Farm System
Agriculture or farming can be looked
at as a system. The important input
are seeds, fertilisers, machinery and
labour. Some of the operations involved
are ploughing, sowing, irrigation,
weeding and harvesting. The outputs
from the system include crops, wool,
diary and poultry products.

Types Of Farming
Primitive Subsistence Farming
This type of farming is still practised in few pockets of India.
Primitive subsistence agriculture is practised on small patches of
land with the help of primitive tools like hoe, dao and digging
sticks, and family/community labour. This type of farming
depends upon monsoon, natural fertility of the soil and
suitability of other environmental conditions to the crops grown.
It is a ‘slash and burn’ agriculture. Farmers clear a patch of
land and produce cereals and other food crops to sustain their
family. When the soil fertility decreases, the farmers shift and
clear a fresh patch of land for cultivation. This type of
shifting allows Nature to replenish the fertility of the soil
through natural processes; land productivity in this type of
agriculture is low as the farmer does not use fertilisers or other
modern inputs. It is known by different names in different parts
of the country.

Intensive Subsistence Farming
This type of farming is practised in areas of
high population pressure on land. It is labour
intensive farming, where high doses of
biochemical inputs and irrigation are used
for obtaining higher production.
Though the ‘right of inheritance’ leading to the
division of land among successive generations
has rendered land-holding size uneconomical,
the farmers continue to take maximum output
from the limited land in the absence of
alternative source of livelihood. Thus, there is
enormous pressure on agricultural land.

Commercial Farming
The main characteristic of this type of
farming is the use of higher doses of modern
inputs, e.g.
high yielding variety (HYV) seeds,
chemical fertilisers, insecticides and
pesticides in order to
obtain higher productivity. The degree of
commercialisation of agriculture varies from
one region
to another. For example, rice is a
commercial crop in Haryana and Punjab,
but in Orissa, it is a
subsistence crop.

Plantation
Plantation is also a type of commercial farming. In
this type of farming, a single crop is grown on
a large area. The plantation has an interface of
agriculture and industry. Plantations cover large
tracts of land, using capital intensive inputs, with
the help of migrant labourers. All the produce is
used as raw material in respective industries. In
India, tea, coffee, rubber, sugarcane, banana,
etc.. are important plantation crops. Tea in Assam
and North Bengal coffee in Karnataka are some
of the important plantation crops grown in these
states. Since the production is mainly for market,
a well developed network of transport and
communication connecting the plantation areas,
processing industries and markets plays an
important role in the development of plantations.

Major crops
Rice: It is the staple food crop of a majority
of the people in India. Our country is the
second largest producer of rice in the
world after China. It is a kharif crop
which requires high temperature, (above
25°C) and high humidity with annual
rainfall above 100 cm. In the areas of less
rainfall, it grows with the help of
irrigation. Rice is grown in the plains of
north and north-eastern India, coastal
areas and the deltaic regions. Development
of dense network of canal irrigation and
tubewells have made it possible to grow rice
in areas of less rainfall such as
Punjab,Haryana and western Uttar
Pradesh and parts of Rajasthan.

Millets: Jowar, bajra and ragi are the important
millets grown in India. Though, these are known
as coarse grains, they have very high
nutritional value. For example, ragi is very
rich in iron, calcium, other micro nutrients and
roughage. Jowar is the third most important food
crop with respect to area and production. It is a
rain-fed crop mostly grown in the moist areas
which hardly needs irrigation. Maharashtra is the
largest producer of jowar followed by Karnataka,
Andhra Pradesh and Madhya Pradesh. Bajra
grows well on sandy soils and shallow black soil.
Rajasthan is the largest producer of bajra followed
by Uttar Pradesh, Maharashtra, Gujarat and
Haryana. Ragi is a crop of dry regions and
grows well on red, black, sandy, loamy and
shallow black soils. Karnataka is the largest
producer of ragi followed by Tamil Nadu.
Apart from these states,Himachal Pradesh,
Uttaranchal, Sikkim, Jharkhand and Arunachal
Pradesh are also important for the production of
ragi.

Cotton: India is believed to be the original home of the
cotton plant. Cotton is one of the main raw materials for
cotton textile industry. India is the third-largest producer
of cotton in the world.
Cotton grows well in drier parts of the black cotton soil of
the Deccan plateau. It requires high temperature, light
rainfall orirrigation, 210 frost-free days and bright
sunshine for its growth. It is a kharif crop and requires
6 to 8 months to mature. Major cotton-producing
states are – Maharashtra, Gujarat, Madhya Pradesh,
Karnataka, Andhra Pradesh, Tamil Nadu, Punjab,
Haryana and Uttar Pradesh.

Coffee: India produces about four per
cent of the world’s coffee production.
Indian coffee is known in the world for
its good quality. The Arabica variety
initially brought from Yemen is
produced in the country. This variety is
in great demand all over the world.
Intially its cultivation was introduced
on the Baba Budan Hills.

AGRICULTURAL
DEVELOPMENT
Agricultural development refers to efforts made
to increase farm production in order to meet
the growing demand of increasing population.
This can be achieved in many ways such as
increasing the cropped area, the number of
crops grown, improving irrigation facilities, use
of fertilisers and high yielding variety of seeds.
Mechanisation of agriculture is also another
aspect of agricultural development. The
ultimate aim of agricultural development is to
increase food secutiry.

FARM IN INDIA

Agriculture in India has a significant history.
Today, India ranks second worldwide in farm
output. Agriculture and allied sectors
like forestry andfisheries accounted for 16.6% of
the GDP in 2009, about 50% of the total
workforce.[1] The economic contribution of
agriculture to India's GDP is steadily declining
with the country's broad-based economic growth.
Still, agriculture is demographically the broadest
economic sector and plays a significant role in the
overall socio-economic fabric of India.

FARM IN USA
Agriculture is a major industry in
the United States and the country is a
net exporter of food. As of the last
census of agriculture in 2007, there
were 2.2 million farms, covering an
area of 922 million acres (3,730,000
km2), an average of 418 acres (1.69 km2)
per farm.
