The Organization for Economic Co-operation and Development (OECD) has raised the projection for India’s economic growth rate by 4.7 per centage points at 12.6 per cent for 2021-22. That would enable India to retain its earlier tag of the fastest growing large economy in the world.
In its interim report on economic outlook, OECD said: “Activity moved above pre-pandemic levels in China, India, and Turkey, helped by strong fiscal and quasi-fiscal measures and a recovery in manufacturing and construction.”
It, however, pegged economic growth rate to come down to 5.4 per cent in 2022-23, which would be higher by 0.6 percentage points than its earlier estimates. That year, India would share its fastest-growing large economy tag with Indonesia, according to the OECD. This meant that economic rebound in 2021-22 would largely be a statistical illusion due to low base effect.
The Indian economy was officially projected to decline by 8 per cent in the current fiscal year. However, OECD believes that contraction would be less steep at 7.4 per cent. In the report, titled “Strengthening the recovery: The need for speed”, OECD said fiscal measures announced in India and a few other countries would help growth in 2021-22 as well.
“Additional discretionary fiscal measures announced in several countries during the past three months will add to the overall support, including in the US, Japan, Germany, Canada, and India,” the report said.

The word ‘extension’ is derived from the Latin roots, ‘ex’ – meaning ‘out’ and ‘tensio’ meaning ‘stretching’. Stretching out is the meaning of extension. The word ‘extension’ came to be used originally in USA during 1914 which means “a branch of a university for students who cannot attend the university proper. In other words, the word “extension” signifies an out-ofschool system of education.

Surveying is defines as the art of determining the relative positions of various points above, on or below the surface of the earth.
The ultimate object of survey is to prepare a map or plant using the data obtained through the survey. The collection of data by linear and angular measurements and elevation difference is called the field work. The processing of data plotting and computation of area and volume are called office work.
Use of agricultural survey
Surveying is primarily divided into two types.
1. Plane surveying
2. Geodetic surveying
Agricultural surveying is the simplest form of plane surveying. With the use of survey, the boundaries of fields can be correctly located and area can be accurately computed. Land leveling and grading may be perfectly done if the differences in elevations are known. Alignments of canals for irrigation and drainage can be effectively done by proper surveying. Surveying plays a vital role in soil conservation measures like contour bunding, graded bunding, bench terracing construction of farm ponds and percolation ponds etc. In addition to this, surveying plays a key role in laying underground pipe line system, alignment of irrigation channels, drainage systems, farm roads and farm stead construction etc.
For linear and angular measurements in the plains, chain, compass and plane table surveys are used with necessary instruments. To determine the difference in elevation a dumpy level is used. The details of instruments used in each survey are given below:
1. Chain survey
2. Chain and Tape
3. Cross Staff
4. Ranging rods
5. Offset Rods
6. Arrows
2.Compass Survey
1. Prismatic Compass
2. Chain
3. Ranging Rods
4. Offset Rods
3.Plane Table Survey
1. Plane Table with Tripod Stand
2. Alidade
3. Trough Compass
4. ‘U’ frame with plumb bob
5. Spirit Level
6. Chain
7. Ranging Rods
4. Leveling
1. Dumpy Level
2. Tripod Stand
3. Telescopic Metric Staff

Aim:
To locate the boundaries of a given field and also to determine the area.
Instruments required:
Chain, Cross staff, Arrows, Ranging rods and Offset rods
Procedure:
In order to calculate the area of any irregular shaped field, it is necessary to divide
that area into number of right angled triangles and trapezoids.
Corners along the boundary of the field should be first identified and named as A,
B, C, D, E, F, G etc. in clockwise direction. Any two stations located in opposite sides
should be selected in such a way that distance between them is the longest of other
stations and almost equal numbers of corners/ stations are located on both sides.
Chaining should be started along the base line and offset distance to the corners on both
sides to be measured simultaneously after ranging, as already explained. All the details
should be entered in the field book.
Care should be taken that no offset is overlooked before the chain is moved
forward. To check the accuracy of the field work boundary line between any two corners
should be measured directly and compared. After the field work is over the survey data
may be plotted to a suitable scale on a drawing paper.
measure of dominance:
1. More number of species: In the animal kingdom more than 85 per cent of the species belongs to insect group. Total number of insects described so far is more than 9 lakhs.
2. Large number of individuals in a single species:
3. e.g., Locust swarm comprising of 109 number of individuals, occupying large area.
4. Great variety of habitats: Insects thrive well under varied conditions.
5. Long geological history: Insects were known to occupy this earth for more than 350 million years, which is a good track record. This has given the insects great variety of adoptions under different conditions.
reasons for dominance:
1. Capacity for flight: Insects posess wings, which is the lateral extension of exoskeleton. Insects are the earliest animals and the only flying invertebrates. Flight is used for the following purpose.
2. i. To seek food, mate, shelter and oviposition sites ii. To colonize in a new habitat and also to exchange habitat. iii. To escape from enemies and unfavourable conditions. iv. To migrate (i.e. for long distance travel e.g. Locusts)
3. Adaptability or Universality: Insects are the earliest groups to make their life on the earth and to occupy vast habitats of soil and water.
4. Found in wide range of climatic conditions, from -50C to 40C.
5. Psilopa petroli found in crude petroleum well. i Ephydra fly living in great salt lake. iv. Every flowering plant providing food for one or many Phytophagous insects.
6. Even the decomposing materials serving as food for many Saprophagous insects.
7. Many Carnivorous insects are parasitic on other animals and insects.
8. 3. Size: Majority of insects are small conferring the following physiological and ecological advantages.
9. Exploitation of numerous ecological niches inaccessible for other animals.
10. Less space, food, time and energy requirements for development and sustaining life. i Energy Utilization maximum. iv. Less gravitational effect.
11. Muscular action and tracheal respiration more effective.
12. Easy escape from enemies.
13. Exoskeleton: Insect body is covered with an outer cuticle called exoskeleton which is made up of a cuticular protein called Chitin. This is light in weight and gives strength, rigidity and flexibility to the insect body.

Trilobita (an extinct group)
Aim: To determine the area of the given field by radiation and intersection method using a prismatic compass. Instruments required: Prismatic Compass, Chain, Arrows, and Ranging rods Procedure: After conducting the reconnaissance survey, the surveyor should fix up the positions of all the station, around the given field as usual. The survey may be conducted under the following methods. (1) Radiation method (2) Intersection method
RADIATION METHOD
(a) Field work
In this method, the approximate centre of the field is located and the compass is exactly centered over that stations, say ‘O’ by dropping a small pebble to fall from the centre of the compass and hit the peg. Then make the compass needle horizontal by adjusting the ball and socket joint. After centering and leveling of the compass, raise the sighting vane and prism of compass. The compass box is rotated until the ranging rod at first station ‘A’ hairline of object vane and slit of the sighting vane are in the same line. Then take the reading accurately and note down the bearing of line OA. In the similar way take bearing of lines OB, OC, OD and OE by rotating the compass box in the respective directions. The readings will indicate the angles with which the line, OA, OB, OC, OD and OE makes with the north line. Then with the help of chain, measure the distances OA, OB, OC, OD and OE on ground, after proper ranging.
(b) PlottingBy knowing the observed bearings and distances to all the stations from the centre‘O’ the plan of the plot can be easily drawn by adopting a suitable scale. Join the stationpoints A, B, C, D, E which will indicate the plan of the plot. The area enclosed by theplot may be calculated by splitting the plan into number of triangles.

The Organization for Economic Co-operation and Development (OECD) has raised the projection for India’s economic growth rate by 4.7 per centage points at 12.6 per cent for 2021-22. That would enable India to retain its earlier tag of the fastest growing large economy in the world.
In its interim report on economic outlook, OECD said: “Activity moved above pre-pandemic levels in China, India, and Turkey, helped by strong fiscal and quasi-fiscal measures and a recovery in manufacturing and construction.”
It, however, pegged economic growth rate to come down to 5.4 per cent in 2022-23, which would be higher by 0.6 percentage points than its earlier estimates. That year, India would share its fastest-growing large economy tag with Indonesia, according to the OECD. This meant that economic rebound in 2021-22 would largely be a statistical illusion due to low base effect.
The Indian economy was officially projected to decline by 8 per cent in the current fiscal year. However, OECD believes that contraction would be less steep at 7.4 per cent. In the report, titled “Strengthening the recovery: The need for speed”, OECD said fiscal measures announced in India and a few other countries would help growth in 2021-22 as well.
“Additional discretionary fiscal measures announced in several countries during the past three months will add to the overall support, including in the US, Japan, Germany, Canada, and India,” the report said.

The word ‘extension’ is derived from the Latin roots, ‘ex’ – meaning ‘out’ and ‘tensio’ meaning ‘stretching’. Stretching out is the meaning of extension. The word ‘extension’ came to be used originally in USA during 1914 which means “a branch of a university for students who cannot attend the university proper. In other words, the word “extension” signifies an out-ofschool system of education.

Surveying is defines as the art of determining the relative positions of various points above, on or below the surface of the earth.
The ultimate object of survey is to prepare a map or plant using the data obtained through the survey. The collection of data by linear and angular measurements and elevation difference is called the field work. The processing of data plotting and computation of area and volume are called office work.
Use of agricultural survey
Surveying is primarily divided into two types.
1. Plane surveying
2. Geodetic surveying
Agricultural surveying is the simplest form of plane surveying. With the use of survey, the boundaries of fields can be correctly located and area can be accurately computed. Land leveling and grading may be perfectly done if the differences in elevations are known. Alignments of canals for irrigation and drainage can be effectively done by proper surveying. Surveying plays a vital role in soil conservation measures like contour bunding, graded bunding, bench terracing construction of farm ponds and percolation ponds etc. In addition to this, surveying plays a key role in laying underground pipe line system, alignment of irrigation channels, drainage systems, farm roads and farm stead construction etc.
For linear and angular measurements in the plains, chain, compass and plane table surveys are used with necessary instruments. To determine the difference in elevation a dumpy level is used. The details of instruments used in each survey are given below:
1. Chain survey
2. Chain and Tape
3. Cross Staff
4. Ranging rods
5. Offset Rods
6. Arrows
2.Compass Survey
1. Prismatic Compass
2. Chain
3. Ranging Rods
4. Offset Rods
3.Plane Table Survey
1. Plane Table with Tripod Stand
2. Alidade
3. Trough Compass
4. ‘U’ frame with plumb bob
5. Spirit Level
6. Chain
7. Ranging Rods
4. Leveling
1. Dumpy Level
2. Tripod Stand
3. Telescopic Metric Staff

Aim:
To locate the boundaries of a given field and also to determine the area.
Instruments required:
Chain, Cross staff, Arrows, Ranging rods and Offset rods
Procedure:
In order to calculate the area of any irregular shaped field, it is necessary to divide
that area into number of right angled triangles and trapezoids.
Corners along the boundary of the field should be first identified and named as A,
B, C, D, E, F, G etc. in clockwise direction. Any two stations located in opposite sides
should be selected in such a way that distance between them is the longest of other
stations and almost equal numbers of corners/ stations are located on both sides.
Chaining should be started along the base line and offset distance to the corners on both
sides to be measured simultaneously after ranging, as already explained. All the details
should be entered in the field book.
Care should be taken that no offset is overlooked before the chain is moved
forward. To check the accuracy of the field work boundary line between any two corners
should be measured directly and compared. After the field work is over the survey data
may be plotted to a suitable scale on a drawing paper.
measure of dominance:
1. More number of species: In the animal kingdom more than 85 per cent of the species belongs to insect group. Total number of insects described so far is more than 9 lakhs.
2. Large number of individuals in a single species:
3. e.g., Locust swarm comprising of 109 number of individuals, occupying large area.
4. Great variety of habitats: Insects thrive well under varied conditions.
5. Long geological history: Insects were known to occupy this earth for more than 350 million years, which is a good track record. This has given the insects great variety of adoptions under different conditions.
reasons for dominance:
1. Capacity for flight: Insects posess wings, which is the lateral extension of exoskeleton. Insects are the earliest animals and the only flying invertebrates. Flight is used for the following purpose.
2. i. To seek food, mate, shelter and oviposition sites ii. To colonize in a new habitat and also to exchange habitat. iii. To escape from enemies and unfavourable conditions. iv. To migrate (i.e. for long distance travel e.g. Locusts)
3. Adaptability or Universality: Insects are the earliest groups to make their life on the earth and to occupy vast habitats of soil and water.
4. Found in wide range of climatic conditions, from -50C to 40C.
5. Psilopa petroli found in crude petroleum well. i Ephydra fly living in great salt lake. iv. Every flowering plant providing food for one or many Phytophagous insects.
6. Even the decomposing materials serving as food for many Saprophagous insects.
7. Many Carnivorous insects are parasitic on other animals and insects.
8. 3. Size: Majority of insects are small conferring the following physiological and ecological advantages.
9. Exploitation of numerous ecological niches inaccessible for other animals.
10. Less space, food, time and energy requirements for development and sustaining life. i Energy Utilization maximum. iv. Less gravitational effect.
11. Muscular action and tracheal respiration more effective.
12. Easy escape from enemies.
13. Exoskeleton: Insect body is covered with an outer cuticle called exoskeleton which is made up of a cuticular protein called Chitin. This is light in weight and gives strength, rigidity and flexibility to the insect body.

Aim: To determine the area of the given field by radiation and intersection method using a prismatic compass. Instruments required: Prismatic Compass, Chain, Arrows, and Ranging rods Procedure: After conducting the reconnaissance survey, the surveyor should fix up the positions of all the station, around the given field as usual. The survey may be conducted under the following methods. (1) Radiation method (2) Intersection method
RADIATION METHOD
(a) Field work
In this method, the approximate centre of the field is located and the compass is exactly centered over that stations, say ‘O’ by dropping a small pebble to fall from the centre of the compass and hit the peg. Then make the compass needle horizontal by adjusting the ball and socket joint. After centering and leveling of the compass, raise the sighting vane and prism of compass. The compass box is rotated until the ranging rod at first station ‘A’ hairline of object vane and slit of the sighting vane are in the same line. Then take the reading accurately and note down the bearing of line OA. In the similar way take bearing of lines OB, OC, OD and OE by rotating the compass box in the respective directions. The readings will indicate the angles with which the line, OA, OB, OC, OD and OE makes with the north line. Then with the help of chain, measure the distances OA, OB, OC, OD and OE on ground, after proper ranging.
(b) PlottingBy knowing the observed bearings and distances to all the stations from the centre‘O’ the plan of the plot can be easily drawn by adopting a suitable scale. Join the stationpoints A, B, C, D, E which will indicate the plan of the plot. The area enclosed by theplot may be calculated by splitting the plan into number of triangles.

Surveying is defines as the art of determining the relative positions of various points above, on or below the surface of the earth.
The ultimate object of survey is to prepare a map or plant using the data obtained through the survey. The collection of data by linear and angular measurements and elevation difference is called the field work. The processing of data plotting and computation of area and volume are called office work.
Use of agricultural survey
Surveying is primarily divided into two types.
1. Plane surveying
2. Geodetic surveying
Agricultural surveying is the simplest form of plane surveying. With the use of survey, the boundaries of fields can be correctly located and area can be accurately computed. Land leveling and grading may be perfectly done if the differences in elevations are known. Alignments of canals for irrigation and drainage can be effectively done by proper surveying. Surveying plays a vital role in soil conservation measures like contour bunding, graded bunding, bench terracing construction of farm ponds and percolation ponds etc. In addition to this, surveying plays a key role in laying underground pipe line system, alignment of irrigation channels, drainage systems, farm roads and farm stead construction etc.
For linear and angular measurements in the plains, chain, compass and plane table surveys are used with necessary instruments. To determine the difference in elevation a dumpy level is used. The details of instruments used in each survey are given below:
1. Chain survey
2. Chain and Tape
3. Cross Staff
4. Ranging rods
5. Offset Rods
6. Arrows
2.Compass Survey
1. Prismatic Compass
2. Chain
3. Ranging Rods
4. Offset Rods
3.Plane Table Survey
1. Plane Table with Tripod Stand
2. Alidade
3. Trough Compass

Aim:
To locate the boundaries of a given field and also to determine the area.
Instruments required:
Chain, Cross staff, Arrows, Ranging rods and Offset rods
Procedure:
In order to calculate the area of any irregular shaped field, it is necessary to divide
that area into number of right angled triangles and trapezoids.
Corners along the boundary of the field should be first identified and named as A,
B, C, D, E, F, G etc. in clockwise direction. Any two stations located in opposite sides
should be selected in such a way that distance between them is the longest of other
stations and almost equal numbers of corners/ stations are located on both sides.
Chaining should be started along the base line and offset distance to the corners on both
sides to be measured simultaneously after ranging, as already explained. All the details
should be entered in the field book.
Care should be taken that no offset is overlooked before the chain is moved
forward. To check the accuracy of the field work boundary line between any two corners
should be measured directly and compared. After the field work is over the survey data
may be plotted to a suitable scale on a drawing paper.
measure of dominance:
1. More number of species: In the animal kingdom more than 85 per cent of the species belongs to insect group. Total number of insects described so far is more than 9 lakhs.
2. Large number of individuals in a single species:
3. e.g., Locust swarm comprising of 109 number of individuals, occupying large area.
4. Great variety of habitats: Insects thrive well under varied conditions.
5. Long geological history: Insects were known to occupy this earth for more than 350 million years, which is a good track record. This has given the insects great variety of adoptions under different conditions.
reasons for dominance:
1. Capacity for flight: Insects posess wings, which is the lateral extension of exoskeleton. Insects are the earliest animals and the only flying invertebrates. Flight is used for the following purpose.
2. i. To seek food, mate, shelter and oviposition sites ii. To colonize in a new habitat and also to exchange habitat. iii. To escape from enemies and unfavourable conditions. iv. To migrate (i.e. for long distance travel e.g. Locusts)
3. Adaptability or Universality: Insects are the earliest groups to make their life on the earth and to occupy vast habitats of soil and water.
4. Found in wide range of climatic conditions, from -50C to 40C.
5. Psilopa petroli found in crude petroleum well. i Ephydra fly living in great salt lake. iv. Every flowering plant providing food for one or many Phytophagous insects.
6. Even the decomposing materials serving as food for many Saprophagous insects.
7. Many Carnivorous insects are parasitic on other animals and insects.
8. 3. Size: Majority of insects are small conferring the following physiological and ecological advantages.
9. Exploitation of numerous ecological niches inaccessible for other animals.
10. Less space, food, time and energy requirements for development and sustaining life. i Energy Utilization maximum. iv. Less gravitational effect.
11. Muscular action and tracheal respiration more effective.
12. Easy escape from enemies.
13. Exoskeleton: Insect body is covered with an outer cuticle called exoskeleton which is made up of a cuticular protein called Chitin. This is light in weight and gives strength, rigidity and flexibility to the insect body.

Aim: To determine the area of the given field by radiation and intersection method using a prismatic compass. Instruments required: Prismatic Compass, Chain, Arrows, and Ranging rods Procedure: After conducting the reconnaissance survey, the surveyor should fix up the positions of all the station, around the given field as usual. The survey may be conducted under the following methods. (1) Radiation method (2) Intersection method
RADIATION METHOD
(a) Field work
In this method, the approximate centre of the field is located and the compass is exactly centered over that stations, say ‘O’ by dropping a small pebble to fall from the centre of the compass and hit the peg. Then make the compass needle horizontal by adjusting the ball and socket joint. After centering and leveling of the compass, raise the sighting vane and prism of compass. The compass box is rotated until the ranging rod at first station ‘A’ hairline of object vane and slit of the sighting vane are in the same line. Then take the reading accurately and note down the bearing of line OA. In the similar way take bearing of lines OB, OC, OD and OE by rotating the compass box in the respective directions. The readings will indicate the angles with which the line, OA, OB, OC, OD and OE makes with the north line. Then with the help of chain, measure the distances OA, OB, OC, OD and OE on ground, after proper ranging.
(b) PlottingBy knowing the observed bearings and distances to all the stations from the centre‘O’ the plan of the plot can be easily drawn by adopting a suitable scale. Join the stationpoints A, B, C, D, E which will indicate the plan of the plot. The area enclosed by theplot may be calculated by splitting the plan into number of triangles.

The Organization for Economic Co-operation and Development (OECD) has raised the projection for India’s economic growth rate by 4.7 per centage points at 12.6 per cent for 2021-22. That would enable India to retain its earlier tag of the fastest growing large economy in the world.
In its interim report on economic outlook, OECD said: “Activity moved above pre-pandemic levels in China, India, and Turkey, helped by strong fiscal and quasi-fiscal measures and a recovery in manufacturing and construction.”
It, however, pegged economic growth rate to come down to 5.4 per cent in 2022-23, which would be higher by 0.6 percentage points than its earlier estimates. That year, India would share its fastest-growing large economy tag with Indonesia, according to the OECD. This meant that economic rebound in 2021-22 would largely be a statistical illusion due to low base effect.
The Indian economy was officially projected to decline by 8 per cent in the current fiscal year. However, OECD believes that contraction would be less steep at 7.4 per cent. In the report, titled “Strengthening the recovery: The need for speed”, OECD said fiscal measures announced in India and a few other countries would help growth in 2021-22 as well.
“Additional discretionary fiscal measures announced in several countries during the past three months will add to the overall support, including in the US, Japan, Germany, Canada, and India,” the report said.

Aim:
To locate the boundaries of a given field and also to determine the area.
Instruments required:
Chain, Cross staff, Arrows, Ranging rods and Offset rods
Procedure:
In order to calculate the area of any irregular shaped field, it is necessary to divide
that area into number of right angled triangles and trapezoids.
Corners along the boundary of the field should be first identified and named as A,
B, C, D, E, F, G etc. in clockwise direction. Any two stations located in opposite sides
should be selected in such a way that distance between them is the longest of other
stations and almost equal numbers of corners/ stations are located on both sides.
Chaining should be started along the base line and offset distance to the corners on both
sides to be measured simultaneously after ranging, as already explained. All the details
should be entered in the field book.
Care should be taken that no offset is overlooked before the chain is moved
forward. To check the accuracy of the field work boundary line between any two corners
should be measured directly and compared. After the field work is over the survey data
may be plotted to a suitable scale on a drawing paper.

Aim: To determine the area of the given field by radiation and intersection method using a prismatic compass. Instruments required: Prismatic Compass, Chain, Arrows, and Ranging rods Procedure: After conducting the reconnaissance survey, the surveyor should fix up the positions of all the station, around the given field as usual. The survey may be conducted under the following methods. (1) Radiation method (2) Intersection method
RADIATION METHOD
(a) Field work
In this method, the approximate centre of the field is located and the compass is exactly centered over that stations, say ‘O’ by dropping a small pebble to fall from the centre of the compass and hit the peg. Then make the compass needle horizontal by adjusting the ball and socket joint. After centering and leveling of the compass, raise the sighting vane and prism of compass. The compass box is rotated until the ranging rod at first station ‘A’ hairline of object vane and slit of the sighting vane are in the same line. Then take the reading accurately and note down the bearing of line OA. In the similar way take bearing of lines OB, OC, OD and OE by rotating the compass box in the respective directions. The readings will indicate the angles with which the line, OA, OB, OC, OD and OE makes with the north line. Then with the help of chain, measure the distances OA, OB, OC, OD and OE on ground, after proper ranging.
(b) PlottingBy knowing the observed bearings and distances to all the stations from the centre‘O’ the plan of the plot can be easily drawn by adopting a suitable scale. Join the stationpoints A, B, C, D, E which will indicate the plan of the plot. The area enclosed by theplot may be calculated by splitting the plan into number of triangles.

The Organization for Economic Co-operation and Development (OECD) has raised the projection for India’s economic growth rate by 4.7 per centage points at 12.6 per cent for 2021-22. That would enable India to retain its earlier tag of the fastest growing large economy in the world.
In its interim report on economic outlook, OECD said: “Activity moved above pre-pandemic levels in China, India, and Turkey, helped by strong fiscal and quasi-fiscal measures and a recovery in manufacturing and construction.”
It, however, pegged economic growth rate to come down to 5.4 per cent in 2022-23, which would be higher by 0.6 percentage points than its earlier estimates. That year, India would share its fastest-growing large economy tag with Indonesia, according to the OECD. This meant that economic rebound in 2021-22 would largely be a statistical illusion due to low base effect.
The Indian economy was officially projected to decline by 8 per cent in the current fiscal year. However, OECD believes that contraction would be less steep at 7.4 per cent. In the report, titled “Strengthening the recovery: The need for speed”, OECD said fiscal measures announced in India and a few other countries would help growth in 2021-22 as well.
“Additional discretionary fiscal measures announced in several countries during the past three months will add to the overall support, including in the US, Japan, Germany, Canada, and India,” the report said.

The word ‘extension’ is derived from the Latin roots, ‘ex’ – meaning ‘out’ and ‘tensio’ meaning ‘stretching’. Stretching out is the meaning of extension. The word ‘extension’ came to be used originally in USA during 1914 which means “a branch of a university for students who cannot attend the university proper. In other words, the word “extension” signifies an out-ofschool system of education.

Surveying is defines as the art of determining the relative positions of various points above, on or below the surface of the earth.
The ultimate object of survey is to prepare a map or plant using the data obtained through the survey. The collection of data by linear and angular measurements and elevation difference is called the field work. The processing of data plotting and computation of area and volume are called office work.
Use of agricultural survey
Surveying is primarily divided into two types.
1. Plane surveying
2. Geodetic surveying
Agricultural surveying is the simplest form of plane surveying. With the use of survey, the boundaries of fields can be correctly located and area can be accurately computed. Land leveling and grading may be perfectly done if the differences in elevations are known. Alignments of canals for irrigation and drainage can be effectively done by proper surveying. Surveying plays a vital role in soil conservation measures like contour bunding, graded bunding, bench terracing construction of farm ponds and percolation ponds etc. In addition to this, surveying plays a key role in laying underground pipe line system, alignment of irrigation channels, drainage systems, farm roads and farm stead construction etc.
For linear and angular measurements in the plains, chain, compass and plane table surveys are used with necessary instruments. To determine the difference in elevation a dumpy level is used. The details of instruments used in each survey are given below:
1. Chain survey
2. Chain and Tape
3. Cross Staff
4. Ranging rods
5. Offset Rods
6. Arrows
2.Compass Survey
1. Prismatic Compass
2. Chain
3. Ranging Rods
4. Offset Rods
3.Plane Table Survey
1. Plane Table with Tripod Stand
2. Alidade
3. Trough Compass
4. ‘U’ frame with plumb bob
5. Spirit Level
6. Chain
7. Ranging Rods
4. Leveling
1. Dumpy Level
2. Tripod Stand
3. Telescopic Metric Staff

Aim: To determine the area of the given field by radiation and intersection method using a prismatic compass. Instruments required: Prismatic Compass, Chain, Arrows, and Ranging rods Procedure: After conducting the reconnaissance survey, the surveyor should fix up the positions of all the station, around the given field as usual. The survey may be conducted under the following methods. (1) Radiation method (2) Intersection method
RADIATION METHOD
(a) Field work
In this method, the approximate centre of the field is located and the compass is exactly centered over that stations, say ‘O’ by dropping a small pebble to fall from the centre of the compass and hit the peg. Then make the compass needle horizontal by adjusting the ball and socket joint. After centering and leveling of the compass, raise the sighting vane and prism of compass. The compass box is rotated until the ranging rod at first station ‘A’ hairline of object vane and slit of the sighting vane are in the same line. Then take the reading accurately and note down the bearing of line OA. In the similar way take bearing of lines OB, OC, OD and OE by rotating the compass box in the respective directions. The readings will indicate the angles with which the line, OA, OB, OC, OD and OE makes with the north line. Then with the help of chain, measure the distances OA, OB, OC, OD and OE on ground, after proper ranging.
(b) PlottingBy knowing the observed bearings and distances to all the stations from the centre‘O’ the plan of the plot can be easily drawn by adopting a suitable scale. Join the stationpoints A, B, C, D, E which will indicate the plan of the plot. The area enclosed by theplot may be calculated by splitting the plan into number of triangles.
