B. The size of the farm is too large.
C. Variety of crops are grown with livestock.
D. Entire operations of cultivation are mechanised.

Choose the correct answer from the options given below:

A, B and D only

The correct answer is Option (2) → A, B and D only

Extensive Commercial Grain Cultivation Commercial grain cultivation is practised in the interior parts of semi-arid lands of the midlatitudes (A). Wheat is the principal crop, though other crops like corn, barley, oats and rye are also grown (C is incorrect). The size of the farm is very large (B), therefore entire operations of cultivation from ploughing to harvesting are mechanised (D). There is low yield per acre but high yield per person. This type of agriculture is best developed in Eurasian steppes, the Canadian and American Prairies, the Pampas of Argentina, the Velds of South Africa, the Australian Downs and the Canterbury Plains of New Zealand.
