Question 2
1 / -0

A
Healthy seeds being lighter float on the surface of water.

B
Damaged seeds being lighter float on the surface of water.

C
Some healthy seeds and some damaged seeds float on the surface of water.

D
Damaged seeds being heavier settle down at the bottom.
Question 3
1 / -0

The period of crop harvesting is celebrated with great joy and happiness in all parts of India. Special festivals are associated with the harvest season. Which among the following group of festivals is associated with harvest season?

A
Pongal, Holi, Diwali, Nabanna

B
Diwali, Christmas, Eid, Pongal

C
Pongal, Eid, Holi, Nabanna

D
Pongal, Baishakhi, Eid, Nabanna

Solution

Holi, Diwali and Nabanna are the festivals associated with harvest season while Christmas and Eid are not associated with harvest season.
Question 4
1 / -0

Crop plants may be attacked by pests which affect the crop production. Fungi are such type of pests which cause diseases like

A
Smut of wheat

B
Citrus canker

C
Blight of potato

D
Both (a) and (c).

Solution

Loose smut of wheat is caused by fungus Ustilago tritici, early blight of potato is caused by fungus Alternaria so/an/ and late blight of potato is caused by fungus Phytophthora infestans. Citrus canker is a bacterial disease caused by bacterium Xanthomonas.
Question 5
1 / -0

Which of the following statements are correct?

(i) Cochineal insect is used to eliminate Opuntia.
(ii) Water logging decreases the amount of salts in the soil that increases soil fertility.
(iii) Fertilisers are not readily soluble in water, so they are absorbed by the plants slowly.
(iv) Rust of wheat is a fungal disease.
(v) The practice of growing two or more dissimilar crops in the same field one after the other is called mixed cropping.

A
(i), (ii), (iii) and (v) only

B
(i) and (iv) only

C
(ii) and (iv) only

D
(iii), (iv) and (v) only

Solution

Water logging decreases the amount of salts in the soil that reduces soil fertility. Fertilisers are soluble in water, they are directly absorbed by plants and greatly increase crop yield. The practice of growing two or more dissimilar crops in the same field simultaneously is called mixed cropping.
Question 6
1 / -0

The cutting and gathering of crop after it is matured is called X. After this, grains are separated from the crop by a process called Y. Z is the process of separating the hay and chaff from the grains.

Which of the following statements is/are correct regarding X, Y and Z?

A
Z is done with the help of wind in which grains along with husk is allowed to fall from a height.

B
X is done mechanically by combine and manually by plough and harrow.

C
X is the process known as threshing whereas Y is the process known as winnowing.

D
Both (a) and (b)

Solution

The cutting and gathering of crop after it is matured is called harvesting. After this, grains are separated from the crop by a process called threshing. Winnowing is the process of separating the hay and chaff from the grains. Harvesting is done mechanically by combine and manually by sickle.
Question 7
1 / -0

A few healthy gram seeds are placed in each of the three pots X, Y and Z containing same type of soil.

The soil in pot X is mixed with some green leaves. The soil in pot Y is mixed with old cow dung while soil of pot Z is mixed with urea. Pots are watered regularly and given proper environment for plant-growth. Which of the following will be observed after 10 days?

A
Lot of growth in Z with replenishment of all the nutrients.

B
Lot of growth in X without replenishment of any nutrient.

C
Lot of growth in V with replenishment of the nutrients.

D
Both (a) and (c)

Solution

The given pot X, Y and Z contains green manure, manure and fertiliser respectively. Green manures and manures replenish soil with nutrients while fertiliser has no role in replenishment of nutrients.

Question 8

1 / -0

The different steps of agricultural practices are given below randomly.

(i) Irrigation	(ii) Ploughing
(iii) Weeding	(iv) Levelling
(v) Harvesting	(vi) Fertilisers
(vii) Sowing	(viii) Crop protection
(ix) Storing seeds

Which of the following represents the correct sequence of these practices?

(ii) - (iv) - (vii) - (i) - (vi) - (iii) - (viii) - (v) - (ix)

(iv) - (ii) - (vii) -(i)-(vi)- (iii) -(viii) - (v) - (ix)

(ii) - (vii) - (iv) - (iii) - (i) - (v) - (vi) - (viii) - (ix)

(iv) - (vii) - (i) - (ii) - (iii) - (viii) - (ix) - (v) - (vi)

Question 9
1 / -0

The semi-arid plains of a particular region show a pattern of alternating yellow and black stripes on the ground. The yellow stripes consist of land covered by ripening wheat. The black stripes are bare soil on which no crop is grown but farmers use herbicides or tillage to remove any weeds that try to grow in that region.

Why do farmers in this region manage soils in this way?

A
Farmers put the half of their land to rest for minimising erosion and soil degradation.

B
Farmers discourage transpiration in the wheat plantation by allowing free evaporation from the soil of the bare stripes.

C
Farmers try to store some part of one year's rainwater in the soil under the bare stripes and use that water to supplement the rain on wheat crop planted the next year.

D
All of these
