A green manure is:
1 Sesbania
2 Wheat
3 Maize
4 Rice
Explanation:
Green manures are fast growing herbaceous crops which are ploughed down and mixed with the soil while still green for enrichment of soil. For exampleSesbania sesban (Dhaincha), Crotalaria juncea (Sunnhemp), Barseem etc. are belongs to the family leguminosae.

The yielding of rice is increased by
1 Azolla
2 Nostoc
3 Anabaena
4 Clostridium
Explanation:
Azolla is an aquatic fern, coexist with rice plants. It forms symbiotic association with nitrogen fixing bacteria known as Anabaena. This association is used as a biofertilizer to enhance rice yield.
