In the last post I compared potatoes watered by olla vs hand-watering. I found that I got similar yields, but higher efficiency using ollas (pounds/seed).
How does using ollas compare to my control plot in 2010? Check it out:
Olla Bed: 16.75#, 1.4 #/seed
Control Bed: 10.7#, 0.6 #/seed
So. Compared to my other option for growing potatoes out by the street (no water), using ollas increased my yield by 60% and was more than twice as efficient!
Qualitatively, the potatoes from the olla bed (half russetts and half red sangre) were a mix of sizes distributed from large to small. In contrast, the control bed (mostly red sangre, the better producer) produced mostly small potatoes, with only a few medium-sized (photo above).
Conclusion? Ollas rock. Compared to not watering at all, they produced more and larger potatoes more efficiently. Compared to hand-watering, ollas increased potato production efficiency.
Here is the control bed in photos (compare with olla bed).
