Which one is the recommended optimum plant population for maize

Solution (By Examveda Team)

The optimum density or plant population for any field or cultivation results in mature plants that are sufficiently crowded to efficiently use resources such as water, nutrients, and sunlight, at the same time not so crowded that some plants die.
For an optimum yield of maize, a population of 65 - 70 thousand plants should be there per hectare.
