Weekly Quiz Competition

Question 1
1 / -0

Identify the correct statements about manure.
i) Manure contains large quantities of organic matter.
(ii) It increases the water-holding capacity of the soil.
(iii) Manure is produced synthetically.
(iv) Its excessive use pollutes the environment because it is made from animal wastes.

A
(i) and (iii)

B
(i) and (ii)

C
(ii) and (iii)

D
(iii) and (iv)

Solution

Manure contains large quantities of organic matter and it is added to the soil to increase its fertility. Manure increases the water-holding capacity of the soil. This makes more water available to the plants. Manure is produced naturally by decomposing plant and animal wastes with the help of microorganisms. It prevents environmental pollution because it recycles plant and animal wastes. Therefore, option B is correct.
Question 2
1 / -0

The common weedicide used in agricultural fields is:

A
2,4-D

B
2,4,5-T

C
Indole acetic acid

D
Abscissin

Solution

Weedicides can be defined as the pesticides used to kill weeds. 2,4-D (2,4-dichlorophenoxyacetic acid) is a herbicide developed in the 1940s and is still in use today. The low cost of 2,4-D has led to continued usage, and it remains one of the most commonly used herbicides in the world.
Hence, the correct answer is option A.
Question 3
1 / -0

A few gram seeds were placed in each of the three pots A, B and C containing soil. The soil in Pot A is mixed some green twigs and leaves. The soil in pot B is mixed with old cow dung while soil of pot C is mixed with urea. Pots are watered regularly. Which of the following will be observed after 10 days?

A
Lot of growth in A

B
Not much growth in B

C
Lot of growth in B but very little growth in C

D
Very little growth in A but lot of growth in B and C

Solution

Manure is an organic substance produced by the decomposition of plant and animal wastes in the presence of microorganism and used as fertilizers. Thus, the fresh manure contains decomposing bacteria along with active digestive enzymes. These enzymes contribute to the faster heating of the manure which accelerates the decomposition of organic materials by the soil microorganisms. The end result of better decomposition of organic material is faster nutrient release to the plant. When urea is placed on the surface of the soil, a chemical reaction takes place that changes the urea to ammonium bicarbonate. Urea should be mixed in with the soil for maximum effectiveness. For plants that love acidic soils, urea is one of the top fertilizers for acidifying soils. Hence, seeds will grow most in pots B and C.
Question 4
1 / -0

Cultivation of kharif crops starts in ................. in the North Indian states.

A
June

B
September

C
October

D

A
Traditional tool

B
Seed drill method

C
Both A and B

D
None of these
Solution
The tools used for sowing seeds are as follows:
Traditional Tool- The tool used traditionally for sowing seeds is shaped like a funnel. The seeds are filled into the funnel, passed down through two or three pipes having sharp ends. These ends pierce into the soil and place seeds there.
Seed Drill- Nowadays the seed drill is used for sowing with the help of tractors. This tool sows the seeds uniformly at proper distances and depths. It ensures that seeds get covered by the soil after sowing. This prevents damage caused by birds.
Sowing by using a seed drill saves time and labour.
Therefore, the correct answer is option C.
