  2. Research Team • Dr.Ram Bahal (PI), IARI • Dr. (Mrs.)Monika Wason (Co- PI), IARI • Sh. Sudeep (CCPI), IASRI

  3. Rationale: Expert System of Extension

  4. Rationale 1 Introduction of Extension • 1866 Great Famine of Bengal & Orissa • 1861-1941 Rabindranath Tagore-Self help and Mutual help • 1869-1948 Mahatma Gandhi-Improvement in their inner man • 1880 Famine Commission • 1901 Famine Commission • 1928 Royal Commission To Meet the Food Need (Quantity) Quality , Precision and Economic gain

  5. Rationale 2 Personal & Group Contact in 19th Century

  6. Rationale 3 Use of Print media in 20th Century

  7. Rationale 4 Use of Electronic media in 21st Century

  8. Rationale 5 Railways Airways Agriculture & Farmer ? Financial Institutions Industries Communication Medical

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

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

  11. Extension Client What should I do?

  12. Labour 5 members Land 2 acres My resources Source of Irrigation Pump set Power Pair of bullock Capital Rs. 5000 Market 5 km

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

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

  15. Difference between Conventional and Expert System of Extension

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

  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.

  34. 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.

  35. Tomato -Plant population per acre should be 9600 to 9700 (9680). -Suitable temperature ranging from 18-28 degree centigrade. -The best soil is loam and sandy loam. -350-400 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.

  36. 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.

  37. 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.

  38. Mango -Firm ripe mangoes that are just developing colour are picked and ripened in straw. - Ripen 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.

  39. 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.

  40. Pea -Early varieties take 55-60 days. -Mid-season varieties take 57-90 days. -Late season varieties take 100-110 days. -70-75 kg seed per hectare for late varieties. -100kg seed per hectare early varieties
