Answer 1

Answer:

Hey mate

Nitrogen is an essential nutrient for plant growth. But farmers who cultivate pulse crops like green gram, bengal gram, black gram, etc. do not apply nitrogenous fertilisers during cultivation. It is because some amount of nitrogen is also present in the soil that help the plants grow.

hope it helps

Answer 2

Answer:

nitrogen is an essential nutrient for plant but farmers grow pulses crop instead of using nitrogenous fertilisers because the nodules of pulses crop contain rhizobium bacteria that convert atmospheric nitrogen into nitrates and work as fertilisers.

fertilisers are harmful and cause water and soil pollution that's why farmers prefer to grow pulses crop instead of using fertilisers.
