Question 1
1 / -0

Consider the following statements and select the option which correctly identifies true (T) and false (F) ones.

(i) Growing different crops in different seasons in the same field will deplete the nutrients of soil.

(ii) Freshly harvested grains must be dried before sowing.

(iii) Manures are mineral specific as they provide all the minerals needed by plant.

(iv) Broadcasting of seeds is done by seed drill

F T F T

Solution

Growing different crops in different seasons in the same field will enrich the nutrients of soil. Broadcasting is the method of sowing seeds in which seeds are scattered in the field by hand or manually. Manures are rich in organic matter and are not mineral specific.

Question 2

Match different terms in column I with their related description in column II and select the correct option from the codes given below.

Column I	Column II
(a) Weeding	(i) Loosening and turning of soil.
(b) Threshing	(ii) Removing unwanted plants from a field.
(c) Tilling	(iii) Cutting and gathering of mature crop
(d) Harvesting	(iv) Separation of grain from the chaff

Select the incorrect match.

(i) Kharif crop: Paddy and wheat

(ii) Rabi crop: Mustard and linseed

(iii) Storage of grains: Silos and granaries

(iv) Weeds: Amaranthus and Chenopodium

A

Question 4
1 / -0

Which of the following is/are incorrect statements) regarding manure?

(i) Manure enhances the water holding capacity of the soil.

(ii) Manure is nutrient specific i.e. supply a particular desired nutrient.

(iii) Manure decreases the number of friendly microbes.

(iv) Manure improves the texture of the soil.

(v) Manure is prepared by the decomposition of dead plant and animal matter.

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

B
(v) only

C
(ii), (iii), (iv) and (v) only

D
(ii) and (iii) only

Solution

Manures are organic substances that supply almost all the nutrient elements required by plants and are obtained from dead and decaying organic matter. Manures enhance the water holding capacity of soil, increase the number of friendly microbes and improve the texture of the soil.
Question 5
1 / -0

Read the following statements and select the correct option.

Statement 1: Pheromones are used as biological method to control pest.

Statement 2: Pheromones lure adult male insects into special traps and prevent them from breeding.

A
Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.

B
Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.

C
Statement 1 is true but statement 2 is false.

D
Both statements 1 and 2 are false.

Question 6

1 / -0

Following are given the differences between manures and fertilisers. Which of the given differences are incorrect?

	Manures	Fertilisers
(i)	They are not soluble in water. So they are not easily absorbed by the roots of the plants.	They are soluble in water and are absorbed by the plants easily.
(ii)	These are inorganic substances.	These are organic substances.
(iii)	Excessive use does not harm the soil texture, they provide humus to the soil.	Excessive use can change the chemical composition of the soil and also pollutes water.
(iv)	They restore the soil texture and help in water retention.	They may damage the soil texture.
(v)	These are nutrient specific.	These are not nutrient specific.

Question 7
1 / -0

Pick the odd one out from each series given below and select the correct option.

(i) Chain pump, Dhekli, Drip system, Pulley system

(ii) Urea, Oxychloride, Potash, Ammonium sulphate

(iii) Khurpi, Weedicides, Seed drill, Silos

(iv) Sowing, Irrigation, Hybridisation, Harvesting

(v) 2, 4-D, MCPA, Butachlor, BHC

D

(i) (ii) (iii) (iv) (v)

Dhekli Urea Silos Harvesting Butachlor

Solution

Chain pump, dhekli and pulley system are traditional methods of irrigation while drip system is the modern method of irrigation. Urea, potash, ammonium sulphate are fertilisers while oxychloride is not a fertiliser. Khurpi, weedicides and seed drill are used in weeding while silos are used in storing food grains. Sowing, irrigation and harvesting are agricultural practices while hybridisation is not. 2, 4 - D, MCPA and butachlor are herbicides while BHC is an insecticide.
