When LAI = 1,

A. RGR = LAD

B. NAR = LAR

C. LAR = LER

D. CGR = NAR

Answer: Option D

Solution(By Examveda Team)

LAI = Leaf Area Index
CGR = Crop Growth Rate
NAR = Net Assimilation Rate
LAR = Leaf Area Ratio
RGR = Relative Growth Rate
When LAI is 1, then Crop growth Rate is the same Net Assimilation Rate. A low leaf area index directly influences the light interception per unit area, affecting CGR and ultimately the NAR.
