Solution

Farmers who cultivate pulse crops like green gram, Bengal gram, black gram, etc. 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.
