-When an immediate supply of a single necessary factor falls below the combined demand of the plant, it is referred to as a limiting factor.
-This can include factors such as water, nutrients, sunlight, or temperature, depending on the specific requirements of the plant species.
-When a limiting factor is present, it can restrict the growth and development of the plant, leading to reduced productivity or even plant mortality. Therefore, it is important for growers to identify and address any limiting factors in their crop management practices to optimize plant growth and yield
-Allelopathy refers to the ability of plants to produce and release chemicals that can affect the growth and development of other nearby plants.
-These chemicals can have either beneficial or detrimental effects, depending on the specific plant species involved and the concentration and duration of exposure.
