Concept:

While growing a crop, the steps followed are:

Explanation:

Onion cultivation:

• The soil is first ploughed deeply. 
• The right amount of seeds are dropped at a regular distance.
• It should be done carefully so as not to drop too many seeds in one place.
• After 20 days of sowing the seeds, they begin to sprout.
• Weeds start to appear along with the onion plants.
• Weeds need to be removed so that they do not take up all the water and fertilisers.
• If there are too many weeds, then the onion plants will not be healthy.
• The plants grow tall.
• The leaves start turning yellow and drying up.
• This means that the onions are ready to be taken out.
• The onions are now taken out.
• It is important that this should be done at the right time.
• If late, the onions will rot in the ground itself and all the hard work will be wasted.
• The dried leaves from the top of the onions are cut.
• The sacks are filled with onions and taken in a truck to sell in the big market.

Thus, the correct way of doing it -

(B) Digging to loosen the soil

(C) Sowing of seeds

(A) Weeding

(E) Plucking it out.

(D) Cutting the dried leaves from the top of the onion

Hence, the correct sequence is (B), (C), (A), (E), (D)

Concept

• Wheat is a grass that is widely grown for its seed.
• It is a cereal grain that is a typical diet worldwide.
• The genus Triticum is made up of numerous kinds of wheat.
• It is a significant source of carbohydrates.
• It has a protein level of roughly 13%.
• Wheat needs loamy oil and low rainfall.

Explanation

Yellow Soil:

• It is a part of the “omnibus group.”
• It covers about 18.5 % of the land area of the country.
• It is found in regions of low rainfall.
• This soil is also present in parts of Odisha and Chattisgarh
• In the southern parts of the Middle Ganga Plain.
• It is also called red and yellow soil.
• The soil is red due to the presence of iron in crystalline and metamorphic rocks.
• It appears yellow when hydrated and is called yellow soil.
• The fine-grained yellow soil is usually fertile.
• while the coarse-grained soil is less fertile.
• This soil type is generally deficient in nitrogen, phosphorus,s, and hummus.
• Wheat, cotton, oilseeds, millets, tobacco, and pulses are mainly cultivated in this soil.

Thus, wheat grows well in yellow soil.

Additional Information

Black Soil 

• Black soil is also known as “Regur Soil” or “Black Cotton Soil.”
• It covers about 15% of the country's total land area.
• It covers most of the Deccan Plateau.
• The color of these soils varies from deep black to grey.

Alluvial Soil:

• Alluvial soils are widespread in the northern plains and river valleys.
• It covers about 40% of the land area of the country. 
• These soils are mainly derived from the debris brought down from the Himalayas.
• They are also found in deltas and river valleys.

Concept:

Crop:

• A crop is a cultivated plant produced economically on a big scale and harvested frequently for income or food.

Farming:

• Agriculture is a primary activity. 
• It includes growing crops, fruits, vegetables, flowers and rearing livestock.
• In the world, 50 per cent of people are engaged in agricultural activity.

Explanation:

Peas cultivation:

• It is a crop that is grown in cool climates all over the world.
• Dried peas are used as a pulse, whereas green pods are utilised as a vegetable.
• Loamy soil that drains well and has a pH range of 6-7.5 is ideal.
• The optimal range for flowering and pod germination is 12–15 °C.
• The world's largest producer of green peas is the mainland of China.

Thus, China is the largest producer of green peas in the world.

Additional InformationCrop production:

The correct answer is Cotton and paddy. Key Points

• Kharif crops are those crops that are sown in the rainy season and harvested in the winter season.
• They require high rainfall and warm temperature for their growth.
• Cotton and paddy are two major Kharif crops that are widely grown in India.

Additional Information

• Maize and peas are not Kharif crops.
• Maize is a summer crop, while peas are grown in both Kharif and Rabi seasons.
• Barley and gram are Rabi crops.
• These are sown in the winter season and harvested in the summer season.
• Mustard is also a Rabi crop.
• It is grown in the winter season.

The correct answer is Only (A) is true.

Key Points

India is believed to be the original home of the cotton plant.

• Cotton is one of the main raw materials for cotton textile industry.
• In 2008 India was second largest producer of cotton after China.
• Cotton grows well in drier parts of the black cotton soil of the Deccan plateau. Thus, statement C is incorrect.
• It requires high temperature, light rainfall or irrigation, 210 frost-free days and bright sun-shine for its growth. Thus, statement B is incorrect and statement A is correct.
• It is a kharif crop and requires 6 to 8 months to mature.
• Major cotton-producing states are– Maharashtra, Gujarat, Madhya Pradesh, Karnataka, Andhra Pradesh, Telangana, Tamil Nadu, Punjab, Haryana and Uttar Pradesh.

The correct answer is Rice.Key Points

• Kharif crops are those crops which are sown in the rainy season and harvested in the winter season.
• Rice is a classic example of a Kharif crop. 
• Wheat, on the other hand, is a Rabi crop which is sown in the winter season and harvested in the summer season.
• Barley is also a Rabi crop which is sown in the winter season and harvested in the summer season.
• Mustard is a crop which is grown in both the Rabi and Kharif seasons depending on the region and climatic conditions.
• Rice is the main Kharif crop grown in India and is an important staple food for millions of people.

Additional Information

• Wheat is the second most important cereal crop after rice and is grown extensively in the northern and central parts of India.
• Barley is an important crop in the hilly regions of India and is used for both human consumption and animal feed. 
• Mustard is an oilseed crop which is grown in the northern and eastern parts of India and is used for making cooking oil and as a condiment.
• It is important to choose the right crop for a particular season and region as it can affect the yield and productivity of the crop.

Fibre Crops:

• Cotton, jute, hemp and natural silk are the four major fibre crops grown in India.
• Cotton and jute are examples of fibres obtained from plants.

Explanation:

Cotton:

• Cotton is one of the main raw materials for the cotton textile industry.
• Cotton grows well in drier parts of the black cotton soil of the Deccan plateau.

The correct answer is Pulses.

Key Points

• Pulses, also known as legumes, are the edible seeds of leguminous plants cultivated for food.
• Leguminous crops are those which belong to the pea family (Leguminosae).
• The majority of plants in this family have root nodules that are home to rhizobium bacteria, which fix nitrogen from the air.
• This fixed nitrogen can raise the amount of nitrogen in the soil when plant leftovers break down.
• To increase soil fertility, legumes are frequently grown as a relay crop or in close proximity to maize, millet, and rice.
• In areas with a well-established dairy sector, fodder legumes are suitable alternatives.

The correct answer is Fungus

Key Points

• Rice blast caused by fungus Magnaporthe Oryzae, is generally considered the most important disease of rice worldwide because of its extensive distribution and destructiveness under favorable conditions
• Rice blast can affect most of the rice plants with the exception of the roots.
• The fungus can infect plants at any growth stage.
• The pathogen infects and produces lesions on the following parts of the rice plant: leaf (leaf blast), leaf collar (collar blast), culm, culm nodes, panicle neck node (neck rot), and panicle (panicle blast)

The correct answer is rice.
