Question

____________________________________is not a post-harvest operation for rice

• A. Polishing
• B. Milling
• C. Parboiling
• D. Puddling

Hint:

Puddling is a wet tillage operation performed before transplanting rice seedlings to reduce percolation losses in paddy fields.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Agricultural operations are classified into pre-harvest, harvest, and post-harvest operations based on when they occur in the crop production cycle.
Post-harvest operations occur after the crop has been harvested to prepare the grain for storage, processing, and consumption.
Detailed Explanation:
Let us analyze each of the operations listed:
- Parboiling: A hydrothermal post-harvest treatment applied to paddy before milling. It involves soaking, steaming, and drying the grains to gelatinize starch, which improves milling recovery and nutritional value.
- Milling: A post-harvest processing step where the outer husk and bran layers are removed from the paddy grain to produce edible white rice.
- Polishing: A final post-harvest milling step that rubs the milled rice grains to remove any remaining bran and give them a smooth, glossy appearance.
- Puddling: A pre-planting tillage operation performed in wet paddy fields.
It involves churning the saturated soil with standing water to break down soil aggregates and create an impermeable clay layer, reducing water percolation and controlling weeds before transplanting rice seedlings.
Therefore, puddling is a field preparation step, not a post-harvest operation.

Step 2: Final Answer:
Puddling is not a post-harvest operation for rice.
