2. What Extension Does?
- To bring desirable changes in behavior
The changeable behavioral components are
- Change in knowledge
- Change in skill
- Change in attitude
- Change in understanding
- Change in goal
- Change in actions
- Change in confidence

3. Principles of Agricultural
Extension
“Principles is said to be statement of
policy to guide decision and action in a
consistent manner”
Further “it is a universal truth and
found to be true under varying
conditions & circumstances”

4. The widely applied and tested Principles
of Agricultural Extension are-
- It becomes effective when it values the
knowledge and resource of local people
- It becomes effective if there is a firm
relationship between research and
extension
- It becomes effective when it follows the
whole family approach.

5. Cont’d
- It becomes effective when every extn
personnel has a plan of work
- It becomes effective when local leaders
are trained and utilized
- It becomes effective when available local
resources are fully utilized
- It becomes effective when each new or
changed practice is both technically
sound and financially profitable

6. Cont’d
- It becomes effective when extn contact
with farmers is fitted into times when
they are not otherwise busy
- It becomes effective when the results of
each practice are demonstrated just
before the time of use
- It becomes effective when client system
actively participate in extn activities
- It becomes effective when it fulfills the
need and interest of people

7. Cont’d
- It becomes effective when it works with
old institutions rather than creating new
institutions
- It becomes effective when extn
programme is monitored and evaluated
at regular interval
- It becomes effective when a wide variety
of teaching methods are used
- It becomes effective when local culture
is duly recognized and respected

8. Technology
- Technology is the subject of
agricultural extension that is taught to
the farmers.
- In fact, it becomes the central theme of
extension teaching.
- Technology should be problem-solving
oriented.
- More the adoption of technology more
the development of agriculture.

9. What is Technology/Innovation?
An innovation is an idea, practice, or object
that is perceived as new by an individual or
other unit of adoption (Rogers, 1995).
An innovation may not be new to all people at
the same time. When an individual already
aware of any or object that is not an
innovation for him, but an individual who
was quite unaware of the same idea or object
that may be innovation for him.

10. 1. Newness
2. Technical appropriateness
3. Experimentally proved
4. Environmentally-friendliness/
Environment friendly
5. Sustainability
Characteristics/Attributes of
an innovation /a technology

11. 6. Relative advantage/Profitability/Economic
viability is the degree to which an innovation
is perceived as being better than the idea it
superceedes in terms of economic profitability,
social prestige, physical convenience, and
psychological satisfaction. It is usually
expressed in terms of economic gain.
7. Compatibility with i) existing norms, values
and culture; ii) existing level of farm
management; iii) the stage of farm
development; iv) the resource availability
Cont’d

12. 8. Complexity is the degree to which an innovation
is perceived as relatively difficult to understand
and use. The more complex the innovation, the
slower is its rate of adoption.
9. Trialability is the degree to which an innovation
may be experimented on a limited basis.
10. Observability is the degree to which the results
of an innovation are visible to others. The easier
the results are to observe, describe, and
communicate to others, the faster the rate of
adoption.
Cont’d

13. Diffusion is the process by which an innovation
is communicated through certain channels over
time among the members of social system
(Rogers, 1995).
The process of diffusion may be characterized
as the (1) acceptance, (2) over time, (3) of some
specific item or practice, (4) by individual,
groups or other adopting units, linked, (5) to
specific channels of communication, (6) to a
social structure, and (7) to a given system of
values, or culture (Katz et al., 1963).

15. The innovation-decision process is
the process through which an
individual (or other decision-making
unit) passes from first knowledge of
an innovation, to forming an attitude
toward the innovation, to decision to
adopt or reject, to implementation of
the new idea, and to confirmation of
this decision (Rogers, 1993, 1995).

19. 1. Awareness stage (Knowledge)- the individual
learns the existence of the new idea and gains
some understanding of how it functions.

develops interest in the innovation and forms
a favourable or unfavourable attitude toward
the innovation.
