Final answer:
Sugarcane is propagated using vegetative propagation, an asexual reproduction method that ensures genetic uniformity and allows for fast, efficient crop production.
Step-by-step explanation:
Sugarcane is planted by cutting into pieces in a type of asexual reproduction known as vegetative propagation. This method is applied for two main reasons.
First, it ensures genetic uniformity, as each new sugarcane plant is genetically identical to the parent plant, guaranteeing the consistency of crop characteristics such as sweetness, growth rate, and disease resistance.
Second, vegetative propagation is a fast and efficient means of reproduction that allows large-scale production of sugarcane without the need for seeds, facilitating rapid establishment and growth of the crop.
