Question

Biofertilisers give a better yield when added along with ______.

पर्याय

• phosphate fertilisers

• calcium fertiliser

• nitrogen fertilisers

• urea

Answer 1

Biofertilisers give a better yield when added along with phosphate fertilisers.

Explanation:

Optimal phosphorus improves nitrogen fixation by biofertilisers such as Rhizobium, so adding phosphate fertiliser gives a better yield. Nitrogen fertilisers and urea reduce the need for fixation, and calcium fertiliser does not help the fixing process.
