Why does a farmer plough his fields in summer?

  1. To prevent alkalinity of soil

  2. To prevent acidity of soil

  3. To prevent the surface from becoming hard

  4. To fertilize the soil
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
In Summer Ploughing, due to breaking of hard crusted upper layer of the soil and deep ploughing the infiltration capacity and permeability of the soil increases which increases in-situ moisture conservation. Consequently plant roots will get more moisture with less effort. It also improves soil structure due to alternate drying and cooling and soil aeration which helps in multiplication of micro-organisms. This is the reason that farmers plough their field during summer.

Green audit is

  1. Estimation of crop yield and crop area

  2. Estimation of forested area and pasture land

  3. Checking of impact of an establishment over environment

  4. Effect of environment over vegetation of an area
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Green audit is basically the evaluation or assessment of environmental conditions. It includes the identification, reporting and then analysis of various components of diversity of environment. The aim of green audit is to upgrade and improve the environmental conditions. Various changes have occurred in the environment over a period of time due to industrialisation and commercialisation. So, green audit assess the impacts of establishments over environment.
So, the correct answer is 'Checking of impact of an establishment over environment'.

Main objective of production of herbicide resistant GM crops is to?

  1. Encourage eco-friendly herbicides

  2. Reduce herbicide accumulation in food articles for health safety

  3. Eliminate weeds from the field without the use of manual labour

  4. Eliminate weeds from the field without the use of herbicides
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Herbicide-tolerant plants are plants whose growth and development are not significantly affected by herbicides used on the weeds growing around them. 

These types of plants were developed to help farmers control weeds without the use of manual labour that competes with crops for soil, space, water, and sunlight. 
So, the correct option is 'Eliminate weeds from the field without the use of manual labour'.

How can we increase the food production?

  1. By agrochemical based agriculture

  2. By Organic agriculture

  3. By genetically engineering crop- based agriculture.

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Organic agriculture will help improve food production as it involves production system that relies on ecological processes, biodiversity and cycles adapted to local conditions and does not involve the use of pesticides, fertilizers or other genetically modified organisms etc. Use of genetically modified crop-based agriculture techniques, on the other hand, will help increase yield and also provide the plants with resistance to diseases. 


So, the correct option is 'By genetically engineering crop- based agriculture'.

Study the following ststements regarding organic farming and select the correct ones.
(i) It utilities genetically modified crops like Bt cotton.
(ii) It uses only naturally produced inputs like compost and biofertilisers.
(iii) It does not use pesticides and urea.
(iv) It produces vegetables rich in vitamins and minerals.

  1. (i) and (ii)

  2. (iii) and (iv)

  3. (ii) and (iii)

  4. (ii), (iii) and (iv)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In organic farming, farmers use manures, bio fertilisers, biopesticides and biocontrol agents to increase the crop production instead of using artificial fertilisers and pesticides. It does not utilise genetic engineering.

Organic farming does not include:

  1. Green manures

  2. Chemical fertilisers

  3. Farmyard manures

  4. Compost
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Organic farming includes several methods to enhance soil fertility. In such farming, methods of biological origin are used, e.g., biopesticides, biofertilisers, IPM (Integrated Pest Management) green manure, bioherbicides, keeping pests and pathogens under control, etc. Chemical fertilisers are not used in organic farming.

Crop rotation is an important part of organic farming. Why is monocropping problematic?

  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.
Reveal answer Fill a bubble to check yourself
B Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

A Correct answer
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.

Organic farming completely relies on

  1. Chemical fertilizers

  2. Sustainable techniques

  3. Growth hormones

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
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.
