Or S. elaeagnifolium?
Yellow fruits on ground...field had been cut
Around 1-1.5 feet tall.
Solanaceae -- thanks to Stig Madsen for ID help. He thought the thorns might be too thin, which is why I've put it in ID Please, but I've been thru all the NJ Solanum sp., & this is the only one even close. Growing in an abandoned railyard -- perfect match on habitat. Fruits are 1–2 cm across.
