Detailed explanation-2: -An apparatus called the auxanometer can be used to measure plant growth. Measuring the height of the plant. Checking the size and number of the leaves.

Detailed explanation-3: -Plant growth rate can be measured as the relative increase in leaf area over time, by substituting total plant leaf area for total biomass in the conventional RGR equation.

Detailed explanation-4: -Twenty-one days after sowing (Figure 1), shoot length (SL) (cm), was measured from the soil contact point to the tip of the plant and number of trifoliate leaves was counted. Shoot dry weight (biomass) (g) was recorded after drying the shoots in the glasshouse at room temperature for 72 hours.
