It is indeed that perennial favourite, "Dilmano Dilbero", on the tantalizing methods for growing peppers!!

I first learnt this one in the early 80s, from the 1966 recording of The Pennywhistlers : https://www.youtube.com/watch?v=uK-Sw6UvCQI
"Folksongs of Eastern Europe" and it remained in the repertoire through my various a capella ensembles thereafter!!

Fun to sing :)
