Plant growth analysis refers to a set of concepts and equations by which changes in size of plants over time can be summarised and dissected in component variables. It is often applied in the analysis of growth of individual plants, but can also be used in a situation where crop growth is followed over time.
American Forests, for example, uses a formula to calculate Big Tree Points as part of their Big Tree Program [3] that awards a tree 1 point for each foot of height, 1 point for each inch (2.54 cm) of girth, and ¼ point for each foot of crown spread. The tree whose point total is the highest for that species is crowned as the champion in their ...

At the end of each day, the plant is observed to have grown by 1 / 2 of the previous day's growth. A club-rush grew 1 unit on its first day. At the end of each day, the plant has grown by 2 times as much as the previous day's growth. Find the time [in fractional days] that the club-rush becomes as tall as the bulrush.
