3
Q
Rice:
Puddles or Wet Method
A
- Assured supply of water
- Land is ploughed
- Filled with 3 to 5 cm of standing water
- Mantained at 2 to 3 cm ⇒ Till seedlings are estalished
4
Q
Rice:
Sowing
A
- Broadcasting:
- Drilling:
- Dibbling:
5
Q
Rice:
Broadcasting:
A
- After ploughing the field
- Seeds are scattered by hands
- Before onset of Monsoon
- Followed in areas where:
- Labor is scarce
- Soil is infertile
6
Q
Rice:
- Drilling:
A
- Meaning:
- Seeds are sown in
- Furrows
- With the help of a drill
- Made of Bamboo
- Followed in:
- Peninsular India
7
Q
Rice:
Drilling
Advantage:
A
- Seeds fall in a sytematic way in the furrows
- Germination rate of seeds is high
- Wastage of seeds is minimal
8
Q
Rice:
Drilling:
Disadvantage:
A
- Time consuming
9
Q
Rice:
Dibbling:
A
- Dibble is an implement for making holes in ground for seeds or plants
- Seeds are sown at regular intervas in furrows, by hand
10
Q
Rice:
Transplanting:
A
- Seedling ⇒
- First grown in nurseries.
- Transplanted to fields after
- 25 to 30 cm (4 to 5 weeks)
- Transplanted at
- Groups of
- 4 to 6
- At Distance of
- 30 to 45 cm.
- Groups of
- Depth of water; 2 to 3, 4 to 6 till crop matures
11
Q
Rice:
Transplanting:
Places:
A
- Common in deltaic and flood plain
- Labour intensive
12
Q
Rice:
Tranplanting:
Advantage:
A
- Higher yield
- Only healthy plants are picked for resowing
- Removal of Unhealthy plants
- Weeds are removed while resowing
- Less wastage of seeds
- Compared to Broadcasting
13
Q
Rice:
Tranplanting (Japan):
A
- Improved in
- 1953
- HYV seeds called Japonica is used
- Seedlings are first grown in nurseries
- The distance:
- Rows of Plants: 25 cm
- Distance between the plants: 15 cm
14
Q
Rice:
Transplanting (japanese):
Higher Yield:
A
- Manure is used extensively
- Japonica seeds gives a higher yield
15
Q
Rice:
Harvesting:
A
- Before Harvesting:
- Fields are drained dry
- Traditional Cutting of the stalk:
- Sickle is used
- Labour Intensive
- Each Stalk is Hand Reaped
- Cut 60cm below the grain (facilitate threshing)
16
Q
Rice:
Processing:
A
- Mositure Content:
- Threshing:
- Winnowing
- Milling
17
Q
Rice:
Processing:
Moisture content:
A
- by drying the stalks in sun
18
Q
Rice:
Processing:
Threshing:
A
- Grains are seperated from the stalks
- Beating the sheaves against the wooden bars.
- It is done in rice fields
- To reduce Transportation costs
19
Q
Rice:
Processing:
Winnowing:
A
- Unwanted Husk is removed from the Grains
- Pouring the grains on a windy day. Chaff is blown aside. Grain fall to the ground.
20
Q
Rice:
Processing:
Milling:
A
- To remove the yellowish husk from the grains.
