Seed tuber rate for potato is
A. 5 - 10 quintals/hectare
B. 10 - 15 quintals/hectare
C. 20 - 25 quintals/hectare
D. 25 - 30 quintals/hectare
Answer: Option C
Solution (By Examveda Team)
Seed tuber rate refers to the amount of potato seed (in the form of tubers) required to plant one hectare of land.1 quintal equals 100 kilograms, so this rate defines the total weight of seed tubers needed for proper planting.
The recommended seed rate for potatoes varies depending on variety, tuber size, spacing, and intended yield.
20–25 quintals per hectare is the most commonly recommended and agronomically efficient rate for standard varieties and average tuber size.
This rate ensures optimum plant population without seed wastage, promoting healthy growth and good yields.
Rates lower than this (like 5–15 quintals) may lead to poor stand and low yield, while higher rates (like 25–30 quintals) may be excessive and uneconomical unless used for very small tubers or specific conditions.
Therefore, the correct and widely recommended seed tuber rate is Option C: 20 – 25 quintals/hectare.

The seed tuber rate for potatoes is generally between 2.0 to 2.5 tonnes per hectare. However, this can vary depending on the variety and size of the seed tubers. For smaller tubers (30-40g), a seed rate of 2.0-2.5 tonnes per hectare may be sufficient. Larger tubers (45-60mm) might require a rate of 2.0 to 2.5 tonnes per hectare.
So, Right Option is: C
