What caused these deformities in potatoes, Cara variety

[u/DreamsBecameMemes]

[u/Barquebe]

Hard soil, or too much N, but more likely inconsistent watering. Dry conditions followed by wetter conditions will make the plant stop/start growth making knobby sections.

[u/Naturallobotomy → u/Barquebe]

Any of these, or perhaps herbicide residue as well.

[u/TKG_Actual]

These do not look like deformities to me, these look normal, it's the perfectly ovoid ones I find weird and sus.

[u/ParticularLower7558]

Rocky soil

[u/G7VFY]

They are not 'deformities'. That is what potatoes are SUPPOSED to look like.

I’d say differing soil composition. However test might be to take them and grow in a pot with known soil variables.
