Agricultural Practices in India

Tobacco is a classic cash crop - grown primarily for sale rather than subsistence. Other cash crops include cotton, sugarcane, and tea. Maize, rice, and wheat are primarily food crops (cereals) grown for direct consumption, though they can also be sold commercially.

Geographical factors affecting agriculture include physical features like land nature, climate, winds, rainfall, and topography. Government policies, regulations, and subsidies are socio-economic or political factors, not geographical ones. This question tests the distinction between natural and man-made influences.

Grapes: Italy is a leading producer (true). Oilseeds: India is among the top global producers (true). Millets: India is the world's largest producer (true). Coffee: Ethiopia is the origin, but Brazil and Vietnam are the leading producers by volume. Option D correctly matches 1, 2, and 3.

Rabi crops are sown in winter (October-December) and harvested in spring (March-May). Wheat, mustard, and gram are classic rabi crops. Maize is a kharif crop (sown in monsoon, harvested in autumn), making it the correct answer for 'not a rabi crop'.

Millets (like bajra, jowar, ragi) are primarily grown using dry farming techniques in India, especially in arid and semi-arid regions of Rajasthan, Maharashtra, Karnataka, and other states with low rainfall. These crops are well-adapted to drought conditions and require minimal irrigation. Dry farming relies on soil moisture conservation rather than irrigation, making millets ideal for such agricultural systems.

All three methods mentioned - iron plough, wooden plough, and bullock-drawn ploughing - are traditional and modern tools/techniques used for tilling soil to prepare it for cultivation. Tillage can be done with various tools and power sources.

The Yellow Revolution refers to the dramatic increase in oilseed production in India during the 1990s. It aimed to reduce India's dependence on imported edible oils and achieve self-sufficiency.

This is the correct situation for growing cotton. Cotton plants are usually grown at places having black soil and warm climate.

Coffee is Brazil's chief crop and the country has been the world's largest coffee producer for over 150 years. Brazil produces approximately one-third of the world's coffee supply. Cotton is more significant in the US and India, jute is primarily grown in Bangladesh and India, and tea production is centered in China, India, and Kenya.

Crop selection is the most critical initial requirement for dry farming as it determines which drought-resistant varieties can survive with minimal moisture. Shallow ploughing and texture development are secondary practices, while animal husbandry is unrelated to the core requirement.

India leads the world in rice cultivated area and ranks second in rice production after China. This reflects India's dominant position in global rice agriculture.

The Blue Revolution refers to the rapid growth of fish production in India through aquaculture development. It mirrors other color-coded agricultural revolutions like the Green Revolution.

Jaya and Ratna are released throughout the rice growing belts of India.

This is the correct answer. Mustard is a rabi crop.
