With reference to the transplantation of seedlings, consider the following statements: 1. Seeds of paddy are first grown in a nursery. 2. When seedlings grow, they are transplanted to the field exclusively by automated machines. 3. This method is commonly used for crops like paddy and chillies. Which of the statements given above is/are correct?

Correct Option The correct option is (c) 1 and 3 only. Explanation Transplantation is an agricultural technique where seeds are first sown in a nursery to germinate and develop into young plants (seedlings). Once they reach a specific growth stage, healthy seedlings are selected and replanted in the main cultivation field. Statement-wise Analysis - Statement 1 is Correct: Paddy (rice) is a classic example of a crop grown via transplantation. Seeds are first grown in a nursery bed to ensure proper germination and early development before being moved to the flooded main field. - Statement 2 is Incorrect: The statement claims that transplantation is done exclusively by automated machines. This is factually wrong. While mechanical transplanters are used in mechanized farming, manual transplantation by hand remains a predominant practice in many agricultural regions, particularly in India. - Statement 3 is Correct: Transplantation is a standard practice for several crops beyond paddy, including chillies, tomatoes, and brinjal (eggplant). This method allows for better root penetration, spacing, and the elimination of unhealthy seedlings. Key Takeaway: Transplantation allows farmers to select healthy seedlings and ensures better crop establishment. It is applied to crops like paddy and vegetables (chillies, tomatoes) and can be performed either manually or mechanically.
