Crop rotation is employed for

  1. Increasing nitrogen content of soil

  2. Checking soil erosion

  3. Community development

  4. Enhancing soil fertility
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in during different seasons. It is done so that the soil is not depleted of a particular type of  nutrients. It helps in reducing soil erosion and increases soil fertility and crop yield. 

So, the correct answer is 'Enhancing soil fertility'

Cereals and legumes are cultivated alternatively in crop rotation process by a farmer. Which of the following are advantages of cultivating cereals and legumes alternatively?

  1. When cereals are cultivated more nutrients are utilized

  2. If legumes are grown in the soil, less nutrients are utilized

  3. Legumes synthesize some nutrients as they have root nodules

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Cultivation of cereals followed legumes in a cultivated soil is called crop rotation. In this, Legumes have bacteria on nodules which are on the roots of the plant. The bacteria on the nodules takes nitrogen from the air and fixes it into the soil, so that other plants that require nitrogen can use it as well.  Farmers use soybeans and other legumes in rotations with grass crops such as corn or wheat. Grass crops are unable to take their own nitrogen from the air so they either need the nitrogen in the soil that the legumes provide for them in a crop rotation or they need a chemical fertilizer containing nitrogen. 
So the correct option is ' All of the above ' .

Which of the following is not a characteristic of mixed cropping?

  1. Minimize risk of crop failure

  2. Set pattern of rows

  3. Harvesting and threshing crops separately is not possible

  4. Individual marketing and consumption of crop is not possible
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mixed cropping is a type of cultivation in which two types of crops are grown at a time and in the same piece of land. It is a form of polyculture. The characteristic of mixed cropping is balancing the nutrient level on soil, suppression of weed and insect pests, minimize the risk of crop failure etc.

So, the correct option is 'Individual marketing and consumption of crop is not possible'.

Which of the following methods are used to restrict soil erosion ? 
(A) Ploughing along contour lines
(B)  Strip cropping
(C) Jhumming
(D) Mixed farming

  1. A and B

  2. A and C

  3. B and D

  4. B and C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Contour ploughing (or contour ploughing) or contour, farming is the farming practice of ploughing across a slope following its elevation contour lines. 


The rows form slow water runoff during rainstorms to prevent soil erosion and allow the water time to settle into the soil.
 Strip cropping is a method of farming used when a slope is too steep or too long, or otherwise when one does not have an alternative method of preventing soil erosion. 

Hence, the correct option is $\text{A}$

The egg laying capacity of an Indian hen breed is_____________.

  1. 100 eggs per year

  2. 50 eggs per year

  3. 200 eggs per year

  4. 1000 eggs per year
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Indian breeds of hens, such as Aseel or Kadaknath, typically have lower egg-laying capacities compared to commercial hybrids. 200 eggs per year is a standard estimate for improved Indian breeds.

What is the advantage of crop rotation?

  1. Getting different kinds of crops

  2. Increasing the quality of minerals

  3. Increasing the fertility of soil

  4. Increasing the quality of proteins
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Crop rotation is a traditional practice of growing different crops in the same area, so as to increase the fertility of the soil. 
  • This process helps to build up the lost nutrients of the soil and when the rotation is done with growing cereals, it replenishes the nitrogen levels of the soil because crop rotation is mostly done by using legumes and paddy crops.
So, the correct answer is option C.

Which of these is not a major group of activities for improving crop yield?

  1. Crop protection management

  2. Crop production management

  3. Crop variety improvement

  4. Crop transport management
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Many different management programs are undertaken in order to improve the yield of the crop plants. The crop protection, production, and variety improvement are the management programs which help to enhance the yield of the crop. The transport management is not a part of crop yield increase. 

Thus, the correct answer is option D.

Mole drainage is practised extensively in country

  1. New Zealand

  2. Japan

  3. U.S.A.

  4. China
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mole drainage is widely used in New Zealand and the United Kingdom in heavy soils to improve productivity of pastures and crops. Mole drains are used in heavy soils where a clay subsoil near moling depth (400 to 600 cm) prevents downward movement of ground water. The aim of mole drainage is to fracture and crack the soil in order to improve the capacity of the soil to transmit water. Mole drainage is used in impermeable soils as a cost-effective means of facilitating a shallow pipe drain network. Mole drainage is suited to soils with a high clay content which form stable channels.

Which of the following is one of the reasons why IT can play a critical role in achieving sustainabledevelopment and food security in the thetwenty-first century?

  1. IT can help in educating people from rural areas about the risks involved in farm-related occupations.

  2. IT can help in disseminating information regarding prices, weather and soil conditions for

    growing different crops etc.

  3. IT can shift occupations from the farm economy by pushing dependent people to urban areas.

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

The IT has revolutionised many sectors in the Indian economy. There is broad consensus that IT can play a critical role in achieving sustainable development and food security in the twenty-first century. 

Governments can predict areas of food insecurity and vulnerability using appropriate information and software tools so that action can be taken to prevent or reduce the likelihood of an emergency.It also has a positive impact on the agriculture sector as it can disseminateinformation regarding emerging technologies and its applications, prices, weather and soil conditions for growing different crops etc. 

Though IT is, by itself, no catalyst for change it can act as a tool for releasing the creative potential and knowledge embedded in the society. It also has the potential of employment generation in rural areas.
