Question

Give reasons.
Different crops are grown in different regions.

Answer 1

Hint:Agriculture is an economic activity concerned with growing crops and rearing livestock. Crops are plants and plant products which are produced either for profit or for subsistence. Crops can be classified into food crops, feed crops, fiber crops, oil crops, ornamental crops and industrial crops.

Complete answer:Different crops grow in different regions because different geographical factors support different kinds of crops. Soil, climate , topography , rainfall influence the agriculture of any area and as these factors are different in different regions, crops grown are different too.

Soil : Soil is the material which is a mixture of water, gas, organic matter and minerals. Soils can be further classified into black soil, alluvial soil, laterite soil, marshy soil etc. Different soil supports different crops. For example, black soil is excellent to grow to grow cotton whereas arid soils can grow crops like barley and millet.

Topography : Relief of an area influences the agriculture of that area too. Topography determines levels of soil erosion, ease of tilling the land and mechanization of farms. For example crops like tea , coffee and rubber grow better in slightly hilly topography.

Climate : Crops do not grow well in extreme climates. Different kinds of climates are conducive for growing different kinds of crops. For example rice requires hot and humid climate, pigeon pea and sugarcane grow in tropical and subtropical climates, and potatoes grow in cool and temperate climates.

Rainfall : Levels of precipitation is important in determining the crops that are grown as rainfall is still a major source of irrigation in many parts of the world. Crops like millet require 25-75cm rainfall whereas rice requires 100-150cm rainfall.

Apart from geographical factors, human factors also determine which crops grow in which regions.
For example, areas where labour is cheap and easily available, labour intensive crops like paddy and sugarcane are grown. Areas which are closer to market grow easily perishable crops. Market gardening and horticulture is practiced in areas closer to urban spaces which have consumers from higher income groups.
Political aid is also important in influencing the crops that are grown in the region. State led Green revolution helped to boost the growth of paddy and wheat in areas of Punjab and Haryana.

Note:We can further elaborate on the point that different crops are grown in different regions by stating examples from India itself. Rice is grown in north eastern states and coastal areas, wheat is grown in Ganga-Satluj plains of the north and black soil region of Deccan plateau, millets are grown in areas of Rajasthan and Gujarat etc.
