Test: Agriculture - Class 6 MCQ

The Green Revolution led to a remarkable increase in food production, particularly for staple crops like wheat and rice, by introducing new seed varieties and modern agricultural techniques. This shift helped to combat famine and improve food security in many developing countries.

Commercial farming aims to maximize profit by producing crops on a large scale, often using modern agricultural methods and technology. This approach allows farmers to meet market demands and yield significant economic returns.

Agriculture is fundamentally about cultivating soil and raising livestock to ensure a reliable food supply. Its practices are essential for food production, which supports various sectors, including cities and industries, making it a cornerstone of human civilization.

Cash crops are primarily grown for profit and serve as raw materials for industries, unlike food crops, which are grown for direct human or animal consumption. This distinction highlights the economic role of cash crops in global trade.

Subsistence farming is a small-scale agricultural practice aimed at producing enough food for the farmer's family or local community. It is prevalent in rural areas of developing countries where resources are limited.

High Yield Variety (HYV) seeds were a key component of the Green Revolution, which significantly increased food production in developing countries. The introduction of these seeds, along with modern agricultural practices, helped alleviate food shortages and improve nutrition.

Intensive subsistence farming often involves polyculture, where multiple crops are planted together to enhance biodiversity and maximize the use of available resources. This method can lead to healthier ecosystems and better resilience against pests.

Extensive subsistence farming typically results in lower yields compared to intensive methods but focuses on producing high-quality, healthier crops with minimal environmental impact. This practice is often seen in forested regions where land is cleared for farming.

Intensive farming focuses on maximizing output from small land areas through the use of advanced machines and technology. This method is often employed in densely populated regions where land is limited, allowing for efficient production of crops.

Plantation agriculture is defined by the large-scale cultivation of a single crop, such as rubber or sugarcane, primarily for profit. This method typically involves significant investment in capital and labor and is often conducted in tropical climates.

Traditional agriculture often relies on manual labor and basic tools, utilizing knowledge passed down through generations. This method is typically influenced by local environmental conditions and cultural practices, leading to varied agricultural outcomes.

The Canterbury Plains in New Zealand are known for intensive pig farming, where advanced agricultural techniques and high-density production methods are employed to maximize output from limited land.

Agricultural practices around the world are highly influenced by physical factors such as climate, soil quality, and landform. These factors determine which farming methods are most suitable for specific regions, leading to diverse agricultural systems globally.

Organic farming emphasizes the use of natural fertilizers and pesticides, aiming to produce healthier crops without the chemical residues often associated with conventional farming methods. This approach is increasingly popular among consumers seeking sustainable food options.

The introduction of new agricultural techniques, particularly during the Green Revolution, led to improved diets and reduced famine in developing countries. By increasing crop yields, these advancements helped secure food resources and enhance overall nutrition for populations at risk of food scarcity.

Shifting cultivation is a traditional farming technique where farmers clear forest land by cutting and burning trees. This practice allows them to use the ash as fertilizer for a limited time before moving on to a new plot, allowing the old land to regenerate.

Nomadic herding involves the movement of herdsmen and their livestock to find pastures. This practice is commonly found in arid and semi-arid regions, where water and grazing land are limited, making mobility essential for survival.

Modern agriculture employs scientific techniques and advanced technology, resulting in higher crop yields compared to traditional methods. This improvement allows for more efficient food production to meet the demands of growing populations.

Commercial farming is prevalent in the prairies of the US and Canada, where large fields are cultivated for profit. This type of farming utilizes modern agricultural techniques to maximize production efficiency.

Extensive farming is characterized by low input in terms of labor and capital over large land areas. This method is often seen in sparsely populated regions where land is abundant, allowing for farming with minimal investment.
