WebThe measure of growth used in Fig. 1.2 is relative growth rate (R), a concept introduced to describe the initial phase of growth of annual crops (Blackman, 1919; Hunt, 1982). Use of R assumes that increase in dry weight with time ( t ) is simply related to biomass ( W ) and, therefore, like compound interest, exponential (i.e. the heavier the plant, the greater will be … WebOct 5, 2024 · Calculate the growth rate formula.
