Which of the following statements can be related to Jhoom farming?
-
The land is cleared by burning the weeds.
-
The burnt weeds increase the potash content of the soil.
-
The fertility of the soil increases.
-
All of the above.
Jhoom farming or cultivation is also known as slash and burn agriculture. It is practiced in the areas with thick forest such as Arunachal Pradesh, Meghalaya, Mizoram, etc. In this, a portion of forest is cleared by burning all the trees and weeds in that portion to produce ash. Burnt weeds increase the potash content of the soil and thereby increasing the fertility of the soil. Seeds are dropped on it and maize, chilies, rice, etc are grown.

More frequency of dominant genes
-
More diversity in improved variety

More favourable climatic condition

Net house farming is also called as

Greenhouse farming
-
Polyhouse farming
-
Polytunnel farming

Precision farming
- A net house refers to the structure which is enclosed by agro nets or any other woven material to allow required sunlight, moisture and air to pass through the gaps.
- It creates an appropriate microclimate conducive to the plant growth.
- These are also called as Shade house or a greenhouse.
- So the correct option is 'Greenhouse farming'.
The colour of net in net house farming is
-
White
-
Black
-
Green
-
None of the above
- Green shade nets allow many of the lights to pass through with minimal effect on photosynthesis, however the same is not true for all the colours.
- When the light passes through the shade nets, a fraction of light spectra gets reflected and that varies from the colour of light spectra.
- In blue shade nets, the photosynthetic activity gets reduced and in black/grey shade nets, shade avoidance mechanism is observed as the plant's photosynthetic activity does not suffice it.
- Therefore, green shade nets are mostly preferred over other coloured nets.
Which type of farming produces fertilizers?
