Rotation of crops is carried out to

  1. Increase convenience for the farmers

  2. Increase variation in the mineral content of soil

  3. Increase in nitrogen content of the soil

  4. Increase diversity of plant habitats
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The practice of growing a series of different types of crops in the same area in sequenced seasons is called crop rotation.
The advantages of crop rotation are:-
1) It helps in reducing soil erosion.

2) It increases soil fertility and crop yield.
3) The soil of farms do not get deficient of one type of nutrients.
So, the correct answer is 'Increase variation in the mineral content of soil'.

Which of the following conditions are developed due to monoculture?

  1. Multiplication of parasites

  2. More food production

  3. Less use of toxic chemicals

  4. Ecosystem balance in undisturbed
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Monoculture involves growing a single crop over a large area, which reduces biodiversity and makes the crop more susceptible to the rapid spread of pests and parasites.

Rotation of crops helps in

  1. Insect control

  2. Altering chemical nature of soil

  3. Improving soil fertility and yield

  4. Proliferating weeds
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Crop rotation refers to the practice of growing different types of crops in the same area over a sequence of seasons. Different types of plants require different types of nutrients from the soil. Changing crops routinely allows the land to remain fertile, since not all of the same nutrients are being used each season. For example, planting a legume, such as soybeans, helps to replenish necessary nitrogen in the soil. Crop rotation has helped to increase productivity by replacing cultivated lands that has not been used for one or more seasons with growing different crops that replenish soil nutrients.

D Correct answer
Explanation

Crop rotation is the process of successive growing of crop in the same field. This helps in increasing the fertility of the soil. Helps in a good production of the crop. It decreases the population of pests. It also reduces soil erosion.

What benefits are obtained due to crop rotation?

  1. Increase in production

  2. Soil fertility

  3. Weed control

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

Rotation of crops improves the fertility of the soil and hence, brings about an increase in the production of food grains. It helps in saving on nitrogenous fertilizers, because leguminous plants grown during the rotation of crops can fix atmospheric nitrogen in the soil with the help of nitrogen fixing bacteria. Rotation of crops help in weed control and pest control. Crop rotation adds diversity to an operation.

Which of the following statements is not true?

  1. The rotation of crops improves the fertility of soil.

  2. The rotation of crops saves a lot of nitrogenous fertilisers.

  3. The rotation of crops helps in weed and pest control.

  4. The rotation of crops helps in the maintenance of nutrients in the soil.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Crop rotation is a pattern of growing different types of crops in the same area. This method helps in the replenishment of nutrients by the regular succession of crops over the same field and enhances the health of crops. It minimizes the use of nitrogenous fertilizers. The nutrient quality of the soil can be maintained. There is no effect on the weeds and pests. 

Thus, the correct answer is option C.

Rotation of crops is essential for

  1. Increasing the quantity of proteins

  2. Increasing the quantity of minerals

  3. Increasing fertility of the soil

  4. Getting different kinds of crops
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

(c) If the same crop is grown year after year, fertility of soil is lost due to utilization of same minerals again and again. Soil fertility is usually maintained in the field by rotation of crops i.e., a crop is alternated by a leguminous crop.

Crop rotation is used by farmers to increase

  1. Nitrogenous content of soil

  2. Organic content of soil

  3. Community area

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

Crop rotation is the practice of growing of different crops in succession on a piece of land to avoid depletion of  a particular type of nutrient from the soil and to control the weeds , pests  & diseases . Other main reason of crop rotation is to give the soil the time to regain it's fertility 

So, the correct answer is 'Soil fertility'

  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 $\text{A}$

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.
