Is what the weather trouble

Question

Sathiyavarsha K · Answer

Yes, weather can definitely be the cause of the problem (such as poor growth, yellowing, or small potato size).

How weather affects potato size and growth

Low temperature (too cold)

Plant growth becomes slow

Tuber bulking (potato size increase) is reduced

High temperature (too hot)

Leaves turn yellow early

Tuber formation and bulking stop

Excess rainfall / waterlogging

Roots get damaged

Tuber rot and diseases increase

Moisture stress (lack of water)

Poor tuber development

Small-sized potatoes

What you should do to reduce weather stress

Maintain light but regular irrigation, especially at 60–80 days after planting

Apply potassium (SOP) to support tuber bulking

Avoid spraying chemicals during extreme heat or cold

Ensure proper drainage; do not allow water to stand in the field

Ideal weather for potato bulking

Temperature: 18–25°C (day) and 12–18°C (night)

Cool nights and moderate days give the best potato size
