Does magnetism affect the growth of plants?

How does crowding in plants affect the growth rate?

• I know that plants compete with each other for light, water and nutrients, but how does crowding affect the growth rate? Would i be right in saying that if i could give the plants the necessary amount of water & nutrients a week, that all they would compete for is the light, and thus may increase the height growth rate because the plants are trying to outgrow each other to get to full sun exposure?

• Answer:

  Yes that is correct (but consider shade tolerant plants and other factors that limit growth like CO2 or rooting depth for nutrient uptake and support). Also the plants may allocate more resources into stems and less into belowground growth (roots) or reproductive effort.
