What is expert system l.jpg
What is Expert System ? Extension

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)

Paddy l.jpg
Paddy Extension

-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.


Tomato l.jpg
Tomato Extension

-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.


Gladiolus l.jpg
Gladiolus Extension

-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.


Mushroom l.jpg
Mushroom Extension

-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.


Mango l.jpg
Mango Extension

-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.


Mustard l.jpg
Mustard Extension

-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.


Slide47 l.jpg
Pea Extension

-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
