Question

WHY DO FARMER WHO CULTIVATE PULSE DO NAT APPLY NITROGENOUS FERTIZERS DURINGS CULTIVATE

Answer 1

The farmers who grow pulses in their fields don't use nitrogen fertilisers because the pulses themselves liberate nitrogen into the soil

Answer 2

Pulses are leguminous plants, i.e, they do not need nitrites and nitrates from outside as they share a symbiotic relationship with rhizobium bacteria which fixes atmospheric nitrogen for it.
