Q1. [1] medium thorough-understanding
Ragi, bajra and jowar are all millets, yet they thrive on different soils. At the same time, pulses are deliberately grown in rotation with these and other crops. What soil-related property of pulses makes them a logical rotation partner for millets and other cereals?

Model Answer

Pulses are leguminous crops that fix atmospheric nitrogen into the soil, thereby restoring soil fertility. This makes them a logical rotation partner, as they replenish the nitrogen depleted by millets and other cereals.

Explanation

The textbook explicitly states: "Being leguminous crops, all these crops except arhar help in restoring soil fertility by fixing nitrogen from the air. Therefore, these are mostly grown in rotation with other crops." For 1 mark, simply name the property (nitrogen fixation / restoring soil fertility) — one clear sentence is enough.
