Stubble (parali) burning is a method of removing paddy crop residues from the field to sow wheat from the last week of September to November, coinciding with the withdrawal of southwest monsoon.
Stubble burning is a process of setting on fire the straw stubble, left after the harvesting of grains, like paddy, wheat, etc. It is usually required in areas that use the combined harvesting method which leaves crop residue behind.

What caused the Reduction in Stubble Burning?
State governments went for both in-situ and ex-situ management and a special campaign was started to honour the farmers who did not burn stubble.
---In-Situ Treatment of Stubble: For example, crop residue management by zero-tiller machine and Use of bio-decomposers (e.g., Pusa bio-decomposer).
---Ex-Situ (off-site) Treatment: For example, Use of rice straw as cattle fodder.

Effects of Stubble Burning:
-Soil Fertility
-Heat Penetration
