Weekly Quiz Competition

Question 1
1 / -0

.......... is the artificial application of water to the land or soil:

A
Ploughing

B
Irrigation

C
Rainwater farming

D
Tilling

Solution

Irrigation is a system or process of supplying water to the fields where the crops are being grown. It was started due to the deficiency of rainfalls. Irrigation also makes the soil more fertile and nourishes the crop. It is an artificial method of supplying water into the fields.
So, the correct option is 'Irrigation'.
Question 2
1 / -0

Which of the following describes the advantage of ploughing ?

A
It allows the penetration of roots of plants.

B
It helps in proper aeration and eradicates weeds.

C
It promotes the growth of useful soil bacteria.

D
All of the above.

Solution

Ploughing is the method which helps in the loosening of the soil to aerate the soil. It allows space for the penetration of the roots of the crop plants. The aeration helps the plants to respire properly and there is the eradication of the weeds. This movement of the soil helps in the growth of the beneficial soil bacteria.
Thus, the correct answer is option D.
Question 3
1 / -0

Which of the following can help in enriching the fertility of the soil?

A
Reuse of land

B
Crop rotation

C
Tilling

D
Cutting of trees

Solution

Crop rotation is the process of growing different types of crops in the same area one after the other. If the same type of crop is planted one after the other, the soil gets deprived of a single nutrient. The process of crop rotation avoids this situation and maintains all the nutrients in the soil. It uses grain legumes which enhances the soil fertility through biological nitrogen fixation. So, the answer is B.
Question 4
1 / -0

In which of the following agricultural methods does the farmer sow beans in his fields after harvesting a crop of wheat?

A
Crop rotation

B
Multiple cropping

C
Fallow field

D
Mixed cropping

Solution

The crop rotation is a pattern of growing a series of different types of crops in the same area in the sequential season. It is a method of replenishment of nutrients. For example, the harvesting of wheat is followed by the sowing of beans. Beans are leguminous plants and therefore, contain nitrogen-fixing bacteria in their root nodules. Growing beans will replenish the soil with nitrogen.
Thus, the correct answer is option A.
Question 5
1 / -0

Identify the use of a seed drill.

A
It is used to put manure or fertiliser near the roots of trees.

B
It is used to sow the seeds at equal distances.

C
It is useful to remove weeds in a field.

D
Both A and B.

Solution

Seed drill is a device that sows the seeds in the soil and covers them to a certain depth. It helps to sow the seeds at equal distance and proper depth to save the seeds from being eaten by birds. This practice is used to overcome the problems of sowing done by hand. The use of a seed drill can improve the ratio of crop yield.
Thus, the correct option is B.
Question 6
1 / -0

What are the negative impacts of tilling on soil?

A
Loss of nutrients

B
Organic matter reduced

C
Eutrophication

D
All of the above

Solution

Tillage of crop affects the soil quantity. It disrupts the soil structure and leads to soil erosion and eutrophication. Tillage also reduces crop residue. It leads to the destruction of the crop.
So, the correct option is 'All of the above'.
Question 7
1 / -0

Identify the advantage of proper storage.

A
The quality of food is ensured for a longer time.

B
The variety of food may be available in far places.

C
The food poisoning is prevented.

D
All of the above

Solution

Proper storage of food helps in maintaining food quality by retaining flavor, colour, texture and nutrients, while reducing the chance of contracting a food-borne illness. It has various advantages as the quality of food remain intact therefore it can be used for longer time, it can be made available at far places where such food is not harvested and since it remains unaffected by microbes, food poisoning can be prevented.
So, the correct answer is option D.
Question 8
1 / -0

Which of the following is not an organic method used to control weeds?

A
Seedling bed

B
Weedicides

C
Intercropping

D
Crop rotation

Solution

A seedling bed is a piece of land in which seed plantation is done. This technique is used to maximize seed germination and not to control weeds.
Weedicides are chemicals used to destroy weeds.
Intercropping is the cultivation of two or more crops on the same field simultaneously in a row pattern. When different crops are planted in the same field same insect pests and plant pathogen cannot harm both crops.
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 over the same field and enhances the health of crops. Hence it minimizes the amount of pest and increases crop production.
Thus the correct answer is option B.
Question 9
1 / -0

Like paddy, the method of sowing seeds of tomato is:

A
Drill

B
Broadcasting

C
Transplantation

D
None of the above

Solution

In agriculture, transplantation is the indirect method of seeding. In this method, a seed is grown in a nursery bed or a greenhouse. After some time, the seed grows into a seedling and is then transferred to the field. It is common in some plants like tomato, eggplant, peppers, fruit trees, African oil palm, coconut, and many ornamental crops. This method is important for extending the growing season, protecting young plants from diseases and pests. It is also important for avoiding germination problems seen in the method of direct seeding.
So, the correct option is C.
Question 10
1 / -0

Why is organic manure considered better than fertilizers?

A
It cannot be prepared in fields

B
It is less rich in plant nutrients

C
It improves the fertility and texture of the soil

D
It decreases the water holding capacity of the soil

Solution

Organic manure or organic fertilizer is made up of organic biodegradable waste like animal excreta and agriculture wastes. As it biodegradable it cannot harm the environment and increase the soil fertility it is better than chemical fertilizer. But chemical fertilizers are nutrient specific and prepared in chemical factories. Thus, the correct answer is option C.
