Show answer
Correct Option: B
Explanation:
A Shade net house is a structure made from Hot dip galvanized Steel Pipe with quick couplings and enclosed by Agro nets or Anti Insect net to allow required sunlight, moisture and air to pass through the gaps. The plants that can be grown are:
1)Tomato
2)Seedless cucumber
3)Lettuce
So, the correct answer is 'Option B) Tomato'.

Slash and burn agriculture is

evs modern agriculture agricultural practices in india different types of farming and agriculture various agricultural practices

  1. Crop rotation

  2. Organic farming

  3. Jhum cultivation

  4. Step farming

Show answer
Correct Option: C
Explanation:

Slash and burn agriculture is also called as jhum cultivation. It is the process of growing crops in which the land of trees and vegetation are first cleared and then burned thereafter. The burnt soil contains potash which increases the nutrient value of the soil.

Thus, the correct answer is 'Jhum cultivation.'

In which of the following farming method polythene is used to cover crop plants?

evs modern agriculture agricultural practices in india different types of farming and agriculture various agricultural practices

  1. Polyhouse farming

  2. Precision farming

  3. Organic farming

  4. Mixed farming

Show answer
Correct Option: A
Explanation:

The protection of cultivated crop is known as polyhouse farming. In this method, polyethene plastic is used to cover the crops and protect from damage or harms. It is the process which crops extend their lifecycle and production can be done throughout the year.

So, the correct option is 'Polyhouse farming'.

Which of the following can be cultivated in polyhouse farming?

evs modern agriculture agricultural practices in india different types of farming and agriculture various agricultural practices

  1. Capsicum

  2. Potato

  3. Chilly

  4. All of the above

Show answer
Correct Option: A
Explanation:

Polyhouse also known as polytunnels (tunnels made of polyethylene) can be used to provide a higher temperature and humidity than that which is available in the environment but can also protect crops from intense heat, bright sunlight, winds, and hailstones. Capsicum is basically a cool season crop and day temperature less than 30$^o$ celsius is favorable for growth and yield. It can be grown in a polyhouse.

Which of the following statements is not correct regarding jhum cultivation ?

evs modern agriculture agricultural practices in india different types of farming and agriculture various agricultural practices

  1. It is also called as shifting cultivation and has resulted in deforestation.

  2. It helps in increasing crop yield to a considerable extent.

  3. A time-gap of several years is required for the recovery of the land after cultivation.

  4. It involves cutting down of trees of the forest, burning of the plant remains and then using the land for farming.

Show answer
Correct Option: B
Explanation:

Jhum cultivation which is popularly known as shifting cultivation is one of the oldest types of cultivation practices in India and is practised majorly in the northeastern states of India. This cultivation has a particular pattern that has to be followed according to the cycle or the period of Jhum cultivation.

Initially, the vegetation or the forest on the land is cleared where the cultivation needs to be practised and then the farming begins. After the harvest, the land is allowed to have its vegetation back.
Based on the above jhum cultivation will not help in increasing crop yield to a considerable extent.
So, the correct answer is 'It helps in increasing crop yield to a considerable extent.'

WhIch of the following is necessary for Improvement of the quality of crops?
1. Introduction
2. Hybridisation
3. Selection
4. Segregation

evs modern agriculture agricultural practices in india different types of farming and agriculture various agricultural practices

  1. 1, 2 and 3

  2. 1, 2, 3 and 4

  3. 2, 3 and 4

  4. 2 and 3

Show answer
Correct Option: A
Explanation:
Development of the new variety of plant processing desirable characters from existing ones is known as plant breeding.
Plant introduction means introducing a plant having desirable characters which are a genetic improvement, high yield, disease resistance and vigorous growth from a region of a country where growth naturally to a region or a country where does not occur earlier.
Then the pure line selection is done.
Hybridization is a method of reducing new crop varieties in which two or more plants of unlike genetical constituents are fused together.

So, the correct option is '1, 2 and 3'



Shifting cultivators normally grow

  1. Cash crops along with fodder

  2. The major crop along with cereals

  3. A single crop which is mainly consumed

  4. Grains, vegetable and tubers in rotation

Show answer
Correct Option: D
Explanation:
Shifting cultivation is an agricultural system in which a person uses a piece of land, only to abandon or alter the initial use a short time later. This system often involves clearing of a piece of land followed by several years of wood harvesting or farming until the soil loses fertility. Once the land becomes inadequate for crop production, it is left to be reclaimed by natural vegetation, or sometimes converted to a different long term cyclical farming practice. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the field is overrun by weeds. The length of time that a field is cultivated is usually shorter than the period over which the land is allowed to regenerate by lying fallow. Most families grow for subsistence purposes, just to eat and live. In other cases, the crops grown by each village vary by local customs and taste. The predominant crops include rice, maize (corn) and manioc and sorghum in Africa. Yams, sugarcane, plantain, and vegetables are also grown in some regions. 
So the correct option is 'grains, vegetable and tubers in rotation'.
