Crops are larger and able to produce more grain per acre

Explanation:

The high-yield crops have been used more and more in the past several decades. The reason for that is simple, they produce larger crops that produce more grain per acre. This is very beneficial for the farmers, as they get more profit from the same farmland. But more importantly, this is very beneficial because the problem with malnutrition is lowered, as there is much more food on the market for available prices.
