  2. Breeding of animals

  3. Study of soil

  4. Production of fruits and vegetables

Show answer
Correct Option: D
Explanation:

Horticulture is the branch of science that deals with the art and technology of growing plants. It includes the cultivation of fruits, vegetables, medicinal plants, ornamental plants and other plants. Agriculture is the science that deals with the study of the production of crops. Breeding of animals is called animal husbandry. Study of soil is called pedology.

  1. The crop is vulnerable to organized crop thieves.

  2. It encourages the build-up of diseases and pests that destroy that particular crop.

  3. It does not use minerals.

  4. It is expensive.

Show answer
Correct Option: B
Explanation:

Monocropping is problematic as it encourages the buildup of diseases and pests that destroy that particular crop. It decreases the total land productivity. In monocropping, the farmer is dependent on a single crop so the risk of crop failure increases which leads to economical loss.

So, the correct answer is option B.

Crop production without using chemicals is called as

  1. Crop farming

  2. Organic farming

  3. Crop rotation

  4. None of the above

Show answer
Correct Option: B
Explanation:

Organic farming is a system which involves those practices which maintain the natural fertility of the soil. It avoids or largely excludes the use fertilizers, pesticides, hormones and relies upon crop rotations, crop residues, animal manures and biological system of nutrient mobilization and plant protection.

Thus, the correct answer is option B.

In the long term, which of these saves energy and protect the environment?

  1. Crop rotation

  2. Mixed cropping

  3. Organic farming

  4. Fish farming

Show answer
Correct Option: C
Explanation:
Organic farming is the technique which is used for the evolution of the agricultural techniques and increase the production without the use of antibiotics, fertilizers and pesticides. Organic farming is a combination of farming with traditional methods and maintenance of livestock. This livestock includes cattle and other farm animals. This system also uses the microbial culture to enhance the soil quality and fertility. The animals and the microbes are used for the production of crops. There is no problem of pollution or leaching of the chemicals into the water system. This type of farming saves energy and money. There is no harm to the environment due to the activities performed during organic farming. 
Thus, the correct answer is option C.
