Rhizobia form nodule in Glycine max (Soybean) is
1 Azorhizobium
2 Bradyrhizobium
3 Sinorhizobium
4 Mesorhizobium
Explanation:
Soybean (Glycine max) is one of the important legume crops. It forms symbiotic association with nitrogen fixing rhizobia. In this association soybean can be nodulated by rhizobial genera Bradyrhizobium.

Which is the most efficient free nitrogen fixer cyanobacterium in field of rice?
1 Nostoc
2 Tolypothrix
3 Aulosira
4 Anabaena
Explanation:
Cyanobacteria like Nostoc, Anabaena, Aulosira are the most common nitrogen fixing organisms, probably with the help of heterocysts. In the rice fields, Aulosira is most efficient nitrogen fixing cyanobacteria.

A free living nitrogen fixing blue-green algae which also form a symbiotic association with a pteridophyte
1 Anabaena
2 Chlorella
3 Nostoc
4 Tolypothrix
Explanation:
The free-living nitrogen fixing blue green algae that also forms a symbiotic association with a pteridophyte is Anabaena. Anabaena is known for its ability to fix nitrogen under a wide range of conditions. It is a valuable bio-fertilizer for crops such as rice. Anabaena forms symbiotic association with the water fern Azolla (a pteridophytes)

Gas being produced by paddy fields and involved in global warming is
1 $\mathrm{CO}_2$
2 Chlorine
3 Methane
4 $\mathrm{H}_2 \mathrm{~S}$
Explanation:
Methane is the one of the green house gases responsible for global warming, emitted from flooded rice fields as bacteria in the waterlogged soil produce it in large quantities.
