Question

Three crops that contribute maximum to global food grain production are:
A. Wheat, rice and maize
B. Rice, maize and sorghum
C. Wheat, maize and sorghum
D. Wheat, rice and barley

Answer 1

Hint:- Global food grain production refers to the total quantity of various food grains produced globally across the world per year. According to the surveys (latest-2016/2017), an approximate of 2.2 billion metric tonnes of grain are produced every year worldwide. The overall world cereal utilization was recorded as 2744 million tonnes for 2020-21.

Complete step-by-step solution:-
Wheat, rice and maize are the three crops that contribute maximum to the global food grain production. These three crops form the base of grain requirement across the world. This is mainly responsible for the high production rates of these food crops across the world. Rice is accepted as the staple crop in most parts of the world. Rice is the major food crop, followed by wheat and maize. Due to the high requirement and demands of the increasing population, the cultivation of these crops are grand for the supply to remain adequate.
According to the datas, the wheat production in 2020 reached the level of approximately 765 million tonnes.
Maize is widely grown throughout the world and holds the record of highest production of all the cereals. The record remains 817 million tonnes from a 2009 survey.
Rice is produced approximately 496 million metric tonnes every year globally.
The correct answer is option (A) Wheat, rice and maize.

Note:-
Grains are annual plants. Thus, per year, the yield is only one crop which is mostly seasonal. It is better if the grain production remains ahead of the demand so as to solve the hunger issues worldwide. Barley, corn and sorghum are also among the top grains produced.
