Women account for 43% of the agricultural labor force in developing countries (FAO, 2011) and produce 50% of the global food production (FAO, 2011). Regional statistics reveal that in Latin America about, 20 percent, in Asia, about 30 to 60 percent, and in Sub-Saharan Africa, 50 to 75 percent of the agricultural labour force is supplied by women (FAO, 2013). Moreover, they invest 10 times more than their male counterpart in the family well being especially education and nutrition of children (Maertens and Verhofstadt, 2013). Despite being the primary contributors for the world food production, their roles are highly underestimated. Considerable gender bias exists in the agricultural sector, both in terms of quantities of assets, agricultural inputs and resources that women
control (Deere et al., 2013). Failure to recognize the roles, differences and inequities [between men and women] poses a serious threat to the effectiveness of the agricultural development agenda

1. Introduction
“Educational Technology is the application of scientific knowledge about learning and the conditions of learning to improve the effectiveness of teaching and training. In the absence of scientifically established principles, educational technology implements techniques of empirical testing to improve learning situation”.
Educational technology includes numerous types of media that deliver text, audio, images, animation, streaming video that includes technology applications and processes such as computer-based learning as well as local intranet/ extranet and web-based learning. Information and communication systems whether freestanding or based on either local networks or the internet in

Introduction
India with exceeding population of 1027.01 million with 741 million living in rural areas is on the path of development. The lack of access to and control over resources is said to be cause of poverty (Satapathy and  Mishra, 2011).
Women form half of our society. They have significant role in overall development. Rural development concept in our country attaches more importance to women empowerment. To combat poverty ‘self help promotion’ is of recent paradigm that has attracted attention to sections of the society.

Group Discussion
Group discussion is the method by which two or more persons meet, express or suggest their ideas for getting the solution to the felt problems by them.
Objectives of group Discussion
• To develop the democratic leadership among the members.
• To conduct the systematic group discussion to solve the problems.
• To give opportunity to each member to share experiences.
• To promote the habit of talking, thinking, group planning and group action.
• To identify the group and focus the public interest and mobilize them for group action.

‘Extension’ acts as a potential link between ‘research’ and ‘teaching’ which also facilitates transfer of technology. In this context new concepts, like Rapid Rural Appraisal (RRA) and Participatory Rural Appraisal (PRA) are becoming more meaningful now-a-days.

Rapid Rural Appraisal (RRA)
i) RRA can be defined as a systematic but semi-structured study, carried out in the field by a multi-disciplinary team over a short period ranging from three days to three weeks, based on information collected in advance from published and/or unpublished sources, direct observations and interviews as to generate working hypotheses for subsequent action
ii) RRA study aims at generating information on rural life and conditions that is relevant, timely, accurate and usable in

The following is the plan of action to hold Animal Health Camps
1. Attempt will be made to hold at Gram Panchayat level.
2. Before 2-3 days monadi of camps must be do.
3. The camp will be held for 1 day. It will start by 7 AM and close at 2 PM.
4. The venue should be selected so that it is in the central location to get cases from 3-4 villages in order to provide facilities of clinical examination, pathological tests, etc.
5. The venue should be centrally located and easily accessible to the general public.

Awareness campaign should help educate your community on a specific subject by sharing basic information and providing examples. This will help community members have healthy conversations and increase awareness. This will begin the prevention process. Any awareness campaign should include following step;
1. Choose Your Topic Or Goals
2. Find Your Resources: Awareness campaigns take a lot of resources. You might have a set budget to implement your campaign. Money is not the only resource you will be using. Resources such as time, marketing and promotional material etc also needed for successful completion of campaign.
3. Segment Your Audience
4. Create a Schedule of Events, Programs, and Initiatives

A. Circular letter
• Circular letter is a quick and cheap method of communication.
• It is a letter reproduced and sent to many people by the extension worker, to publicize an extension activity (like meeting, exhibits etc.) or to give information on farm and home problems.
• Circular letter could be used as a mail before organizing any campaign or extension work.
• It is sent from extension wing weekly or fortnightly to maintain regular contact with the farmers depending upon

Principle of construction of flash cards
• Flash cards are non-projected visual aid in which series of illustrated cards are flashed as presented in a proper sequence to explain complete story.
• The story must be familiar, with specific heading and suggestions at the last.
• Simple words and local expressions should be used in flash cards.
• Total number of flash cards must be 10 -12 which are easy to remember to farmers
• Card: Select white or light coloured thick paper.
• Flash card should be large enough for everyone to see at least 22 x 28 inches and simple line drawing or photographs or cartoons having plenty of colours.
• Content: Each set should have a title card. The story should be divided into a number of scenes,

Principle of construction of poster making
A poster is to be bold in design, simple to understand and attractive in colour. Poster is displayed in a public place with the purpose of creating awareness amongst the people. A poster is generally seen from a distance and the person glancing at to get first idea about it. Construction of poster making should be based on following components.
1. Pictures 2. Words 3. Space 4. Colors 5. Layout

a) Picture or illustration
1. Picture should be drawn in such a way that produce message clearly.

TV Talk
The talk delivered through TV i.e. through an electronic audio-visual medium which provides pictures with synchronized sound. The medium is cosmopolite in nature and can be used to develop instant mass awareness.

Important points while writing a programme for broadcasting
• Writing should be catchy, readable, conversational sound, understood and absorbed by the audience.
• Writing should be in simple, known language avoiding too much technicalities
• Interest of the listener should be sustained continuously
• Application of figures should be done judiciously
 

Radio script should be prepared in such a way that listener should feel that somebody is talking with him in a friendly manner and with informal style. For this purpose:
1. Collect the material from your experience.
2. Keep the purpose of the script and audience in mind.
3. Decide the method of presentation of information.
4. Considering the time available for the talk, the script should be prepared.
5. Generally we talk two words per seconds and 8 to 10 lines are required per minute having 5-6 words per sentences.
6. Time for talk is always limited hence select one idea at a time never include maximum technical information in the script.
7. Arrange the information in the sequences.
8. Include supporting and illustrated facts.
 

Overhead Projector
Principles of Over Head Projector (OHP)
A projector, which projects the image over the head of an instructor on the screen, is called OHP. It worked on the principle of indirect projection. With the use of lens of short focal length and two mirrors the picture is reflected on the screen. The drawing, diagram, letter (may be in colour or in black and white) etc. are made on transparent sheet and are put on the glass platform of the OHP, through which strong light is passed. The rays of light are converged by a lens and reflected by a mirror held at an angle of 45°.

“Audio-Visual aids are those instructional devices that may be used by a communicator in order to facilitate better understanding on the parts of learner by involving their many senses, particularly those relating to seeing and hearing”.
As a potential link between research institutions and livestock owners the extension agent must have good skills in effectively communicating with various stakeholders which include policy makers, researchers, input suppliers, market agents, credit institutions etc.

Identification of key communicators
For effective introduction of innovations and transfer of technology among farmers, effective communication is the prime need. An extension worker passes his information more effectively if he communicates with farmers/livestock owners through local leaders and key communicators.
Leader:  Is a person who effectively influences a group to cooperate in setting and achieving the goal.
Leadership: Leadership is a process by which an individual influence, guide and direct the thought, feelings and impressions in desired way.
Key communicators: Key communicator is a person who has maximum information about his society and vicinity area on different aspects.

Demonstrations
Demonstration means showing by doing. The basic principle of Demonstration is learning by seeing and doing. The concept of demonstration was given by Dr. Seeman A. Knapp. Farmers like to see how a new idea works, both purposes can be achieved by means of a farm demonstration. A good, practical demonstration is an invaluable method in extension work. The demonstration is a particularly powerful method to use with farmers who do not read easily. There are two principal types of demonstration used by extension agents - method demonstration and result demonstration.

The word data means facts or information, specifically collected by the researcher through observation or measurement from which meaningful conclusions are drawn. Data may be of qualitative or quantitative types:
Qualitative data are descriptive/qualitative in nature and can be statistically analyzed only after processing and after having them classified into some appropriate categories.
Quantitative data are expressed in the form of numerals and are amenable to statistical analysis readily.
Primary data are those which are collected afresh and for the first time, specifically for the designated study.

1.1. Origin and distribution
• South East Asia, with the greatest number of species found in Borneo, Java, Sumatra, and Malay Peninsula.
1.2. Varieties
• Neelum, Bangalora, Alphonso, Rumani, Banganapalli, Kalepad, Peter, PKM 1, PKM 2, Senthura, Jahangir, Mulgoa, Himayuddin, Paiyur 1, Mallika, Amrapali, Salem Bangalora, Arka Anmol, Arka Aruna, Arka Neelkiran, Arka Puneeth, Sindhu, Ratna and Arka Suprabath

1.1. Establishment of orchard
• A long term investment and deserves a very critical planning.
1.1.1. Location and site
• Well established fruit growing region, because one could get benefit of experience of other growers.
• Market should be close to the area with assured demand.
• Climate should be suitable to grow the chosen fruit crops; free from cyclones, frost, hailstorms and strong hot winds.
• Adequate and good quality water supply should be available round the year.

1. Propagation
• Multiplication of plants is termed as propagation.
• Aim to achieve increase in number and preserve essential characteristics of mother plant.
• Most of the horticultural crops are propagated through vegetative means.
• Two types of propagation
• Sexual propagation - through seeds which is formed by sexual reproduction
• Asexual propagation - through vegetative parts or organs of a plant.

I. Importance of Growth and Development
• Growth is an irreversible increase in size and evaluated by mass length and height, surface area or volume.
• Growth is produced by cell division in meristem.
• Root and shoot of vascular cambium are meristematic.
• Apical meristem of root and shoot is developed during embryo development.
• Plant growth is determinate (leaves, flowers, fruits) or indeterminate (root, stem).
• Monocarpic species flowers only once and die.
• Polycarpic species after flowering return to vegetative and flower at once before drying.
• Monocarpic annuals – monocarpic species lives for only one year/one season. Eg. Marigold, cosmos etc.

I. Scope and Importance of Horticulture
• The total Geographical area of India is 328.73 ha which stands seventh position in the world.
• India’s population is about 138.5 crores as on November 5, 2020 (UN data) which stands second in the world after China.
• Population depends on agriculture is around 55-70%.
• The term Horticulture derived from two Latin words, Hortus - Garden, Cultura - Cultivation.
• Protected enclosures are used to grow vegetables, flowers and ornamental plants etc

Bael (Angle marmelos) is an important arid fruits belongs to family Rutaceae and consists 2-3 species of which only one is in cultivation. It is important indigenous fruits of India, drought hardy tree, flowering and fruiting coincides with the onset of monsoon and fruits mature before commencement of summer. The tree shed off entire leaves during hot summer and fruits are exposed to direct sunlight, which favors ripening of fruits.

Papaya (Carica papaya) is a important delicious fruits of herbaceous in nature,. It is most precocious fruit crops cultivated as pure as well as intercropped with mango, guava, peach, and coconut. Papaya starts bearing in 8-10 months after planting.

Ber (Ziziphus mauritiana L) ancient fruit of India grown in arid regions, ‘king of arid zone fruits’, thrive well in marginal areas. During severe hot, it shed off its leaves completely and thus conserves moisture by getting rid of transpiration mechanism. Flowering and fruiting mainly take place on secondary and tertiary branches.

There are number of eating type kiwi fruits in world but Actinidia deliciosa Chev, is most common. It was the recently introduced fruit in India. It was origin of China the oval fruits have flavor of gooseberry. It is egg sized, fuzzy, brown skinned green fleshed kiwifruit. Fruit is a berry, where as Actinidia chinenses a yellow fleshed fruits.

Japanese plum (Prunus salicina) is usually eaten as fresh while as European plum (Prunus domestica) required to process before consumption. Plum ranks next to peach as for as its economic importance is concerned. It is a delicious juicy fruit, prized both for its exquisite fresh fruit flavor and in processing industry. Due to its typical chilling requirement it is grown in cooler region. Two types of plum i.e. Japanese plum and its hybrids and European plum are grown in India.

It is an interesting and popular fruits of temperate climate. The branches are usually erect and leaves are large and thin, the flowers borne on one-yearold spur and shoots. The spur elongates in almost a straight line for several successive years because the terminal bud is leaf bud. Sweet cherry fruits are mostly consumed fresh and also used for processing purpose, syrup and some type of alcoholic drinks etc.

Peach (Prunus persica L. Batsch) is a small to medium sized open topped branches, medium stocky, spreading as well as upright growth habit. The Peach is the native of (china, currently around 3000 peach cultivars are available in the world over (Faust and Timon, 1995).

The common pear (Pyrus communis) is known as French Pear, Asian pear also called Chinese pears, Japanese pears, Oriental pears, sand pear, salad pears and apple and pear are group of pome fruits derived from Pyrus ussuriensis and Pyrus serotina. Pyrus communis is susceptible to fireblight disease, however, Pyrus pyrifolia is resistant to this disease. Pear is only temperate fruit grown on the hills to southern parts of India. Jammu and Kashmir is leading in quality pear production.

Apple (Malus domestica Borkh) is a typical temperate fruit; more than 80% world supply is being made from Europe (Tukey, 1982). It occupies more than 85% area and 60 % production of total temperate fruits. As per 2017-18 statistics it was cultivated over an area of 30,1000 ha with 23,27,000 metric tons production (Anonymous, 2018). Austria is leading in apple productivity; however, China is a largest producer in world.

India stands 3rd position in citrus production in world after China and Brazil. It is the most important fruit crops grown in India, however, our productivity is quite low 8.9 t/ha (Srivastava and Singh, 2006).

The guava (Psidium guajava L.) also known as ‘the apple of tropics’ belongs to family Myrtaceae (Hayes, 1974) originated from Tropical South America stretching from Mexico to Peru and introduced in India by Portuguese during 17th century (Bose and Mitra, 2001). Guava is an evergreen fruit in nature, well adopted to a wide range of soil and agro-climates and acclaimed as ‘super fruit, due to high nutraceutical properties and in reach of poor people it has great demand.

Banana and plantain (Musa spp.) are one of the most important commercial food crops especially in tropical regions. Banana by virtue of its multiple uses is popularly known as ‘Kalpataru’. Apart from fresh consumption as desert fruit, some types are also used for culinary purposes. It has therapeutic value; ripe banana is easily digestible and has vitamins and minerals.

Grape is one of the important fruit, crops being grown in area of 79.6 thousand hectare with annual production 1878.3 thousand MT. India is a major exporting country of grapes, it exported fresh grapes 24633.79 MT (2018-19) (Anonymous, 2018).

Mango (Mangifera indica) is one of the least professionally grown fruit crop globally. It is popularly known as ‘King of Fruits’ belongs to family Anacardiaceae. It is being cultivated for at least 4000 years (Crane, 2008). As per estimate total world mango production is 40 million tones.

Canopy manipulation in fruit crops has a seasonal and a life-time development pattern and have lifelong advantage and disadvantage. The unmanaged canopy of fruit trees poses many difficulties i.e. difficulty in spray, pruning and hand harvesting, poor light penetration and interception throughout the canopy. Low early light interception, leaf area index and fraction of land covered by canopy, leading to delayed and poor cropping.

Tree canopy management affects fruit yield and quality by affecting light interception. The canopy geometry should be managed in such a way that it intercepts maximum light. For high density planting system a shallow (thin) canopy 1.5-2.0 m in depth is needed to achieve the maximum efficiency for trapping sun energy through foliage and channelizing metabolites for quality fruit production with good return.

Over the last decade, area under horticultural crops grew by 2.60% per annum and production 4.8% per annum. During 2017-18 total 311.71 million tonnes horticultural crops were harvested from 25.43 million hectare area. India is 2nd largest producer of fruits in the world after China, with average productivity at 14.97 t/ha. Fruits alone were cultivated almost in 6.5 million hectare area and production of 97.38 million metric tons, (Anonymous, 2018).
