Three physical factors influencing the

 and influence the quality of food. Thus

 favorable climatic conditions are must for cultivation.

2.Soil: Soil is a crucial component of successful

 farming and is the primary source of the

 nutrients which we use to raise crops.

which one more useful for India?

ANSWER:-

Subsistence agriculture refers to the form 

of agriculture in which the prime focus of the

 Production of food should be in excess that

 it both satisfies the needs of the farmers family 

and the remaining shall help them earning as well.

 output and quantity thus helping in developing

 agriculture in an area.
