agriculture

Only (i)

Shifting cultivation is characterized by clearing forest patches (slash and burn), typically in tropical regions with high rainfall. It is a subsistence practice, not for market sale, making (iii) incorrect.

Cotton requires high temperatures, light rainfall or irrigation, 210 frost-free days, and bright sunshine for its growth. It is grown in the listed countries.

In developing countries with high population density, land is scarce relative to labor, necessitating intensive agriculture to maximize yield per unit area.

Large farm sizes (250 hectares), high mechanization, and satellite-linked precision farming are characteristic of commercial agriculture in developed nations like the USA.

Historically and in many textbook contexts regarding India's economy, approximately two-thirds of the population is engaged in agricultural activities.

Agro-based industries derive raw materials from agriculture (e.g., cotton, jute, sugar). Cement is a mineral-based industry.

Plantation agriculture is a type of commercial farming where a single crop (like tea, coffee, or rubber) is grown on a large estate.

Slash and burn farming involves clearing a patch of land, burning vegetation, and growing crops for subsistence.

The automotive industry is the largest consumer of natural and synthetic rubber, primarily for the production of tires and tubes.

India is the world's largest producer and consumer of pulses, which are a staple part of the Indian diet.

Castor seed is unique among major oilseeds in India as it can be grown in both the Rabi and Kharif seasons.

Punjab and Haryana are known for highly mechanized commercial grain farming, particularly wheat and rice, due to the Green Revolution.

Zaid is a short cropping season between Rabi and Kharif, typically used for growing water-rich crops like muskmelon, watermelon, and cucumber.

Primitive subsistence farming relies on natural factors like monsoon rains, natural soil fertility, and family labor rather than modern inputs like fertilizers or high-yield seeds.

The Minimum Support Price (MSP) is the rate at which the government buys crops from farmers to protect them against a sharp fall in farm prices. It ensures that farmers receive a guaranteed price for their produce.

Rice is a kharif crop that requires high temperatures (above 25 degrees Celsius) and high humidity with annual rainfall above 100 cm. Option A correctly identifies these climatic requirements.

Leguminous crops are plants that have nodules on their roots containing nitrogen-fixing bacteria. Pulses are the most common example of leguminous crops in India.

Uttar Pradesh is one of the largest producers of pulses in India due to its vast agricultural land and favorable climate for crops like gram and peas. Other states listed are not primary pulse producers.

Plantation agriculture is a type of commercial farming where a single crop is grown on a large scale. Tea, coffee, banana, and sugarcane are classic examples of plantation crops.

The three major cropping seasons in India are Rabi (winter), Kharif (monsoon), and Zaid (summer). These seasons are defined by the timing of sowing and harvesting.

Rice is the staple food crop for the majority of the population in the eastern and southern parts of India, where high rainfall and warm temperatures support its cultivation.

Non-food crops are those grown for industrial or commercial use rather than for direct human consumption. Cotton and jute are primary examples of fiber crops used in industry.

The Ganga-Sutlej plains in the northwest and the black soil region of the Deccan are the two main wheat-growing zones in India due to favorable soil and climate conditions.

Oilseeds are a significant part of Indian agriculture, covering approximately 12 percent of the total cropped area in the country.
