  Frequently Asked Questions

  What is Integrated Nutrient Management (INM)?

  INM is an agricultural practice that combines chemical fertilizers with organic manures (like FYM or vermicompost) and micronutrients to optimize crop yield and soil health.

  How does INM affect the yield of late-sown mustard?

  The study shows that applying 100% NPK along with Sulphur, Boron, and Zinc can increase seed yield by up to 25.32% compared to using standard NPK alone.

  Which nutrients are most critical for mustard growth in Punjab?

  In addition to Nitrogen, Phosphorus, and Potassium (NPK), the addition of Sulphur (S), Boron (B), and Zinc (Zn) significantly improves growth parameters and siliqua development.

  What are the economic benefits of using integrated nutrients?

  Treatments combining 75% RDF with FYM or vermicompost recorded the highest net returns and a better Benefit-Cost (B:C) ratio compared to chemical-only treatments.

  How does nutrient management impact soil properties?

  Integrated management improves the physico-chemical properties of the soil, including organic carbon content and the availability of essential macro and micronutrients for future crops.
