Q

they are the leaves of the embryo that provide nourishment to the developing plants

there are two types of this embryo leaf, the _______ & _____

A

cotyledons

monocots (monocotyledonous) & dicots (dicotyledonous)

22
Q

Give the 3 functions of a seed coat

A
  1. Protects the seed from mechanical or physical damage
  2. Prevents the seed to germinate even in favorable conditions
  3. Prevents excessive water-loss from the seeds
23
Q

Give the 2 functions of the seed endosperm

A
  1. Stores reserve food that provide nourishment to the developing plant
  2. Protects the embryo, by acting as a mechanical barrier
24
Q

Give the 2 functions of the seed embryo

A
  1. Gives rise to a complete new plant
  2. Stores food and provide nourishment to the new plant
25
Q

It is the art of placing seeds in the soil to have good germination in the field.

A

Sowing

26
Q

What are the 7 methods of sowing seeds?

A
  1. Broadcasting
  2. Dibbling
  3. Seed Dropping Behind the Plow
  4. Drilling
  5. Transplanting
  6. Hill Dropping
  7. Check Row Planting
27
Q

the method of random scattering of seeds on the surface of seedbed. It can be done manually or mechanically.

A

Broadcasting

28
Q

the process of placing seeds in holes made in the seedbed and closing the seed with soil. In this method, seeds are placed in holes made at definite depth at fixed spacing.

A

Dibbling

29
Q

Most vegetables are sown in this method.

A

Dibbling

30
Q

consists of dropping the seeds in furrow lines in a continuous stream and covering them with soil.

A

Drilling

31
Q

consists of rising the seedlings in a nursery bed and then planting the seedlings in another field (main field). It is commonly done for paddy, vegetable and flowers.

A

Transplanting

32
Q

In this method, few seeds are dropped as a hill at a fixed place and not in a continuous stream.

A

Hill Dropping

33
Q

It is a method of planting, in which row-to-row and plant-to-plant distance is uniform. In this method, seeds are planted precisely along straight parallel furrows.

A

Check Row Planting

34
Q

What type of film/mulch is used during rainy season?

A

Perforated Film

35
Q

What type of film/mulch is used in Orchards and Plantations?

A

Thicker Mulch

36
Q

What type of film/mulch is used when implementing soil solarization?

A

Transparent Film

37
Q

What type of film/mulch is used when controlling weeds through solarization?

A

Thin Transparent Film

38
Q

What type of film/mulch is used when implementing weed control in cropped land?

A

Black Film

39
Q

What type of film/mulch is used in sandy soil?

A

Black Film

40
Q

What type of film/mulch is used during saline water use?

A

Black Film

41
Q

What type of film/mulch is used in summer cropped land?

A

White Film

42
Q

What type of film/mulch is used as insect repellant?

A

Silver-colored Film

43
Q

What type of film/mulch is used during early germination?

A

Thinner film

44
Q

What are the important parameters to consider when choosing plastic film?

A
  1. Thickness
  2. Width
  3. Perforations
  4. Mulch Color
45
Q

Normally the _________ of the film does not affect the mulching effect except when it is used for colorization. But some of the recent references do indicate its impact on crop yield.

A

Thickness

46
Q

What is the normal width of the film that can adapt to different conditions?

A

One and a half meters.

47
Q

The ____________ of a film mulch may be advantageous under some situations and disadvantageous for some other situation.

A

Perforations

48
Q

The capillary movement of water and fertilizer distribution will be better
and more uniform under ___________ condition.

A

Imperforated Film

49
Q

Prevention of water stagnation around the plants, is better. But it has got the disadvantages of encouraging weed growth.

A

Perforated Film

50
Q

What factors does the color of the mulch affect?

A
  1. Soil temperature
  2. Air temperature around plants
  3. soil salinity
51
Q

Which color type of film deposits more salt on soil surface?

A

Transparent

52
Q

This color type of film restricts water movement and upward movement of salt is reduced.

A

Black Film
