The data from my growing pull sprouts vs tubers last year. This worked well for long season potatoes. Short season potatoes seem to go into early senescence doing this and had low yield. Not worth bothering doing this for short season potatoes.

I tracked this with 3 potato varieties last year.
Average Yield From Tubers From Pull Sprouts
Purple Peruvian 17.2 oz 11.1 oz
CIP396286-7 15.1 oz 15.35 oz
Satina (early-mid variety) 9.2oz 9.0 oz

Even if yields end up being slightly lower, this is an easy way to multiply tubers into far more plants.

I also did this with Finn Bad, an early potato, and it produced very little from pull sprouts (3.1 oz)

As you mention Nathan this is an easy way to multiply tubers into far more plants.

One planted potato tuber may yield 2 pounds with multiple "eyes" emerging as one cluster but you can get 4-6 "pulls plants" from a single tuber and each yields 1 pound is about 6 pounds from just one tuber as seed. A great way to multiply plants and not have to save so many potatoes as seeds.

Another thing I noticed is that varieties that were grown from pull plants tend to be bigger in size but when I plant tubers it tend to send out 2-3 shoots I get smaller potatoes but more numerous.

My potatos are doing great. All TPS Pull starts and tubers. Some pull starts stayed micro did not grow others did great. Some TPS also remained tiny. But mostly ding great.

Is there a thing where you can only should do pull starts with late season Potatoes but not with early's?

Thanks for any answer.

Yes, it is best done with long season potatoes. The process seems to trigger senescence and tuberization earlier than if left connected to the mother tuber. For a short season potato, that often leads to the plant dying back after a short amount of time, with only small tubers. They stop growing too early.

I have tried it with several 70-80 day potatoes and found they die back after 30-40 days.

Nathan

I have one other question.

What is you choice for your growing medium for pull starts.

I mean where we put the tubers for sprouts.

Is dampened Peat ok? Temperature?

Thank You
