In Jainism, the consumption of corn (maize) is generally avoided during Paryushan (also spelled as Parv or Parva), which is one of the most significant and sacred festivals for Jains. During Paryushan, Jains observe stricter dietary restrictions to practice greater non-violence (ahimsa), self-control, and spiritual upliftment.

Reasons corn is avoided during Paryushan:

• High possibility of life forms: Corn is considered to have more life forms (jeev) and may attract tiny insects or organisms, especially when stored.
• Fermentation: Corn can ferment quickly, increasing the risk of consuming micro-organisms.
• Traditional practice: Jain tradition and community guidelines advise refraining from eating certain foods during Paryushan, including green vegetables, root vegetables, and grains like corn.

Conclusion: Corn should not be consumed during Paryushan. Jains are encouraged to follow the traditional dietary guidelines during this auspicious period to uphold the principle of non-violence and spiritual discipline. For specific questions regarding food during Jain festivals, it is always best to consult your local Jain community or spiritual leader.
