I grew about 10+paste varieties, 400 plants last year in a field with minimal watering and care. Without checking my notes, I grew S Marzano's -redorta a; Roma VF; Romeo, Oroma, and a whole bunch of others.
Most of them performed really well. The best performers are actually a hybrid called Mariana F1. Roma VF (100 plants) was close, a typical plant would have 5 branches, loaded with fruit. Rio Grande was great too.
The best performers also happen to be grown through landscaping fabric, what a huge difference it made in terms of weed control, water preservation, and soil temperature raising early in the season. So it could be just the use of the fabric that made all the difference, now I'm starting to realize it.
