, but by the end of the summer, there were no statistical differences in overall yield. At both farms, the earlier-maturing Big Beef showed higher yields early on, with Rebelski catching up toward the end of the season. Statistical analysis was not performed at Matteson/Schick, but total yield for both varieties (Big Beef and Big Dena) at the end of harvest were within two pounds of one another. Similar to the pattern at Landgraf and Quee, Big Beef got off to a faster start, and fruit production from Big Dena eventually caught up in September.
