Question

What type of plants are Jeeluga or Pillipesara which are cultivated to increase the fertility of the soil?
A. Ornamental plants
B. Cereals
C. Leguminous plants
D. Non-leguminous plants

Answer 1

Hint:The ability of land to support plant growth and maximize crop yield is soil fertility. Soil fertility can be further enhanced by integrating deck crops which add organic matter to the soil, resulting in better soil structure and a good, fertile soil.

Complete answer:
Jeeluga or Pillipesara:-
These crops are a product of green manure that is ploughing or becoming a soil in order to increase the fertility of the soil. Green manuring is primarily aimed at introducing organic matter to the ground.
Option A:- Ornamental plants Decorative plants, including plants for cut flowers and show samples, are grown for decorative purposes on projects for gardens and landscape design. These plants constitute an important addition to the landscape. This is a wrong response since the fertility of the soil is not improved by ornamental plants.
Jeeluga or Pillipesara which are cultivated to increase the fertility of the soil are not Ornamental plants. Hence, this option is incorrect.
Option B:- Cereals Cereals are classified as grains that provide more food than any other crop. Rice, wheat, rye, oats, barley and maize are the most common cereals cultivated. It is also an insufficient response as cereals are the foodstuffs and not the plants that supply the soil with food.
Jeeluga or Pillipesara which are cultivated to increase the fertility of the soil are not Cereals. Hence, this option is incorrect.
Option C:- leguminous plant A leguminous plant is a community of flowering plants with plants or foods grown from the bottom, which increase the capacity of nitrogen-rich substances. The soil fertility is improved through the bacteria of Rhizobium in the plants' roots. It is a right response since Jeeluga or pillipesara are leguminous plants grown to increase soil fertility. Jeeluga or Pillipesara which are cultivated to increase the fertility of the soil are leguminous plants. Hence, this option is correct.
 Option D:- Non-leguminous plants Non-legume plants are the wrong response, since these are plants that are not part of the Fabaceae family, generally referred to as legumes. Jeeluga or Pillipesara which are cultivated to increase the fertility of the soil are not Non-leguminous plants. Hence, this option is incorrect.

Hence the correct answer is option C.

Note:Scientists have the impression that growing vegetables at least once a season would help to improve soil fertility because they are able to use their root nodules to fix atmospheric nitrogen. This eliminates the use of chemicals such as urea and nitrate ammonium. Scientists have found out that legumes start to yield and suit in any cropping system within 45 to 50 days of seeding.
