The supplied table demonstrates the number(million metric tones) of the data about the manufacture of grains(wheat, barley, maize and rice) between 2010 and 2030.
Overall, at the beginning of the period the most production was in the wheat. However, rice contributed the least of the chart. In comparison, in the final year, wheat again will comprised the biggest part of the production, while rice will be the smallest segment of the table.
In 2010, wheat was 100 MMT and has been increased for each year and will reach to 110 MMT in 2030. Barley accounted for 50 MMT in 2010 and the following 20 years it will be surged by 50 MMT. In 2010, 34 MMT of maize rose to 34.5 MMT in 2015 and remained stable for 5 year-period, after 2020, the number of maize continued to go up and will reach to 35 MMT in 2030. Finally, rice(24.7 MMT) and it has been continuing to surge and will account for 25.5 MMT in the final year.
