Question

state one advantage of growing a leguminous crop between two cereal crop?

Answer 1

Practice in which different types of crops like leguminous crops and non leguminous crops are grown alternately in the same field is called as Crop rotation.

Advantages of Crop Rotation:

1. Improves the fertility of soil by replenishing it with nitrogen .

2. Increases the production of food grains.

3. Saves lots of nitrogen fertilizers as leguminous plants can fix atmospheric nitrogen with the help of bacteria

Answer 2

HEY!!

✴The growing of paddy/wheat in a field leads to the deficiency of a particular nutrient like nitrogen which is used up by these particular crops in the field.

✴The leguminous plants contain nitrogen fixing bacteria Rhizobium attached to their roots.

✴This bacteria helps these plants to fix atmospheric nitrogen and convert it into usable form for plants.

✴Thus, these plants help to replinish the nutrients like nitrogen in soil. That is why, farmers are growing leguminous plant after growing paddy / whea.
