Definition, in Brief
Disclaimer:
All Definitions / terminologies explained are for the purpose of understanding and usage in crop
survey only. These definitions are NOT to be compared / correlated or interpreted with other
definitions that exists within the other Governmental programs, GO’s, text books or any other
reference material.
Definition / Terminology Description / Remarks
Crop
The word crop is used here to refer any plant / tree / shrub / herbs etc grown by a farmer on his/her land
parcel
Plantation
A group of tree / plants which are relatively permanent in nature which is grown and / or maintained or
operated by a farmer within a piece of land in defined pattern. Ex: Mango, Coconut, Cashew etc
Tree
A tall plant that can live for a long time. Trees have a thick wooden central part from which branches grow.
Long tree which has a longer life time without branches are also called trees (Ex: Cocount, palm etc)
Annual Crop A crop which has life period of around 1 year (ex: sugarcane, Banana etc)
Seasonal Crop
Crops which are grown by a farmer which has a life period of around 3 to 6 months time. Ex: Paddy,
Groundnut etc
Perennial Crop
Tree Crops within a defined boundary in defined pattern which are grown / maintained or operated by a
farmer which has a life period of around 3 to 6 months time. Ex: Paddy, Groundnut etc
Row / Border Crops
Tree crops which are grown / maintained or operated by a farmer which has a longer life period of more than
1 year which are grown in a land parcel - along the boundaries are inside in specific pattern or randomly.
Record of Rights- Tamil Nilam
The Record, typically maintained by the Revenue Department, containing information on who owns which land
parcel, land type, their extent of ownership of areas within the land parcel
Owner
A person who has the legal posession of a piece of land and whose name is recorded in the Record of Rights
(Tamil Nilam). Joint Owners or Multiple Owners are possible to be present in the RoR. In case of a joint
owner(s), the total extent of land is equally shared across all the owners. If the area of extent owned by a
owner is specifically recorded for a plot for a specific owner, then the extent mentioned against each owner
Farmer
Any person who does farming on a piece of land. Farmer can be an owner or legal heir owning or not owning a
land
Adangal
A registry of farmer and crop along with the survey numbers which is being maintained by the Revenue
department
Extent
Area owned by a owner or farmer. In crop survey all extent is recorded in Hectare and Are's. Ex: XX-XX.XX)
Note: 100 Are = 1 Hectare; 100 Sq metre = 1 Area
village map, FMB, Land Parcel
Land Parcel: Land Parcel is an piece of land area which is owned by an individual or an entity whose ownership
status is recorded in the Record of Rights
FMB: Field Measurement Book, a map with details of measurement of edges of each Land Parcel and its
location with asosciated reference station / reference line-edge along with adjacent land parcels reference.
Village map: is a map which shows the aggregated locations of all land parcels / FMB maps and associated
details of all land parcels of a village. These are the reference legal sketches used to identify a Land Parcel that
existed as on the date of creation of map.
Survey no, Subdivision No
Every FMB / Land Parcel map is uniquely numbered within a village, originally. These original numbers which
are sequential in nature are called Survey numbers. Further subdivisions of land are recorded with alphabets
and numbers and are uniquely numbered within a sub-divided polygons. These unique numbers within a
survey number is called sub-survey number. The concatenated value of survey number and subsurvey number
will be unique and are referred with for locating any sub-divided land parcel, uniquely. When a Village code is
concatenated with the survey number, then the reference to the land parcel is unique across the state.
Collabland
A Software developed by NIC which has a web and desktop version that is used by Revenue Survey and
Settlement department for creating the digital boundary / polygons for the FMB sketches
LGD Code
LGD refers to Local Government Directory. It is the registry of codes for various jurisdictional limits /
boundaries that exists in various government departments in the country which is maintained by Government
of India. The respective state departments that deifnes and maintains the jurisdictional boundary registers
these details in the GOI Portal wherein a unique number across the nation is provided for such entries - for
unique reference. GoI has mandated the use of these codes for exchange of data across ministries and the
states so that the entire country can adopt a common system which is very much useful for data exchange.
These LGD codes are unique with respect to Villages. Please note, area referred as villages by RDPR (Panchayat
Village) are different than the Villages referred by Revenue (Revenue Village).
In TN and in many other states, LGD codes are given and maintained by the Land Administration department -
which for the purpose of the land administration has divided one revenue village in to two or more and has
recorded unique LGD Code for such villages, uniquely and has recorded as Revenue Villages in the GoI
directory. However, the revenue survey maps that need to be existing along with every village are not updated.
ie. subdivided village maps are not prepared and hence, there exists a gap / confusion in referring the LGD
codes to the Revenue survey codes and associating the respective maps. These need to be resolved / Clarified
before starting the Crop Survey.
Irrigation source
Source of Water to the respective farming land for the specifc crop being grown in the Land Parcel by the
farmer.
Landuse Landuse refers to the utilisation of the piece of land within a land parcel or the entire land parcel.
Legal Heir
Any person who claims to be a owner of a land whose name is not recorded in the RoR but have an convincible
proof to show his/her claims for being a legal heir. However, in GRAINS / crop survey - the documents
submitted by a person for claiming the legal heir status - is only to verify and categorise the person practising
farming in the specific land parcel as cultivator with an instrument / mechanism from a owner or does farming
by the virtue of transfer of ownership due to family relationship from a person whose name is recorded in
RoR. The document submitted and name(s) recorded is not for legal verification.
Note: GRAINS is a database of farmer(s) registry on a land. It is NOT about the registry of land or the
ownership.

Overview - Crop Survey Process
Surveyor (VAO) visits every crop area (Owner / Cultivator)
 Owner / Cultivator data is received from GRAINS data
 Uses Georeferenced Digital FMB maps of villages
 One survey per season
Field Level – Crop information capture
 Geo-fenced validation for location correctness of survey numbers
 Crop Details captured after the geofenced validation
 Multiple crops within a survey number captured, separately
Users are pre-registered in the web application.

Cropping Method
 Mono Crop
 Single crop for the entire land parcel or in portion of land parcel.
 Single Landuse for the entire land parcel or a portion of land parcel
 Multiple single crops can be added
> ie in a one Hectacre land – 50 Ares can be paddy, 30 Are’s can be groundnut, 15 Are’s can be non-agricultural - barren
land, 5 Are’s can be under Agrcultural use- well and pumpset etc,
 Inter Crop
 More than one crop covered in the land parcel area. (For ex: one crop in one line and another crop in another
line). In this, total crop area should be equally divided between the crops
Total Area of all crops / landuse under mono or intercrop area should be equal to the total area in ROR
 Mixed
 More than one crop in the farming area of Land parcel, effectively. Ex: Arecanut and bettle leaves, rubber –
pepper etc
 Multilevel
 Mixed crop but grown under multi heights. The total area covered by mixed / multi level crops can’t be more
than twice the land area – as per ROR
 All area units shall be in Hectares and Are’s.
