Question

Farmers do not apply nitrogenous fertilizers in the cultivation of pulses plants because
pulses plants already have stored much nitrogenous compounds
pulses do not need compounds of nitrogen because they are autotrophs.
pulses plants fulfil their needs by saprotrophic nutrition
pulses plants derive nutrition from the symbiotic association

Answer 1

please mark me brainlist

Explanation:

do not apply nitrogenous fertilizers during cultivation because these crops have "rhizobium bacteria". These types of bacteria are always available inside the root cells of leguminous plants and it also fixes nitrogen gas present in the atmosphere and supplies it to the plant as ammonia.

Answer 2

Answer:

pulses plants derive nutrition from the symbiotic association with the Nitrogen fixing bacteria like rhizobium. Where the plant provides food i.e., sugar to bacteria and bacteria enrich the soil by Nitrogen by Nitrogen fixation. Thus nodule also get formed.
