The given table illustrates the changes in the production of four different types of over a period of five years, from 2010 to 2015, with predictions until the year of 2030.
Overall, it is evident that an upward trend was observed in all types of grains, with the production of wheat remained the leading grain crop throughout the entire period.
Taking a closer look at the chart, wheat production increased by 5 million metric tons after five years and was predicted to continue growing steadily before hitting 110 million metric tons at the end of the period. The production of barley, despite starting at only 50 million metric tons, which was only halved of that of wheat in 2010, experienced a dramatic growth to 70 million metric tons in 2015 and was projected to expand by 10 million metric tons after each five-year-period before ending at 100 million metric tons in 2030.
The figure for maize crop was only about a third of wheat crop at the start of the period, and was predicted to remain virtually unchanged until 2030. The production of rice witnessed a small downfall from 24.7 to 24.3 million metric tons in 2015, but was anticipated to increase slightly over the next fifteen years, ending at an estimated 25.5 million metric tons at the end of the reported period.
