Question

What is the main advantage of the transplantation method in rice cultivation?
A. This method ensures maximum utilization of land.
B. It is helpful in achieving an economical use of water and a higher yield.
C. It helps in early harvesting.
D. The draining of water from the field before harvesting is made easy.

Answer 1

Hint: Transplantation is the most common and elaborate rice planting method in Asia. Rice seedlings grown in the nursery are pulled into paddy fields and flatlands and transplanted 15 to 40 days after sowing. Rice seedlings can be transplanted manually or mechanically. It is done to increase yields and reduce weeds.

Complete answer:
The precise spacing between transplanted plants allows them to mature evenly without competing with other plants such as direct seeding. As a result, there is a marked increase in the export quality of transplanted seeds. As many countries seek to address changing weather patterns and agriculture's resilience to those effects, transplantation offers a solution. Then, when the plants are transplanted in the field, they will grow stronger than those sown in the field because of their strong roots. Transplantation minimizes inputs. Effective irrigation minimizes water wastage during early stages of plant growth pest management removes excessive pesticides. Transplant minimizes weed pressure by reducing the amount of time the plant stays on the ground. Transplantation reduces the need for a general workforce. It minimizes weed problems, and maintenance related to transplantation eliminates the need for practices such as crop thinning. Transplanting saves significant seed costs. While all the above features of the transplantation method are advantages, the main advantage is it facilitates high yields while remaining economical.

Therefore, the correct answer is ‘Option (B), It is helpful in achieving an economical use of water and a highest yield’.

Note: Rice can also be manually transplanted. Manual replacements do not require expensive equipment and are very suitable for high-density areas and small rice fields. Seedlings raised in a wet, dry environment, or proper nursery management will produce healthy and strong seedlings.
