Cropping system= Cropping pattern + Management
Cropping system is an important component of a farming
system
It represents the cropping patterns used on a farm and their
interaction with farm resources
Cropping pattern means the proportion of area under various
crops at a point of time in a unit area
It indicate the yearly sequence and spatial arrangement of
crops and fallow in an area
Crop sequence and crop rotation are generally used
What is cropping system

6. 6
Type of cropping system:
Depending on the resources and technology available, different
type
of cropping systems are adopted on farm which are given below.
1- Mono cropping or Single cropping
2- Multiple cropping or Poly cropping
3- Intercropping
4- Mixed cropping
5- Relay cropping
6- Sequence cropping



1- Mono cropping or Single cropping:
Mono-cropping refers to growing only one crop on a particular
land
year after year.
Or Practice of growing only one crop in a piece of land year
after
year e.g. growing only wheat crop in every year.
This is due to climatologically and socio economic

Q.No.1 Growing only one crop on a particular
land year after year is knows as..
1 Mono cropping
2- Multiple cropping
3- Intercropping
4- Mixed cropping
7

8.  E.g. Groundnut or cotton or sorghum is grown every year
due to limitation of rainfall.
Tobacco is grown in Günter (A.P.) due to specialization of
a farmer in growing a particular crop. Rice crop is grown,
as it is not possible to grow any other area where enough
water is not available.
•
•
•
•
•
2- Multiple cropping or Poly cropping:
It is a cropping system where two or three crops are gown annually
on the same piece of land using high input without affecting basic
fertility of the soil.
Growing two or more crops on the same piece of land in one
calendar year known as multiple cropping.
It includes inter-cropping, mixed cropping and sequence cropping.
e.g: Tomatoes + Onions + Marigold

9. 9

10. Molested (1954) has mention that multiple cropping is a
philosophy of maximum crop production per acre of land with
minimum soil deterioration. E.g. rice, potato, Green gram


3- Intercropping:
Intercropping is growing two or more crops simultaneously on
the same piece of land with a definite row pattern
e.g. growing of Setaria + Red gram in 5:1 ratio, it means after
every 5 rows of Setaria, 1 rows of Red gram is sown.
or wheat + mustard 9:1.
For successful intercropping, there are certain important
requirement.
1- The time of peak nutrient demands of components should
not overlap. In Maize + Green gram intercropping system, the
peak nutrient demand for green gram is around 35 DAS while
in maize it is 50 DAS.
10

11. Mixed cropping
•
•
Growing of two or more than two crop simultaneously on
same piece of land without any definite row pattern or
any fix ratio is known as Mixed cropping.
First of all the scientific study about mixed cropping was
done by (La Flitze, 1928).
11
2-Competition for light should be minimum among the
component crop.
3- The differences in maturity of component crop should
be at least 30 days

12. 4-Relay cropping
12
•
•
•
This form of intercropping is where second crop
planted before harvesting of first crop.
The term actually means an overlapping of growth
periods of two or more crops on the same piece of
land in a 12-month period.
A second crop is usually planted after the first
crop has reached its reproductive stage of growth
but before it is ready for harvest.

Q.No.2 Growing of two or more than two crop
simultaneously on same piece of land without any
definite row pattern or any fix ratio is known as …..
1 Mono cropping
2- Multiple cropping

14. 5- Sequence crop
•
•
•
Defined as growing of two or more crops in
sequence on the same piece of land in a farming
year.
Crop intensification is only in time dimension and
there is no intercrop competition.
Depending on the number of crops grown in a
year. It is called as double, triple and quadruple
cropping involving two, three, and four crops,
respectively.
E.g. Double cropping: 1-Rice – potato/ mustard 2.
Sorghum- gram.
14

15. (D)Multistoried cropping: Cultivation of crops of different
heights in the same field at the sametime. e.g. Sugarcane
+ Indian bean or potato or onion, Sorghum+ mung
(E) Ratoon cropping: Raising a crop with re-growth
coming out of roots or stalks after harvest of the crop. e.g.
sugarcane, tur, fodder sorghum, fodder maize. This
minimizes the cost of production of next crop in terms of
land preparation and cost
of seed, also the next crop i.e. ratoon crop gets already
established root system.

16. Q.No.2 Raising a crop with re-growth coming out
of roots or stalks after harvest of the crop is
called
A) Ratoon cropping
B) Multistoried cropping
C) Sequential cropping
D) Intercropping

Allied enterprises



In an integrated farming system, it is always emphasized
to combine cropping with other enterprises/activities.
Many enterprises are available and these primarily include
dairying, sheep & goat rearing, poultry, fisheries, sericulture,
bee keeping etc.
Any one or more can be combined with the cropping
system.

18. Allied enterprises




Agriculture and allied activities support livelihood of nearly
70 % India's rural population.
In recent year, small and marginal farmers are increasingly
becoming unsustainable, since their land are not able to
support the family’s food requirement and fodder for their
cattle.
As a result, rural households are force to look at alternative
means for supplementing their livelihoods.
In this context, rural resource based micro enterprises have
emerged as alternative livelihood opportunity in rural areas.

19. 1. Dairying




Dairy farming is one of the economically viable enterprises
that could provide constant income throughout the year to
farmers when combined with cropping.
The success of dairying depends solely on the availability of
inputs like feed and fodder and better marketing facilities to
milk.
To maximize benefits from dairying selection of proper breed
to suit the local conditions is very essential.
The dairy cattle are broadly classified into the following 5
groups.

Draft breeds: The bullocks of these breeds are good
draft animals, but the cows are poor milkers e.g,
Nagore, Hallikar, Kangeyam, Mali.
Dairy breeds: The cows are high milk yielders and the
bullocks are with good draft work capacity e.g.,
Sahiwal, Sindhi, Gir.
Dual Purpose: The cows are fairly good yielders of
and the bullocks are with good draft work capacity e.
g., Haryana, Ongole and Kankrej.
Exotic breeds: The exotic breeds are high milk
yielders, e.g., Jersey, Holstein-Friesian, Ayeryshire,
Brown Swiss and Guernsey
Buffaloes: Important dairy breeds of buffalo are
Murrah, Nili Ravi (Which has its home tract in
Pakistan), Mehsana, Surti, Zafarabadi, Godavari and
Bhadawari.


Biogas plant is a system comprising of a gas-holder and
a digestion chamber, in which “Gobar” (or cow dung)
can be treated anaerobically to produce two important
and useful items viz., fuel gas (or biogas) and organic
manure.
In this biochemical process the cellulosic material are
broken down to methane and carbon-dioxide by different
groups of microorganisms.
It is a clean, unpolluted and cheap source of energy,
which can be obtained by a simple mechanism and little
investment.
India was the first country in the world to have
developed a biogas plant on an experimental basis as
early as 1939.
22

24. 
1. Float dome type: Different models are
available in this category, e.g., KVIC vertical
and horizontal, Pragati model & Ganesh
Model.
2. Fixed dome type: The gas plant is dome
shaped under ground construction. The
entire construction is made of bricks and
cement. The models available in this category
are Janta and Deen-Bandhu.
The selection of a particular type depends on
technical, climatological, geographical and
economic factors.



Biogas is composed mainly of methane (55 –
60%) and Carbon Dioxide (35 – 45%).
Hydrogen and hydrogen sulphide can also be
present in small amounts.
Gas production would be maximum at a
temperature between 30-35oC.
27
Technical information

28. 




The site of biogas plant should be close to the kitchen
and cattle shed to reduce the cost on gas distribution
system and transportation of cattle dung.
Land should be leveled and slightly above the ground
level to avoid inflow or run-off of water.
Biogas plant should get clear Sunshine during most part
of the day.
Gas generation is a function of dung availability.
The amount of gas production is considerably higher in
summer followed by rainy and winter seasons.

Site selection and management:

29. 


It can be efficiently used for domestic cooking and lighting.
It can also be a used as a substitute fuel for running diesel
engine.
It does not emit smoke like other conventional forms of fuel
viz., coal, fire-wood and kerosene.
29
Uses of biogas and slurry:



Slurry is obtained after the production of bio-gas.
It is enriched manure containing NPK and humus.
Another positive aspect of this manure is that even after
weeks of exposure to the atmosphere, the slurry does not
attract fleas and worms.

Rearing sheep and goat is one of the important common
livestock enterprises followed in drought prone, hilly and
desert areas.
Goat farming needs less capital compared to dairying, and the
animals can be raised in small farms as well.
This enterprise provides employment opportunities round the
year for the farm household.
Not much financial inputs are required but steady income is
assured throughout the year.
Even with the poor grazing facilities and with minimum
managerial resources sheep and goats can return high profits
to farmers.
They not only help the household with regular cash flow but
also improve the health of family members by providing milk
and meat regularly.
Popular goat variety: Alpine, Sanen, Tellichery, Sirohi
Popular breeds of sheep is: [Lincoln, Merino, Dorset, Jacob 31


Poultry farming is emerging as an important livestock activity
in Farming system for enhancing economic stability, nutrition
and providing regular employment and cash flow.
Poultry meat accounts for about 27% of the total meat
consumed world wide, and its consumption is growing at an
average of 5% annually.
The average global consumption is 120 eggs per person/
year and in India it is 55 eggs per capita/year

Ponds serve various useful purposes, viz., domestic
requirement of water, supplementary irrigation source to
cropping and fisheries.
With the traditional management, farmers obtain
hardly 300-400 kg of wild and culture fish per ha annually.
However, poly-fish culture with the stocking density of
7500 fingerlings and supplementary feeding will boost
the total biomass production.

Pond: The depth of the pond should be 1.5-2.0 m. This depth will
help for effective photosynthesis and temperature maintenance
for the growth of zooplankton and photosynthesis. Clay soils have
higher water retention capacity and hence are best suited for fish
rearing.
Poly fish culture: The phytophagous fish (Catla, Rohu
and Mrigal) can be combined with omnivorous
(Common Carp), Plankton-feed (Silver Carp) and Mud-
eaters (Mrigal and Calbasu) in a composite fish culture
system. For example a combination of silver carp
(surface feeder), Mrigal (bottom feeder), rohu (column
feeder), and grass carp (specialized feeder on aquatic
plants) can be successfully used in the ratio of 4:3:2:1 in
poly fish culture.
Management: The fish are to be nourished through supplementary
feeding of rice bran, oil seed cakes and poultry excreta. This will
enable faster growth and better yield. This stocking density will
enable to get maximum yield of 2000 to 5000 kg/ha of fish annually.

The bee-keeper should be familiar with the source of
nectar and pollen within his locality.
The most important sources are nectar and pollen.
The sources of nectar are Tamarind, Mango, Guava
and most of the fruit crops.
Whereas the sources of pollen include crops such as
maize, sorghum & other millets, sunflower and palm tree.

The plants which will provide nectar and pollen for
honey bees are known as bee pasturages.
The bee keeping activity must begin with flowering
season.
The most suitable time for commencing bee keeping in
a locality is the arrival of the swarming season.
Swarming is a natural tendency of bees to divide their
colonies under conditions that are generally favorable

Sericulture is an agro-industry, the end product of
which is silk.
Sericulture involves the activities viz., Mulberry
cultivation, Silkworm rearing, Reeling the silk from the
cocoons formed by the worms.
The first two activities are basically agriculture in
nature and the later is an industry of different financial
investments.
India is the second largest producer of mulberry silk
after china.
