Heaviest sweet potato

The heaviest sweet potato (Ipomoea batatas) weighed 43.2 kg (95 lb 3.8 oz) and was grown by Beni Meier (Switzerland) as ratified at the GPC Swiss Pumpkin Weighing Championship in Jona, St Gallen, Switzerland, on 4 October 2025.

This surpassed a record unbroken for more than two decades: a 37-kg (81-lb 9-oz) sweet potato grown by Manuel Pérez Pérez (Spain) in Güime, Lanzarote, Spain, that was verified on 8 March 2004.

By comparison, a large sweet potato found at the grocery store weighs in around 200 g (7 oz), making this monster specimen more than 200 times bigger.

This isn't Meier's first world record for growing giant vegetables: on 12 October 2014, he claimed the title for the heaviest pumpkin after presenting a 1,054-kg (2,323-lb) gourd in Ludwigsburg, Baden-Württemberg, Germany.
