Test: Agriculture - 2 - UPSC

The correct option is Option D.

Roughly 37% of Earth's land is today employed for agricultural purposes, with about 11% used for growing crops and the remainder for pasture.

The exact protein content of fish depends on the species you select. In a 3-ounce serving size of the most common fin fish, you’ll get between 16 and 26 grams of protein.

The correct option is B.
China In the 2018/2019 crop year, China produced some 148.5 million metric tons of milled rice, a higher volume than any other country. India came in second place with 116.42 million metric tons of milled rice in that crop year.

Reindeer herding is one of the forms of nomadic or shifting agriculture practised outside the tropics. 
Reindeer herding is limited to some areas only. A person who conduct reindeer herding is called reindeer herders and approximately 100,000 people are engaged in reindeer herding today around circumpolar north.

Genetically modified crops (GM crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species.

Poultry are farmed in great numbers with chickens being the most numerous. More than 50 billion chickens are raised annually as a source of food, for both their meat and their eggs. Chickens raised for eggs are usually called layers while chickens raised for meat are often called broilers.

Common staples include cereals (such as rice, wheat, maize, millet, and sorghum)

It's is true because due to low rainfall and less vegetation this grassland has converted into arid and dry land.

Salinization refers to a build up of salts in soil, eventually to toxic levels for plants. (3,000 - 6,000 ppm salt results in trouble for most cultivated plants.) Salt in soils decreases the osmotic potential of the soil so that plants can't take up water from it.

Introduction:

In this question, we need to determine which crop is not typically grown on a plantation.

Explanation:

We can analyze each crop and its characteristics to determine which one is not commonly grown on a plantation:

• Coffee: Coffee is commonly grown on plantations. Plantations dedicated to coffee production are known as coffee plantations.


• Rubber: Rubber is also grown on plantations. Plantations dedicated to rubber production are known as rubber plantations.


• Tea: Tea is another crop that is commonly grown on plantations. Plantations specifically established for tea cultivation are known as tea plantations.


• Sugar beet: Sugar beet is not typically grown on plantations. It is commonly cultivated in fields or farms rather than large-scale plantations.

Conclusion:

Based on the analysis, the crop that is not normally grown on a plantation is sugar beet (option D). Coffee, rubber, and tea are crops commonly grown on plantations.

• Raising fruit and vegetables: One of the primary activities in commercial horticulture is the cultivation of fruits and vegetables. This includes growing a wide variety of crops such as apples, oranges, tomatoes, lettuce, and more.


• Greenhouse production: Commercial horticulture often involves the use of greenhouses to extend the growing season and create ideal conditions for plant growth. Greenhouses provide controlled environments, allowing for year-round production.


• Plant propagation: Commercial horticulturists engage in plant propagation techniques to produce large quantities of plants. This may involve techniques like seed germination, cutting propagation, tissue culture, and grafting.


• Landscaping and ornamental plants: Many commercial horticulturists also specialize in growing ornamental plants, flowers, and shrubs for landscaping purposes. These plants are often sold to nurseries, garden centers, and landscapers.


• Marketing and distribution: Commercial horticulturists not only focus on plant production but also play a role in marketing and distributing their products. They may sell directly to consumers, wholesalers, retailers, or participate in farmers' markets and trade shows.


• Research and technology: The field of commercial horticulture is constantly evolving, with advancements in research and technology. This includes the development of new plant varieties, improved cultivation techniques, and the use of technology for irrigation, pest control, and monitoring plant health.

Sometime around 10,000-12,000 years ago, our hunter-gatherer ancestors began trying their hand at farming.
First, they grew wild varieties of crops like peas, lentils and barley and herded wild animals like goats and wild oxen. Centuries later, they switched to farming full time, breeding both animals and plants, creating new varieties and breeds. Eventually, they migrated outward, spreading farming to parts of Europe and Asia.

On July 6, 2009, Finance Minister Mr.Pranab Mukherjee announced the introduction of National Food Security Act under which BPL families in rural and urban areas will be entitled by law to 25 kg. of wheat or rice per month at Rs. 3 per kg.

Agriculture is probably the most significant activity that accelerates soil erosion because of the amount of land that is farmed and how much farming practices disturb the ground.

The time needed to form a soil depends on the latitude: in environments characterized by a mild climate, it takes 200-400 years to form 1 cm of soil. In wet tropical areas soil formation is faster, as it takes 200 years. In order to accumulate enough substances to make a soil fertile it takes 3000 years.

Arable farming involves growing crops such as wheat and barley rather than keeping animals or growing fruit and vegetables. Arable land is land that is used for arable farming

Agriculture (9.9 percent of 2018 greenhouse gas emissions) – Greenhouse gas emissions from agriculture come from livestock such as cows, agricultural soils, and rice production.
