Agricultural Practices in India Questions

Multiple choice zoology biodiversity, classification and conservation levels of biodiversity environmental conservation and biodiversity biodiversity on earth and in india

Which one has the largest species variety in India?

  1. Potato

  2. Maize

  3. Wheat

  4. Rice
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Species diversity is the number of different species that are represented in a given community. In India, rice has the largest species diversity or variety. India has 6,000 species variety of rice. The number has greatly reduced from before. The commonest rice is basmati rice.

So, the correct answer is 'Rice'.

Greatest genetic diversity of crop plant is found in

  1. Central America

  2. Homelands

  3. South America

  4. India
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Diversity in crops is showcased as genetic and phenotypic characters. These include variety of  the size of seeds, branching pattern, height differences, flower color, fruiting time and flavor. Genetic diversity is the total number of genetic characteristics that make up the species and play a major role in modern plant breeding and the greatest diversity in crop plants is seen in the homelands.

Which one of the following has maximum genetic diversity in India?

  1. Teak

  2. Mango

  3. Wheat

  4. Tea
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

India is one of the twelve megadiversity regions of the world with 7.7 percent of genetic resources of the world. 

Western Ghats have wild relatives of a number of cultivated plants like banana, citrus, mango, pepper etc. 
Common mango (Mangifera indica) originated as alloploid and its native home was suggested as Eastern India, Assam to Burma or possibly further in the Malay region (Popenoe, 1920). 
Vavilov (1926) also suggested Indo-Burma region as the centre of origin of mango. Hence, mango shows maximum genetic diversity in India.

Which one of the following has maximum genetic diversity in India ?

  1. Tea

  2. Teak

  3. Mango

  4. Wheat
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

India is considered a center of origin for many crops, and wheat shows significant genetic diversity in the region. While mango also has high diversity, wheat is a classic example in agricultural biology curricula.

Multiple choice geography africa - location, political divisions and physical features cocoa cultivation in ghana study of africa africa

Full yield of the cacao plants can be expected only after ___________.

  1. 3 years

  2. 5 years

  3. 7 years

  4. 10 years
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The effect of six planting densities on cacao yield of a commercial hybrid mixture as well as the interaction of planting densities with the years were investigated. Crop data collected over a 14-year period (1977-1990) showed that it was possible to optimize the regional cacao yields by implementing high planting densities (2500 and 1736 trees ha-1). 

This was however only true for the first half of the crop period. In the second half, low planting density (1059 trees ha-1) attained the best yields. This change in the ranking of planting densities over the years confirmed the presence of density-year interaction. Alternatives to achieve high productivity in high planting density systems were presented and discussed.

Key words: Density-year interaction, high productivity and Theobroma cacao L
Multiple choice evs - i the environment and us damaging the forests deforestation and afforestation protecting our environment pollution of soil degradation of land

Planting of trees, shrubs and others in between crop plants for stabilisation of soil is

  1. Taungya

  2. Social forestry

  3. Production plantation

  4. Agroforestry
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Agroforestry is the planting of trees, shrubs, and others in between crop plants.
  • Advantages of agroforestry practices include Increased crop production and economic gain. Soil conservation and improved soil quality. Sequestration of atmospheric carbon.
  • Hence Planting of trees, shrubs, and others in between crop plants for stabilization of soil is Agroforestry.
  • So, the correct answer is 'Agroforestry'.
Multiple choice biology the soil soil erosion (geo) soil erosion, soil conservation and uses of soil soil erosion and conservation

Farm land tends to erode most rapidly when planted with

  1. Wheat

  2. Potato

  3. Saccharum

  4. Clover
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Farm land tends to erode more rapidly when continuously planted with sugarcane, as sugarcane requires high moisture and organic content. As the amount of moisture and organic content decreases the top layers of soil can be easily eroded by wind or water

So, the correct answer is 'Saccharum'

Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

Maximum alcohol production per hectare of crop is from

  1. Potato

  2. Sugracane

  3. Sugarbeet

  4. <p>Tapioca</p>
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The amount of alcohol production per hectare of given crop is:

Potato - 396 gallons

Sugarcane - 662 gallons

Sugarbeet - 714 gallons

Tapioca - 410 gallons

Hence, maximum alcohol production is by sugarbeet.

So, the correct answer is 'Sugarbeet'.

Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

The plant which is not a component of energy cropping is

  1. Sugarcane

  2. Sugarbeet

  3. <p>Tapioca</p>

  4. <p>Euphorbia</p>
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Energy cropping is the cultivation of those plants which can be harvested to produce ethanol or bioethanol that can be used as a biofuel. Energy crops include sugarcane, sugarbeet, cassava (Tapioca), wheat, maize etc. Euphorbia is not an energy crop. Instead, it is a petro-crop or petroleum plant because it produces latex that has long chain hydrocarbons. This latex can be converted into biofuels and used as a substitute for petrol and other fuels.
So, the correct answer is 'Euphorbia'.
Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

Which one of the following is being utilized as a source of biodiesel in the Indian countryside?

  1. Euphorbia

  2. Beetroot

  3. Sugracane

  4. Pongarnia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Jatropha is a member of the euphorbia family. One of its great selling points as a biofuel is the fact that growing it need not compete with the cultivation of food. The selling point as a bioenergy crop is that it grows in marginal, eroded land, and is resistant to drought.
