Barley, Producer Price
FAO publishes this commodity's food-balance elements in two domains with different methodologies (historic 1961-2013 vs current 2010-2023); they disagree materially where they overlap, so both are kept as separate labelled series rather than spliced.

Laws related to this measure. Correlation = how closely this law tracks this measure's story. Expected causation = how strongly we would expect it to have moved the line. Neither is a claim of proof.
1989CorrelationExpected causationAct Amending the Guaranteed Purchase of Essential Agricultural Products Act of 1989
Passed in 1993, this law extends the list of staple crops covered by the 1989 Guaranteed Purchase Act to include raisins, dates, dried fruit, citrus, apples, pomegranates, figs, livestock products and silk cocoons.
Why this link: The same guaranteed-purchase-price framework also covers barley and other cereal staples, giving the amendment a broader reach across essential cereal prices beyond wheat.
Caveat: Barley and other cereal prices are less consistently or fully covered by guaranteed purchase in practice than wheat, so attribution is weaker for these commodities.
1989CorrelationExpected causationGuaranteed Purchase of Essential Agricultural Products Act
Passed in 1989, this law requires the government to guarantee and announce a minimum purchase price each farming year for staple agricultural products such as wheat, rice, barley, cotton and oilseeds, later extended to raisins, dates, citrus and livestock products, in order to support farm incomes and stabilize production.
Why this link: Barley and rice are among the other basic crops that have at times fallen under guaranteed-purchase-price coverage, giving this law an indirect but real channel to their price series.
Caveat: Coverage and enforcement of guaranteed prices for these crops has varied by year and is harder to isolate from broader market and weather effects than for wheat.
Lag: Annual.2005CorrelationExpected causationAct Adding Two Notes to the Guaranteed Purchase of Essential Agricultural Products Act of 1989
Passed in 2005, this law amends the 1989 Guaranteed Purchase of Essential Agricultural Products Act by requiring the government to raise the guaranteed purchase price of staple crops each farming year by at least the rate of inflation reported by the Central Bank, applied retroactively to the 2004-2005 crop year.
Why this link: The guaranteed-purchase-price regime this law amends covers all 'basic' agricultural crops, not just wheat, so it shapes producer prices across the guaranteed-purchase basket.
Caveat: Coverage and the specific crops included in the guaranteed-purchase list vary by year and are set by separate annual government decisions, so the link to any single crop's price series is indirect.

Issued in 2012, this bylaw sets the rules for trading guaranteed-price agricultural products on Iran's commodity exchange, defining the guaranteed price as the minimum producer payment set by the cabinet, and has the government cover the gap between the exchange price and the guaranteed price for approved crops.
Why this link: Wheat and barley are the flagship crops covered by Iran's guaranteed-purchase-price system that this bylaw operationalizes, giving it a real but partial channel into observed farm-gate prices.
Caveat: Farm-gate prices also reflect input costs, exchange-rate pass-through and global grain prices, which typically dominate the guaranteed floor's effect.
