We actually conducted a trial last year with 10 different paste/sauce varieties. All in raised beds, 7-8 hours of sun, 6’ trellises, and a constant supply of water via ollas. It was not a perfect growing year because of the overly wet weather, and we had space for only one plant of each variety.
Here’s the total harvestable weight we measured per plant in order from best to worst: Mortgage Lifter VFN - 11.5 lbs, Blue Beech - 10.8 lbs, Amish Paste - 9.8 lbs, Dester - 9.1 lbs, San Marzano Redorta - 8.3 lbs, Opalka - 6.6 lbs, Rocky - 6.1 lbs, Long Tom - 5.1 lbs, Federle - 2.5 lbs, San Marzano 2 - not much.
Mortgage Lifter VFN, Amish Paste and Dester were very productive early. The other varieties hit peak production about two weeks later. We’re going to trial the top five again this year but I think Mortgage Lifter VFN and Amish Paste have the inside track with their early production. Blue Beech produced very high quality tomatoes which may keep it around as well. Dester was productive but the tomatoes tend to crack quite a bit.
As far as cherry tomatoes go, Mexico Midget has been the most productive and best tasting. Sweetie was our go to for years and productive as well, but we would lose a much higher percentage to splitting.
