Concept:Elasticity of supply shows how much the quantity supplied responds to a change in price.
When supply is elastic, a small price rise leads to a large increase in quantity supplied.
Explanation:In the market period, agricultural goods are already produced and perishable, so supply is fixed and highly inelastic.
In the short run, farmers can change only some inputs like seeds or fertiliser, so supply can increase only slightly.
In the long run, all factors of production become variable.
Farmers can buy more land, hire more labour, purchase better equipment, and expand farming activities.
They can also switch from one crop to another in response to price changes.
Therefore, agricultural supply is most elastic in the long run because farmers have enough time to adjust production fully.
