Which of the following statements regarding biostimulants is/are correct?
- They are substances or microorganisms that enhance plant growth by stimulating natural processes like nutrient absorption and stress tolerance.
- According to the Fertiliser Control Order (1985), biostimulants include pesticides and plant growth regulators.
- They can improve grain filling in crops like corn and enhance postharvest fruit quality.
- Biostimulants are exclusively derived from synthetic chemicals and do not include natural sources like seaweed or plant waste.
Select the correct answer using the code given below
Explanation – Biostimulants enhance plant growth by improving stress tolerance, nutrient absorption, or yield. According to the Fertiliser Control Order (1985), they do not include pesticides or plant growth regulators. Biostimulants can be naturally derived, including from plant waste and seaweed, and are not limited to synthetic chemicals. Their benefits include improved grain fill (e.g. in corn) and postharvest fruit quality.
