Final answer:
The difference between Rajan and Avinash's farming methods is in the plant reproduction method—conventional farming uses seeds leading to genetic diversity, while vegetative propagation involves cloning parts of plants, ensuring genetic uniformity and ease of management.
Step-by-step explanation:
The difference between Rajan, who grows plants by conventional means, and Avinash, who uses vegetative propagation, primarily lies in the plant reproduction method. Conventional farming typically involves sexual reproduction, where seeds are sown and plants grow from these seeds, leading to genetic diversity among the offspring. This method can be beneficial for crop improvement and the development of new plant varieties but may also result in variability that complicates consistent agricultural practices.
In contrast, vegetative propagation is a form of asexual reproduction where new plants are grown from parts of existing plants, such as stems, roots, or leaves. This method ensures that the new plants are genetically identical to the parent, providing crop uniformity that eases agricultural management through identical cultural practices like planting and harvesting. However, since these plants are clones, they do not contribute to genetic variation, which can be a hindrance in adapting to changing environmental conditions or pest pressures.
Overall, the choice between conventional farming and vegetative propagation affects several aspects, including genetic diversity, ease of farm management, and potentially the ability to select for specific traits in crops.
