Answer:
Pea and Soybean are the kharif and Rabi crops that increase the nitrogen content of the soil respectively as they are leguminous plants. These plants form a symbiotic association with Nitrogen fixing bacteria Rhizobium in root nodules. The roots are left in the soil after harvest.

rabi crop = wheat. leguminous plant replenish nitrogen in soil because there is 1 or 2 bacteria whose name azatobactor and rhizobium found in the noodles of root of the legumes plants that fix atmospheric nitrogen to the soil.
