3 Rationale: Expert System of Extension

4 Introduction of Extension 1866Great Famine of Bengal & Orissa Rabindranath Tagore-Self help and Mutual help Mahatma Gandhi-Improvement in their inner man 1880Famine Commission 1901Famine Commission 1928Royal Commission To Meet the Food Need (Quantity) Quality, Precision and Economic gain Rationale 1

5 Personal & Group Contact in 19 th Century Rationale 2

6 Use of Print media in 20 th Century Rationale 3

7 Use of Electronic media in 21 st Century Rationale 4

8 Medical AirwaysRailways Communication Industries Financial Institutions Agriculture & Farmer ? Rationale 5

9 Poor ratio of SMS to agents Lower level of education of extension agents Short supply of extension agents More number of farmer per extension worker More area to be covered by agents Less number of female extension agents Human Resource of Extension Rationale 6

10 Poor transportation facility to agents Lower pay to extension agents Less avialability of programme cost Poor housing to extension workers Poor communication facility to agents Very little expenditure per farmer Financial Resource of Extension Rationale 7

11 What should I do? Extension Client

12 Market 5 km Land 2 acres Labour 5 members Capital Rs Power Pair of bullock Source of Irrigation Pump set My resources

13 Which choice is best? Which choice is income generating? Which choice requires less labour? Which choice requires less land area ? Which choice is not much affected by season? Which choice requires less input? Fisheries Crops Fruits Piggerey Flowers Poultry Dairy Bee keeping

14 Magazine Television Extension worker Neighbour News paper Friend Who will help me in appropriate decision making? The answer of all these questions is: EXPERT SYSTEM OF EXTENSION

15 Difference between Conventional and Expert System of Extension No.Conventional ExtensionExpert System of Extension 1.Universal approachability of same information is a problem. Universal approachability of same information is possible. 2.Information is given what ever is available without considering needs and resources. Information is chosen based on their needs and resources. 3.No Cost benefit analysisCost benefit analysis 4.Information flow depends on availability of agent Information through Cyber Cafe at any place at any time. 5.Extension agents - less educated and non technical. The experts- knowledgeable and high- tech. 6.Manual & fragmented information. Compact & interconnected information. 7.Out dated system.Recent system.

16 What is Expert System ? An “Expert System” is an intelligent computer programme that uses knowledge and inference procedures to solve problems that are difficult enough to require human expertise for their solution. The knowledge necessary to perform at such a level plus the inference procedures used can be thought of as a model of the expertise of the best practitioners in the field.(Daniel Hunt, 1986)

17 Conceptual Design Expert System of Extension Knowledge Base Domain Expert Knowledge Engineer Knowledge, Concepts, Solutions Data, Problems, Question Structured Knowledge Knowledge Acquisition Module Technical & Extension bulletins Textbooks Facts Research Findings

18 Objectives To categorize agriculture in sub-areas and collect relevant information of these areas to feed into database. To make decision rules to process the information (of selected crops). To design & develop the web based expert system of extension To provide required information to the farmers and extension workers to take decisions before starting the agricultural enterprise.

41 Paddy -Better the plant population higher the yield. -Longer the duration of crop more the yield. -Using Gaze wheel for land preparation yields more. -Changing crop rotation controls weed and enhances soil fertility.

42 Tomato -Plant population per acre should be 9600 to 9700 (9680). -Suitable temperature ranging from degree centigrade. -The best soil is loam and sandy loam gm seed sufficient for one hectare. -The nursery beds should be 65-cm width. -15 cm long seedlings should be transplanted. -First crop should be grown in June-July and transplanted in July- August -Second crop should be grown in November-December and transplanted in January-February.

43 Gladiolus -Corms are most productive during first six years. -Loam or Sandy loam soil best suits it. -Fertility condition of soil to be assertained after soil testing. -The time from planting to bloom varies from 70 to 90 or more days. -Plant large bulbs 4 to 6 inch deep, medium 3 to 4 inch deep and small bulbs 2 to 3 inch deep. -Rows should be spaced from 20 to 36 inches apart. -Corms may be spaced only 2 to 3 inches apart in the row.

44 Mushroom -Mushroom do not contain chlorophyll, therefore, depend upon other plant material for their food. -Picking is done by twisting the mushroom gently so that it is pulled out without leaving any stub. -Mushroom should be harvested when the cap begins to fold and has attained a diameter of 8-10 cm. -It is possible to get 800 gm to a kilogram per kg of the dry substrate. -The packed bags are incubated in well-ventilated room where uniform temperature of 25 degree centigrade is maintained.

45 Mango -Firm ripe mangoes that are just developing colour are picked and ripened in straw. - R ipen fruits are selected daily from the lot. -The slices are placed in 2 per cent common salt solution to prevent their enzymic browning. -Plain cans should be used.

46 Mustard -Sowing is to be done within10-20 Oct. as pure crop to control aphids. -There is risk of Aphid attach if sown after 20 Oct. -Thinning is one most required intercultural operation. -Better the pant population higher the yield. -Paleva before sowing enhances germination and yield. -Mustard cultivation controls weeds in the field for the next crop. -Requires less input and labour. -It suits best in less irrigated water and labour areas.

47 Pea -Early varieties take days. -Mid-season varieties take days. -Late season varieties take days kg seed per hectare for late varieties. -100kg seed per hectare early varieties
