The offerings include pottery with sprouted Barley (Hordeum vulgare), a decorated coconut (Cocos nucifera) and flowers of several plants. 

Sprouting barley has also been documented in Calcutta (november 2014), where it is offered for sale as germinated grain and as seedlings in pottery, similar to the one on the photo.

I am asking this question on behalf of the author of the photograph, René Cappers. He is currently preparing a book on traditional agriculture practices and food preparation.

With kind regards and thanks in advance for your help,

Roelf Barkhuis
