Explanation
A nursery bed is a specially prepared area where seeds are sown and seedlings are raised under controlled conditions before being transplanted to the main field. The main purpose of a nursery bed is to provide an optimal environment for germination and early growth of seeds, ensuring uniformity, vigor, and healthy development of seedlings before they are planted in the field. This practice allows farmers to manage crop establishment, timing, and spacing effectively, leading to better crop yields and productivity.
