Question

Why are pulses grown in rotation with other groups?​

Answer 1

Explanation:

Being leguminous crops, they help in restoring soil fertility by utilising nitrogen from the air (nitrogen fixation). Therefore, pulses are mostly grown in rotation with other crops. They need less moisture and survive even in dry conditions

Answer 2

Answer:

this is because they are leguminous plants and have a symbiotic relationship with blue green algae

the blue green algae helps in the replenishment of nitrogen by taking it from the atmosphere and converting into the nitrogenous form that can be consumed by plants

So basically growing of these pulses helpsin the replenishment of nitrogen in the soil which can be used by other plants too.
