Legumes fail to develop nodule as soil having pH of

A. > 5

B. < 5

C. < 5.5

D. None of the above

Answer: Option B

Solution(By Examveda Team)

Legumes fail to develop nodules as the soil has a pH of < 5.
Legumes can form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia.
At low pH (<5), dry matter production, seed yield and nitrogen fixation were significantly lower than at higher pH levels. Low pH delayed the development of nitrogenase activity.
