Detailed explanation-1: -Many factors influence the optimum plant population for a crop: availability of water, nutrients and sunlight; length of growing season; potential plant size; and the plant’s capacity to change its form in response to varying environmental conditions (morphological plasticity).
Detailed explanation-2: -The higher the planting density, the smaller the space between plants. This results in longer, thinner, smaller and yellowing of leaves of the sprouts. In addition, high planting density inhibits photosynthesis resulting in rotting of seedlings and lower yield.
Detailed explanation-3: -There are three components of change: births, deaths, and migration. The change in the population from births and deaths is often combined and referred to as natural increase or natural change. Populations grow or shrink depending on if they gain people faster than they lose them.
