grandymaker [24]

Answer: Bengal gram is a leguminous plant.

Explanation:

Legumes are the plants that can fix nitrogen by symbiotic mutualistic association with the soil bacteria. The bacteria converts atmospheric nitrogen into plant usable for like ammonia and derives nutrition from the plant in return. This association results in the formation of root nodule for uptake of nitrogen derivatives from the soil and return of nutrients to bacteria. Bengal gram is a leguminous plant so it can avail nitrogen with symbiotic association with the bacteria in the soil. Although nitrogen is not given in the fertilizer but the gram crops can sustain themselves by obtaining nitrogen from the soil in association with nitrogen fixing bacteria.
