Questions Related to botany

Crop production without using chemicals is called as

  1. Crop farming

  2. Organic farming

  3. Crop rotation

  4. None of the above


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


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. 

All of the following are associated with organic farming except

  1. Cross breeding

  2. Biofertilizers

  3. Biopesticides

  4. Green manure


Correct Option: A
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. There is combination of farming with traditional methods and maintenance of livestock. There is use of biofertilizers and biopesticides which include the use of live organisms for providing nutrition to the plants. Green manure is used for increasing the soil fertility. This also improves the water-holding capacity of the soil. 

Thus, the correct answer is option A. 

Identify the integrated farming of crops and livestock.

  1. Organic farming

  2. Mixed cropping

  3. Composite farming

  4. None of the above


Correct Option: A
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. 

Thus, the correct answer is option A. 

Organic farming completely relies on

  1. Chemical fertilizers

  2. Sustainable techniques

  3. Growth hormones

  4. None of the above


Correct Option: B
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. The method completely relies on sustainable techniques like microbial inoculation which doesn't pose a threat to the environment. This system uses the microbial culture to enhance the soil quality and fertility. The activity of the microbes adds nutrients to the soil. These nutrients can be used by the plants for growth and development. The technique involves the use of cattle and other farm animals for farming. There is use of green manure, biofertilizers and biopesticides. 

Thus, the correct answer is option B. 

Consider the following statements (A-D) about organic farming

(A) Utilizes genetically modified crops like Bt cotton.
(B) Uses only naturally produced inputs like compost.
(C) It does not use pesticides and urea.

(D) Produces vegetables rich in vitamins and minerals.

Which of the above statements are correct?

  1. (B) and (C) only

  2. (A) and (B) only

  3. (B), (C), and (D)

  4. (C) and (D) only


Correct Option: A
Explanation:

A- Organic farming is the method of cultivation of crops through use of fertilizers of organic origin such as green manure, compost, bonemeal etc. It uses techniques such as crop rotation and companion plantation. Synthetic fertilizers and pesticides are strictly prohibited. 

Horticulture is related to

  1. Olericulture

  2. Floriculture

  3. Pomology

  4. All of the above


Correct Option: D
Explanation:

Horticulture has been defined as the culture of plants for food, comfort and beauty. It includes plant conservation, landscape restoration, soil management, landscape and garden design, construction, and maintenance, and arboriculture. It also includes Olericulture (science of vegetable growing, dealing with the culture of non-woody (herbaceous) plants for food), Floriculture, or flower farming(discipline of horticulture concerned with the cultivation of flowering and ornamental plants for gardens and for floristry, comprising the floral industry) and Pomology(is a branch of botany that studies and cultivates fruit). Hence, the horticulture is related to olericulture, floriculture and pomology.

So, the correct answer is 'All the above'.

Horticulture deals with management of

  1. Farms

  2. Orchards and gardens

  3. Trees and shrubs

  4. Forests


Correct Option: B
Explanation:

Horticulture is the science or art of cultivating fruits, vegetables, flowers, or ornamental plants. It impacts our lives on a daily basis by providing nutritious fruits and vegetables, offering visual enjoyment, and promoting recreational activities.

So the correct option is 'Orchards and gardens'.

Growing trees and shrubs in small pots is

  1. Bonsai

  2. Culture

  3. Green gardening

  4. Tree culture


Correct Option: A
Explanation:

Bonsai is an art of growing trees and shrubs in small pots or containers. It is originated from Chinese horticulture practice. In this, ornamental dwarf plants are grown in pots. Once potted, it is regularly shaped to limit its growth.

Thus, the correct answer is option A.

Vegetable cultivation comes under

  1. Horticulture

  2. Agriculture

  3. Olericulture

  4. Floriculture


Correct Option: C
