Turmeric is a spice/rhizome crop. Guntur district's official page describes a Duggirala turmeric processing cluster with micro firms making processed turmeric and powder. The agricultural crop and the cluster are linked but not identical: farmers may grow turmeric in several places, while processing concentrates where market and industry conditions favour it. A district fact question may ask for the crop associated with Duggirala, which points to turmeric rather than chilli.

Do not confuse Duggirala the place with Duggirala Gopala Krishnaiah, the freedom-era figure in the preceding personalities volume. The shared name is a classic AP exam distractor. A local value-chain diagram can run from rhizome cultivation to curing, drying, grinding and sale, but the exact processing technique needs a specialist standard. This book tests the district association and the distinction between raw crop and value-added product.

Worked example: Duggirala is associated with turmeric processing. A processing cluster is a place-value-chain clue, not proof that all turmeric sold there was grown nearby. The fresh rhizome, dried product and powdered spice have different weights. A market-price comparison should match product form and date; an exam location match should name the crop and processing link.

Active recall: Pair Duggirala's present processing cluster with its crop and distinguish it from the historical person.
