Question

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

Answer 1

Hint: A rice transplanter is a specific transplanter fitted to relocate rice seedlings onto a paddy field. Mostly two kinds of rice transplanter i.e., riding type and strolling type. The riding type is power-driven and can typically relocate six lines in a single pass. Then again, the strolling type is physically determined and can, as a rule, relocate four lines in a single pass.

Complete answer:
India is one of the world's biggest makers of rice, including white rice and earthy colored rice, filled generally in the eastern and southern pieces of the nation. The Production expanded from $53.6$ million tons to $74.6$ million tons in a span of 10 years, a 39 percent expansion throughout the decade. Since 1950 the expansion has been more than 350 percent. The majority of this expansion was the aftereffect of an increment in yields; the number of hectares didn't increase during this period. The per-hectare yield expanded more than 262 percent somewhere in the range of 1950 and 1992.
Even though rice is filled in territories other than Asia, rice transplanters are utilized primarily in East, Southeast, and South Asia. This is because rice can be developed without relocating, by essentially planting seeds on the field, and ranchers outside Asia favor this complain free path to the detriment of decreased yield.
Points of interest of relocating:
The plant populace turns out to be more guaranteed.
Since nurseries possess just $1/10$ of the zone of the primary yield, the water system, sicknesses, and other administrations become simpler to diminish the expense of raising seedlings when contrasted with a transmission wet harvest of a similar age. Nurseries brought up ahead of time, empower the yield to be planted in the field at the correct time.
The seedlings are grown up at the hour of relocating and they can contend with youthful weeds that spring up. Weed control and other social activities are a lot simpler, especially in line planting.

Thus, option (B) is correct.

Note: Rice is one of the main grains of India. Additionally, this nation has the biggest territory under rice development, as it is one of the key food crops. It is indeed the prevailing yield of the nation. India has been identified as one of the main makers of this harvest.
