Agro-ecology & Sadri Dem-Siah identity
Sadri Dem-Siah (Oryza sativa L.) is a luxury native rice of northern Iran; its optimal ecotype sits in the Sefidrood delta lowlands of Astaneh Ashrafieh County. Fresh river water, loamy–clay soil and coastal humidity boost 2-acetyl-1-pyrroline and uniform starch in the endosperm.
Dark pigment and long black awns on golden paddy define the name. Raw kernels are 7–7.5 mm with a dense “bone” texture; cooked length reaches 12–16 mm with exceptional softness retention. Low field yield and lodging risk tighten supply and widen the premium price gap.

Market structure & risks
A three-tier network spans village mills (Lesko Kolaye, Kisam), mid-tier sorting complexes and urban brokers on Sardar Jangal and Beheshti streets; the county guild sets conversion fees and discipline.
Key risk: bulk blending — NIR inspection, genetic certificates and sealed traceable packs are required.
Contract farming (e.g. Gildeh cooperative) and premium buy-back are vital to keep Dem-Siah in the field.
Export outlook
Persian Gulf, Central Asia and EU diaspora channels match Basmati-like cooking behaviour. PGI registration for “Astaneh Ashrafieh Gilan Dem-Siah rice”, international MRL compliance and MAP packing in Nogreh Deh anchor sustainable value capture.
