What is the main advantage of transplantation method in rice cultivation?

  1. This method ensures maximum utilization of land

  2. It is helpful in achieving an economical use of water and a highest yield

  3. It helps in early harvesting

  4. The draining of water from the field before harvesting is made easy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Advantages of transplanting:

Plant population becomes more assured.
Since nurseries occupy only 1/10 of area of the main crop, the irrigation, control of insects and diseases and other management become easier to reduce the cost of raising seedlings as compared to a broadcast wet crop of the same age. Nurseries raised in advance, enable the crop to be planted in the field at the right time.
The seedlings are grown up at the time of transplanting and they are able to compete with young weeds that spring up. Weed control and other inter-cultural operation are much easier, particularly in row planting.

Which of the following methods of cultivation makes soil fertile?

  1. Excessive use of chemical fertilizers

  2. Extensive cultivation

  3. Crop rotation

  4. Monocropping
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Crop rotation is the practice of growing of different types of crops in alternate season. The cash crops grown in one season is replaced by leguminous plants in the other season. The nutrients which are used up by the previous crops are regained by the second crops. So, crop rotation maintains soil fertility and prevents soil erosion.

So, the correct answer is option C.

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.

Which of the following can be an advantage of crop rotation?

  1. Crop rotation makes the soil fertile.

  2. Helps in the production of crop yield.

  3. Leguminous plants grown during crop rotation fix atmospheric nitrogen and enrich the soil with nitrogen compounds.

  4. All of the above.

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.

So, the correct option is 'All of the above'.

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.

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'
