Question

Veera wants to practice crop rotation in his field suggest a Rabi crop and kharif crop which is replenished his filled with nitrogen Which crop replenishes nitrogen and why.

Answer 1

Veera should grow wheat as rabi crop and soyabean or pea as kharif crop for crop rotation.

Crop rotation is the practice of cultivating two different crops on two different seasons altenatively, the crops are cultivated in such a way that the nutrient need of one crop is ful-filled by the other.

Soyabean is a leguminous plant. The root nodules of leguminous plant contain a bacteria called rhizobium bacteria that turn the free atmospheric nitrogen into soluble form so that the soluble nitrogen can be absorbed by the roots of plants along with water.

If wheat is grown in rabi season which requires a lot of nitrogen and if the next crop is of a leguminous plant like pea or soyabean then the nitrogen can be naturally replenished by the leguminous plants.

Due to this reason Veera should grow leguminous plants like pea or soyabean as kharif crop and wheat in rabi crop for the practice of crop rotation.
