Given below is the map of areas of Extensive Commercial Grain Farming. Analyse the maps and answer the following questions:

Which of the following is NOT true about Extensive commercial grain cultivation ?

Farming operations are manually done

The correct answer is Option 2: Farming operations are manually done

Option 1: The farm size are very large. : Extensive commercial grain cultivation is practised on very large farms, especially in countries like USA, Canada, and Australia, so this statement is correct.

Option 2: Farming operations are manually done : In extensive commercial grain cultivation, farming operations are highly mechanised and use machines such as tractors, harvesters, and combines, so this statement is not true.

Option 3: High yield per person : Due to the use of advanced machinery and modern technology, one person can manage a large area of land, resulting in high yield per person, so this statement is correct.

Option 4: Low yield per acre : Since cultivation is spread over vast areas with comparatively less intensive use of labour and inputs per unit area, yield per acre is relatively low, so this statement is correct.

NCERT: Commercial grain cultivation is practised in the interior parts of semi-arid lands of the mid-latitudes. Wheat is the principal crop, though other crops like corn, barley, oats and rye are also grown. The size of the farm is very large, therefore entire operations of cultivation from ploughing to harvesting are mechanised. There is low yield per acre but high yield per person.
