Field Management Tips

Soil Preparation

Prepare well-levelled land with proper drainage before transplanting.

Irrigation

Maintain shallow water during early growth stage and avoid water stress.

Fertilizer

Use balanced NPK along with Zinc and Gypsum for better seed quality.

Pest Management

Inspect the field weekly and control insects and diseases immediately.

Important Note

Always adjust nitrogen fertilizer according to crop condition, soil fertility and weather. Excess nitrogen increases lodging and disease incidence.
