Question

Sathiyavarsha K · Answer

From your image, the 32-day-old paddy seedlings are showing signs of yellowing and drying from the leaf tips, which is commonly due to one or more of the following issues:

Likely Problem Diagnosis:
Nutrient Deficiency (Especially Nitrogen or Potassium)

Yellowing of older leaves and poor tillering is a classic symptom of Nitrogen deficiency.

Potassium deficiency can cause drying or burning of leaf tips.

Root Damage or Poor Root Development

Due to stagnant water or iron toxicity, roots may not grow well, affecting nutrient uptake.

Algal Growth & Anaerobic Conditions

The presence of algae or scum (visible in your water) reduces oxygen for roots, hampering growth.

Tungro Virus / Bacterial Leaf Blight (BLB) (less likely here)

These usually cause yellowing with stunting or lesions, but your image doesn’t strongly suggest this yet.

Recommended Treatment:
1. Nutrient Application:
Urea (Nitrogen):

Apply 35–40 kg urea per acre as a top dressing immediately.

MOP (Muriate of Potash):

Apply 15–20 kg per acre if not applied earlier.

Zinc Sulphate (21%):

Mix 5 kg per acre in 200 liters of water and spray. Use if plants are yellowing with weak growth.

2. Improve Water Management:
Drain excess water for 1–2 days to let the soil breathe.

Avoid continuously stagnant water at this early stage.

3. Control Algae:
Apply 5 kg copper sulfate per acre, dissolved in water, over standing water.

This will suppress algal growth and improve oxygen flow to roots.

Monitor:
If yellowing continues or leaf tips start drying rapidly with stunted growth, consider checking for BLB or Tungro and use appropriate fungicides or antibiotics.
