Potatoes by Olla or Not – Here is the Answer!


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).

We dug the potatoes in the control bed on August 30 after the fronds had all died back.
