Question 1
1 / -0

Intergeneric hybridisation is the process of crossing between plants of

A
same genera

B
different genera

C
two different divisions of same kingdom

D
two different divisions of different kingdoms

Solution

In intergeneric hybridisation, crossing is carried out between plants of different genera.

The correct answer is B.
Question 2
1 / -0

Variety improvement of plants is carried out to obtain desirable characteristics in crop plants.
Which of the following agronomic characteristics is desired in cereal crops?

A
Dwarfness

B
Tallness

C
Large leaves

D
Small leaves

Solution

Dwarfness is the desired agronomic characteristic in cereal crops as it reduces the uptake of nutrients by plants.

Hence, the correct answer is option A.
Question 3
1 / -0

Which of the following factors can lead to a decrease in crop yield?

A
Favourable weather conditions

B
Adequate water supply

C
Low soil salinity

D
Low soil quality

Solution

Low soil quality is one of the factors that can decrease crop yield.

The correct answer is D.

Why alternatives A, B and C are wrong:

Factors such as adequate water supply, favourable weather conditions, and low soil salinity increase crop yield.
Question 4
1 / -0

Which of the following statements about manure is incorrect?

A
It increases the fertility of soil

B
It promotes water-logging in fields

C
It improves the soil structure of fields

D
It increases the water-holding capacity of soil

Solution

Manure does not promote water-logging in fields. Water-logging does not occur in fields that have clayey soil because of manure.

Hence,the correct answer is option B.
Question 5
1 / -0

Plants obtain some nutrients from water. Which of the following nutrients is obtained by plants from water?

A
Carbon

B
Hydrogen

C
Nitrogen

D
Chlorine

Solution

Plants obtain hydrogen from water.

The correct answer is B.

Why alternative A is wrong:

Plants take up carbon from air.

Why alternatives C and D are wrong:

Nitrogen and chlorine are taken up by plants from soil.
Question 6
1 / -0

The primary disadvantage of using fertilizers over manure is that

A
their long term use can reduce the oxygen content of soil

B
they add nitrogen, phosphorus, and potassium to soil

C
their long term use can reduce the fertility of soil

D
they increase the microbial population in soil

Solution

The excessive use of fertilizers reduces the fertility of soil. The inorganic matter present in fertilizers harms the microorganisms present in the soil and stops the replenishment of the organic matter.

The correct answer is C.

Why alternative A is wrong:

The long term use of fertilizers does not reduce the oxygen content of soil. It reduces the fertility of soil.

Why alternative B is wrong:

Fertilizers add nitrogen, phosphorus, and potassium to soil. These nutrients are required by plants.

Why alternative D is wrong:

The excessive use of fertilizers decreases the microbial population in soil.
Question 7
1 / -0

Which macronutrients is supplied by fertilizers?

A
Phosphorus

B
Boron

C
Zinc

D
Chlorine

Solution

Phosphorous is a macronutrient. Fertilizers supply phosphorus, along with nitrogen and potassium, to plants.

The correct answer is A.
Question 8
1 / -0

Use the following information to answer the next question.

There are different kinds of irrigation systems such as canals, wells, rivers, and tanks.

Which irrigation system taps water from the water-bearing strata of soil?

A
Canals

B
Tanks

C
Dug wells

D
Tube wells

Solution

Dug wells tap water from the water-bearing strata of soil.

Hence,the correct answer is option C.

Why alternative A is wrong:

Canals are elaborate and extensive irrigation systems that receive water from reservoirs or rivers.

Why alternative B is wrong:

Tanks are small storage reservoirs that intercept and store the run-off water from smaller catchment areas.

Why alternative D is wrong:

Tube wells tap water from the deeper strata of soil.
