Q921
Legumes fail to develop nodule as soil having pH of
A.
> 5
B.
< 5
AnswerC.
< 5.5
D.
None of the above
Answer: Option B
Solution
Answer: Option B
Solution:
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.
