• A. Root trainers
• B. Dos
• C. Baskets
• D. Polybags

Hint:

Using leaf cups (dos) in nursery practice is an effective zero-waste, low-cost technique that prevents transplanting shock because the root system is planted undisturbed inside its decomposing container.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
In traditiol forest nurseries, especially in developing regions, biodegradable and locally sourced containers are used to raise seedlings.
These options are environmentally friendly altertives to plastic polybags and can be planted directly into the soil.

Step 2: Detailed Explation:
Let us alyze the terms for nursery containers:
- Dos: These are traditiol cups or bowls made of broad leaves, typically from species like Butea monosperma (Palas) or Shorea robusta (Sal), stitched together with thin twigs.
In rural forestry and nursery magement, dos are used as cheap, eco-friendly, and biodegradable containers to raise young seedlings.
When transplanting, the entire do can be placed directly into the planting pit, where the leaves turally decompose and enrich the soil without disturbing the seedling's root system.
- Root Trainers: Rigid, reusable plastic containers with vertical ribs designed to prevent root coiling and promote vertical root growth.
- Polybags: Synthetic polyethylene bags widely used for raising nursery stock.
- Baskets: Woven containers made of bamboo or cane, larger than individual seedling leaf cups.

Step 3: Fil Answer:
A biodegradable cup made of leaves used in nurseries is known as a do.
Hence, the correct option is (B).
