How many crops are grown in Dry farming?
A) 1
B) 2
C) 3
D) 4

Hint: Dry farming, also known as Dryland Farming, cultivation of non-irrigated crops in humidity-restricted areas, usually less than 20 inches (50 centimetres) of precipitation annually. Dry land agriculture occupies nearly 75% of cultivated area in india and produces 44% of required food.

Complete answer:
One crop at a time can be grown in dry farming. Dry Farming, also known as Dryland Farming, cultivation of non-irrigated crops in humidity-limited areas usually less than 50 centimetres (20 inches) of precipitation per year. Dry farming relies on the successful storage of the soil's limited moisture and the selection of crops and methods of growing that allow the best use of this moisture.

Typical methods are to till the land shortly after harvest to keep it free of weeds, but stubble is left in the fields after harvest to trap snow in certain latitudes. During crop growing, moisture management consists primarily of weed destruction and runoff prevention. The ideal soil surface is weed-free, but has ample clouds or dead vegetable matter to avoid erosion and prevent runoff.

Hence the correct answer is option ‘A’.

Note: Dry farming, an agricultural method implemented in areas with annual precipitation of about 15 to 20 inches. (38.1-50.8 cm) where irrigation is impractical, with most of the rainfall in spring and early summer. Dry-land crops must be either resistant to drought or evasive to drought. i.e. ripening in late spring or fall, sometimes using particular crop varieties such as wheat, barley, maize, sorghum, and rye.
