(Department Of Agricultural Extension, College Of Agriculture, Vellayani, 2015) Sujitha, P S; KAU; Seema, B
The study entitled “Technology assessment of plant protection practices of economically dominant crops in homegardens’' conducted in the Thiruvanathapuram district of Kerala state covering 100 homegardens having an area more than 25 cents were selected from five Agroecological units (AEU) viz.. Southern coastal plains, Southern central laterites, Southern high hills, Southern central foothills and Southern laterites. Twenty operational homegardens from each of the five panchayats belonging to the selected AEUs were chosen making the total sample size to 100 respondents. Delineation of economically dominant crops in homegardens, levels of adoption of selected KALJ plant protection practices, technology need assessment, constraints in adoption of plant protection practices and suggestions as perceived by the farmers were the major objectives of the study. The independent variables selected through judges rating were age, education, occupation, effective homegarden area, family size, farming experience, information source utilization, rational orientation, extension participation, knowledge, evaluative perception on sustainability of plant protection practices and economic motivation. The independent variable selected was adoption of selected KAU plant protection practices. The economically dominant crops identified were coconut, banana, tapioca, pepper, vegetables, yams and colacasia and arecanut respectively in the homegardens. The overall level of adoption of selected plant protection practices showed that majority (70%) of the respondents had medium level of adoption followed by 16% having high level and 14% low level of adoption. The adopter category curve delineated for the overall adoption showed that 45% of the respondents fell under early majority followed late majority (21%), laggards (16%), early adopters (14%), with no innovators. Differences in adopter categories were observed for different crops. Age, information source utilization and extension participation were found to have significant positive relationship with the dependent variable adoption of selected plant protection practices of KAU. In coconut, banana, tapioca and arecanut ease in operation was perceived as the most preferred plant protection criteria in homegardens. The result showed that 45% of the farmers found the preferred KAU plant protection practices to be useful however only 40% of the respondents felt it effective. Of the 17 ITK plant protection practices, four were specific to vegetables and banana each. Two were specific to plant protection of coconut and six of general practices. Major constraints identified were, plant protection chemicals not effective in their recommended dosage, followed by climatic influence on pest and incidence and non availability of plant protection chemicals. Suggested refinement in plant protection technology as perceived by the homegarden farmers were in generating of ecofriendly and organic plant protection measures that are suitable for homegardens followed by timely availability of plant protection inputs and generation of more pest and disease resistant varieties.

Impact of the rice variety,Uma (Mo16) on farmers
(Department of Agricultural Extension College of Horticulture, Vellanikkara, 2015) Neshva; KAU; Sakeer, Husain
Rice is the staple food of the people of Kerala, and traditionally, the cultivation of rice has occupied pride of place in the agrarian economy of the state. Palakkad and Alappuzha are the two major rice-producing districts of Kerala. About 600 varieties of rice were grown in the sprawling paddy fields of Kerala. One of the most popular rice varieties of Kerala is Uma (Mo.16) developed by the Rice Research Station, Moncompu of Kerala Agricultural University and it occupies more than 60 percent of the paddy cultivation area in Kuttanad region. The study intended to analyse the attributes of the rice variety, Uma (Mo16) vis-a-vis other rice varieties as perceived by farmers and to assess the socio economic impact of Uma on rice cultivating farmers. The study was confined to Kuttanad tract of Alappuzha. An ex-post facto research design was adopted for the study. Five padasekharams were selected through simple random sampling method, and from each padasekharam, 20 farmers cultivating the rice variety, Uma were selected, thus constituting a sample size of 100. A pretested structured interview schedule and PRA techniques were employed for data collection. The results revealed that tolerance to pests and diseases was ranked first with an index of 94.60 followed by non-lodging nature of plant (92.60), non-shattering nature of panicle (86.70), amenability to mechanisation (75.40), millers’ preference (49.60) and cooking quality (42.00). Varietal comparison of other rice varieties prevalent in Kuttanad area with ‘Uma’ using PRA technique revealed that ‘Uma’ was perceived as the superior variety with a score of 520.42 followed by Jyothi (443.95) and Prathyasa (418.72). Results of SWOC analysis done using PRA techniques, revealed that among the strengths, ‘high yield’ ranked first with an index of 98.80 followed by ‘tolerance against pest and disease incidence’ (96.00), ‘high grain weight’ (91.00), ‘high tillering capacity’ (89.00) and ‘high seed dormancy’ (85.2). However, low cooking quality (96.10) and less preference of the rice variety by millers (94.2) were emerged as the major weaknesses. It was, also found that all the respondents were continuously cultivating ‘Uma’ without any varietal shift. Majority (56 per cent) of the farmers had been continuously cultivating the rice variety, Uma for the past 15-17 years. With regard to the social impact on farmers, it was revealed that social participation has improved significantly. Similarly, information seeking behaviour has also increased positively, where as labour use has decreased significantly. However, there was no significant change in the communication behaviour of farmers. As regards economic impact, ‘annual income’, ‘family expenditure’, ‘savings’ and ‘asset creation’ of farmers have increased significantly after cultivation of the rice variety, Uma as compared to pre-Uma period. Indebtedness of farmers was also found to have decreased. Thus, the rice variety Uma could make a very promising impact on the socio- economic variables of farmers. Regarding comparative income advantage of Uma, it was found that this variety had an income advantage of Rs.38000/- per ha over the variety, Jyothi and Rs.95000/- per ha over local varieties. Thus, for a single puncha season, Uma had given an additional income of Rs.104.30 crores as compared to Jyothi and Rs.260.75 crores as compared to local varieties, in Kuttanad tract of Alappuzha alone. With regard to constraints faced by Kuttanad farmers, ‘non-availability of labour’ was ranked first with an index of 98.60 followed by ‘high cost of inputs’ like fertilizers and pesticides (89.60), ‘vagaries of weather and climatic conditions’ (81.20) and ‘non fixing of floor price on time’ (70.80

Tools and services for m-extension: problems and prospects
(Department of Agricultural extension, College of Horticulture, Vellanikkara, 2016) Nagam Kusuma, Kumari; KAU; Sakeer Husain, A
Information and Communication Technology (ICT) has now become an integral part of the development process. Mobile phones added speed to the ICT revolution by converging the services to create, store, access and share information anytime and anywhere making them all-in-one magical device. It has become such an integral part of everyday life that it estimated 7 billion subscriptions (International Telecommunication Union, 2016) i.e. 95 per cent of the world’s population. Rapid growth of mobile telephony and the development of mobile phone applications offer services to users that extend well beyond voice and text communications, which can effectively be utilized by the extension personnel for information dissemination and transfer of technology. Utilizing such new applications and services on mobile phones helps the extension personnel for speedy, accurate and timely supply of information to the farmers in various aspects related to agriculture and allied sectors. The present study attempted to analyse the awareness, extent of knowledge, extent of utilization and satisfaction of extension personnel on m-tools. It also explored the constraints perceived by the agricultural extension personnel in using m-tools and formulated strategies for effective m-extension in Kerala. The study was conducted among 150 agricultural extension personnel selected randomly from five districts; which were selected from five agro-climatic zones of Kerala. Data were collected by using pre tested-structured interview schedule. Contemporary mobile apps in agriculture suited to Indian conditions were identified based on ratings, and after downloading them, they were analysed for its contents on the specific information provided by them. Accordingly they were catalogued. The personal profile of the agricultural extension personnel revealed that 53.3 per cent were under middle age category ranging from 35-45 years. It was found that a greater proportion (63.3%) of the respondents were female. With regards to their educational status, more than half (56%) of them possessed a degree as their basic education whereas with reference to agricultural education, 32 per cent had done a certificate course in agriculture followed by 31.3 per cent with B.Sc. (Ag/Horti) graduation. Exactly 31.4 per cent of them had more than 15 years of experience as extension personnel in the State Department of Agriculture. In case of adopting new technologies majority (40%) of the extension personnel were found as imitators, which revealed that they preferred to take their own time to adopt new technologies. Majority of the extension personnel showed medium level of attitude towards m-tools (77.4%) and medium level of occupational commitment (71.3%). The ICT profile of the extension personnel revealed that 64.7 per cent of them had not attended any e-literacy training programmes whereas cent per cent had not attended mliteracy trainings. Mobile phone was the most frequently used gadget as it was owned by cent per cent of the extension personnel. Internet connectivity was good and sufficient for accessing various m-tools which secured a mean score of 3.54. Most (84%) of the extension personnel were aware of Kisan Call Centre when compared to other m-tools. In case of extent of utilisation, most of the respondents were not making use of m-tools but those who were making use of them showed a good satisfaction level. Among the constraints perceived by the extension personnel in using m-tools, unavailability of user friendly m-apps in Malayalam language was identified as the major constraint followed by non-availability of mobile phone networks in rural areas, lack of exposure to m-education among extension personnel, low level of e-readiness by the extension personnel/organizations and so on. Majority (82%) of the extension personnel opined that m-apps were necessary for effective extension work and the information required by them through m-tools comprised of information on pest and disease identification and control measures, location specific weather and marketing aspects, availability of quality inputs and so on. In order to facilitate effective m-extension in Kerala, there is urgent necessity for organising e-literacy and m-literacy training programmes. Similarly there is a need to modify the G.O. No. 14409/R2/2011/P& ARD which stated a restriction on the use of mobile phone in work place. Mobile voice messages to language minorities focus on developing user friendly apps in Malayalam, providing official smart phones to extension personnel, exposure of extension personnel on m-education and policy level decisions to make the agricultural extension organisations e-ready are some of the strategies to be considered for effective mextension in Kerala.

(Department Of Agricultural Extension, College Of Agriculture, Vellayani, 2013) Sreejas, S; KAU; Sakeer Husain, A
The study entitled “Livelihood Analysis of Kattunaikan tribe of Wayanad” was conducted to analyse Livelihood capital and to study the Extent of deprivation of Kattunaikan tribe of Wayanad. Their Social exclusion, Attitude towards developmental interventions, and the Constraints experienced by them in livelihood security were also studied. The study “Livelihood Analysis of Kattunaikan tribe of Wayanad” was conducted in three developmental blocks of Wayanad district namely Sulthan batheri, Mananthavady and Kalpetta. The selection of number of settlements from each block was done based upon the population of Kattunaikans in each block. Three settlements Random sampling technique was followed in the selection respondents. From each settlement, 20 family heads were randomly selected. Total sample size for the study was 120. The dependent variables selected for the study were Livelihood capital, Extent of deprivation and Social exclusion. Independent variables were selected which includes Age, Landholding, Family size, Value orientation, Political orientation, Change resistance, Modernization, Alcoholism and Attitude. The correlation between dependent and independent variables was studied using correlation analysis. Constraints experienced in livelihood security were also recorded from a number of identified statements as perceived by the tribes people. The data were collected using pre-tested structured interview schedule prepared for the study. The statistical tools like mean, percentage analysis and correlation analysis were used to analyse the data. The salient findings are presented below. Majority of the Kattunaikans (55%) belonged to young category. Most of the Kattunaikans( 52.5%) had only upto 10 cents of land holding. More than 30 per cent of the Kattunaikans had six members in their family. Majority (62.5%) of the respondents were traditional. Ninety two point five per cent of the respondents were politically oriented. Majority (92.5%) of the respondents were least resistant to change. Forty five point eight per cent of the respondents were non users of alcohol. More than 90 percent of the respondents were modern. Majority (69.2%) of the respondents had a positive attitude towards developmental interventions. In the case of Human capital, it was observed that 50.8 per cent of the respondents were illiterate. More than three fourth (85%) of the respondents were included in the high hygiene category. Majority (63.3%) were having high addictive behaviour. More than half (61.7%) of the respondents were having poor health care seeking behavior. Majority (92.5%) of the respondents were taking unbalanced diet. Human capital was estimated as 51.6. With respect to Physical capital it was found out that More than 50 per cent of the respondents were having concrete houses. Exactly 42.5 per cent of the respondents were having houses with good condition. More than 40 percent of the respondents were having Material possession of only 1000-5000 rupees. Forty per cent of the respondents were having no livestock possession. More than half (69.2%) of the households have in-house toilet facility. Sixty per cent of the respondents were having electric connectivity in their houses. Majority (74.2%) of the respondents have to go up to 500m for collecting water. Physical capital was estimated as 59.9 Annual income of the respondents ranges from Rs.6200 to Rs.96000.The average annual income was found to be Rs 22435/-. The mean expenditure was found out as Rs.20605.83/-. Only 24.2 percent of the respondents were having savings. Only 4.2 percent had a debt for an average amount of Rs. 9000. Financial capital was estimated as 59.6. The poverty gap was estimated as Rs. 20242. More than 90 per cent of the respondents are trapped in poverty. The study indicated that53.3 per cent of the respondents belong to the low social participation category. Majority (60.9%) of the respondents were having a good social relationship. Social capital was estimated as 50.6 With respect to gross cropped area, 50 per cent of the respondents were in the category of ‘very low’. More than half (56.7%) of the respondents depend heavily on natural resources for their livelihood. Natural capital Index was found out as 35.9. The Livelihood Capital Index was obtained as 51.5. More than three fourth (77.5%) of the respondents were having medium livelihood capital index The respondents were mostly deprived of cultivable land in the forest, income, land, employment, recreation, nutrition, clothing and food. Nearly half (50.84%) of the respondents were in the low social exclusion category. The relationship between independent and dependent variables revealed that landholding showed positive significant relationship with Livelihood capital. Attitude showed negative significant relationship with Deprivation. Change resistance showed positive significant relationship and modernization showed negative relationship with social exclusion. Extent of deprivation is negatively and significantly correlated with Human capital, Social capital and Financial capital. The most important constraint faced by the tribes people is the absence of title deeds. Landless and inadequate land for cultivation, alcoholism and smoking, growing unemployment, wild animal menace and scarcity of drinking water were the other important constraints faced by the Kattunaikan tribe in livelihood security. Kattunikans have to be developed by considering their culture and tradition. From the study it is clear that even though they were having an inclination towards their values, they are getting modernised. It can be said that they are in a transition stage. They are less empowered. Empowerment through education is essential. Illiteracy, income deprivation and associated ill effects are very much prevalent among them. So educational development by utilizing the educated Kattunaikans as teachers, establishment of value addition units of forest produces and in the settlements especially for women and contributory savings schemes (through co-operative societies) have to be established.

Social exclusion of tribal agricultural labourers; the case of paniya tribe of wayanad
(Department Of Agricultural Extension, College Of Agriculture, Vellayani, 2013) Anoop, R J; KAU; Anil Kumar, A
Paniya tribes of Wayanad are the most backward among the vulnerable groups of Kerala. Their economy is traditional in nature, depending mainly on land and forest. On accounting the land utilisation pattern of Wayanad district has drastically changed owing to massive in-migration of people from the plains to these areas in search of land for cultivation and for starting plantations. Inappropriate implementation of schemes and lack of adequate technological support resulted in a drastic decline in the economy of the tribespeople resulting in their exclusion and deprivation. This study entitled "Social Exclusion of tribal agricultural labourers: A case of Paniya tribe of Wayanad" was an attempt to analyse the Social exclusion and their deprivation. The study was conducted in Wayanad district of Kerala. A sample of 90 tribespeople were selected randomly from three blocks of Wayanad district viz, Panamaram. Noolpuzha and Kaniyambetta. The study indicated that most of the tribespeople belonged to the middle age group, 48 per cent of the tribespeople. Among the respondents 82 per cent were illiterate and only 9% of the tribes had schooling. 89 per cent of the tribespeople had high level of environmental orientation and 100 per cent of them consume alcohol. The study revealed that the Paniya tribespeople had landholdings only up to 10 cents. 76% of the tribespeople had an area of 4-6 cents. It was identified that 67 per cent of the tribes do not use the land on lease and 21 per cent of the tribes had leased landholding of 3-4 cents. From the study it was found that 47 per cent of the tribes had an income ranging from Rs.3001-Rs.4000. The indebtedness as indicated 50 per cent have a debt amount ranging Rs.1000- Rs.2000. From the result it was revealed that 84 per cent of the tribes live in brick or laterite walled tile house. 65 per cent of the tribespeople live in a poor conditioned home. Classification of tribespeople based on social exclusion reveals that 54 per cent of the tribespeople have felt social exclusion and 46 per cent of them is do not feel they are socially excluded. On classifying the tribespeople based on deprivation it was found that 100 per cent of the Paniya tribespeople felt that they were deprived of the social functioning.

Decision support system on nutrient recommendations for rice - an end - user assessment
(Department of Agricultural extension, College of Horticulture, Vellanikkara, 2011) Swafah, C; KAU; Ahamed, P
Effective transfer of technology is very crucial in agricultural development of any nation. This is a challenge particularly for countries like India where diverse farming, highly fragmented land holdings, large number of farmers, several official languages are involved in the process. As a result only a fraction of farming community is largely benefited by utilizing the new technological advancements. The information needs of agriculture at large are diverse and complicated. Reaching right information at right time is a major challenge through conventional extension methods. Thus introducing modern information and communication technology is a better option. It is an established fact that fertilisers contribute up to 50 percent to total production. However, the prevailing communication gap between scientific groups and farming communities is making the task highly difficult for practical implementation of official fertilization practices in the field. Farmers are not fully aware of nutrient doses Vs fertiliser quantities resulting in improper fertilization practices in the field. Such improper practices are leading to imbalance in nutrient use and finally leading to soil fertility degradation. The major requirement in this communication process is compilation, classified arrangement and proper management of diverse information on various fertilisers, nutrient doses for a wide range of crops and cropping systems. This has to be done in such a way that the specific information is quickly accessible and easily translated in to a practical recommendation. Realizing this, Kerala Agricultural University through a collaborative research programme with the Indian Council of Agricultural Research has come up with a decision support system entitled ‘Nutrient Recommendation Syatem for Rice’ (NRSR). The NRSR is a generic decision support system for rice capturing the selected seven rice cropping systems of Kerala, expected as an user friendly software package for choosing appropriate or available manurial and fertilizer options aiming sustainable yields and reasonable farmer’s profit. The NRSR will aid as a decision making tool for calibrating the required dose of fertilizers for a particular area of land in a specific cropping system, specific to soil test data and arriving at the total cost of each manures and fertilizers. This package supported with touch screen option, will act as an efficient extension tool for the agricultural officers, rice scientists, and other extensionists in decision making and prescribing appropriate nutrient management options (Ganesan, 2006). Developing a DSS software is a time consuming and resource intensive project. So a systematic user-participatory assessment exercise, prior to its large scale recommendation is imperative. The study was conducted to identify the gaps and to assess the technical quality, information efficiency, and userfriendliness as perceived by end- users. The research was conducted among the agricultural officers of Thrissur and Palakkad districts of Kerala as they were two leading districts in rice cultivation in the state. The respondents from both the districts agreed that it could save the time of user in getting solutions for field problems, and also it is cheaper when compared to the process of seeking human expertise. An increase in knowledge level of respondents regarding nutrient management aspects of rice cultivation also happened after giving exposure to NRSR. The main suggestions obtained for the refinement of software were as follows: 1.The fertiliser calculator provided in NRSR is capable of performing straight fertiliser calculation only, and unable to calculate fertiliser dose for complex fertilisers like Factomphose which is commonly used and easily available nitrogen source. So it should also be included in the system. 2. The fertiliser calculator in the system was designed in such a way that it is according to lowmedium- high status of soil fertility, it should be sensitive to numerical data of soil test for getting more accurate results. 3. NRSR should be developed in local language so that maximum users could benefit. 4. NRSR should be linked and updated according to weather forecast and given in the web to access by all kinds of users at any time. 5. More clear photographs should be included to diagnose the symptom easily. 6.Demo videos for seed treatment, mat nursery preparation and other operations in rice should also included in the system. 7. The latest rice varieties with specific charecteristics and photographs should also be included in NRSR.

Analysis of constraints and strategies for scaling up of precision farming in Kerala
(Department Of Agricultural Extension, College Of Agriculture, Vellayani, 2013) Sadam, Hanjabam; KAU; Prakash, R
The study entitled “Analysis of constraints and strategies for scaling up of precision farming in Kerala” was an attempt to critically analyse the attitude of the farmers towards PF technology, assess the extent of adoption, identify the constraints and formulate strategies for scaling up of PF in Kerala. Ninety farmers consisting of 60 precision farmers (banana and vegetables) and 30 conventional farmers were randomly selected from Chittur block in Palakkad district of Kerala. 12 independent variables, two dependent variables and 30 constraints were studied and analysed with the help of different scales and techniques. A well-structured pre tested interview schedule was used for collection of data from the respondents. The study indicated that 80 per cent of the precision farmers belonged to old age group. Majority of the farmers had more than 25 years of farming experience. Precision farmers had a higher level of information seeking behaviour, risk and scientific orientation. More than 50 per cent of the precision farmers had attended more than 10 trainings. Conventional farmers had better market perception and were more economic orientated. However precision farmers were more innovative. Majority of the respondents had moderately favourable attitude towards PF practices and had medium level of adoption. The most important constraints experienced by both categories of respondents were rainfall and other meteorological problem and high cost of inputs. Non-availability of inputs, lack of technical skill , inadequate size of landholdings , lack of marketing facilities, heavy fluctuation in commodity price, high labour charges were other constraints of importance. Provision of a panel of multidisciplinary specialists for full time technical advice and a technical officer for implementation of the scheme was one suggestion. Developments of a market support system, F1 hybrids suiting to Kerala etc., were other measures. Besides, some extension strategies like shifting of PF from technology push to application driven approach, providing technologies through rental services , strengthening the relationship among IT, ICT, biotechnology and PF , development of a Decision Support System ( DSS) etc., are suggested which may help to scale up PF in Kerala.

Farm telecast in Kerala - a critical appraisal
(Department Of Agricultural Extension, College Of Agriculture, Vellayani, 2013) Sobha, S; KAU; Seema, B
This study entitled ‘Farm Telecast in Kerala – a Critical Appraisal’ was carried out in fifteen panchayats of Thiruvananthapuram, Kollam and Alappuzha districts. The main objectives of the study were to study the farm telecast viewing behaviour of farmers and correlate their socio – psychological characteristics with it, content analysis of agricultural programmes, compare the programmes of different Malayalam channels on the basis of content, mode of telecast, time, duration and frequency .Suggest steps to improve the efficiency of farm programmes. The data were collected using the pre tested interview schedule from 90 respondents and analysed using suitable statistical tools. The suggestions for improving the programme were collected from 60 respondents comprising of agricultural scientists, extension agents, producers and members of post-production team. The major findings of the study indicate that 51.11 per cent of the farmers surveyed were viewing the agricultural programmes more than twice a week. Majority (68.89%) of the farmers completely and 62.22 per cent keenly viewed all the programmes. Majority of farmers were taking down notes of programmes. Most of the respondents (60.44%) sometimes discussed the programmes with other progressive farmers, extension agents and friends. Majority of the respondents were either regularly or sometimes clarifying their doubts with extension personnel’s or progressive farmers. Most of the farmers(53.33%) had medium level of viewing behaviour. Majority of the farmers preferred to view 45 minutes programme in the evening for more than five days a week. Success story was the most preferred mode. Above fifty per cent of the farmers preferred viewing the agricultural programmes telecast by Doordarshan, Asianet, Kairali and Jai hind channels in that order. Age, educational status, occupation, farming experience had no significant relationship; innovativeness, economic motivation, risk orientation, cosmopoliteness, scientific orientation, achievement motivation, social participation, mass media exposure, extension contact, extension participation and information source utilization were significantly and positively related to viewing behavior. Sixty five per cent of the variation in viewing behaviour was accounted by six variables. Content analysis revealed that agriculture was the main subject matter followed by animal husbandry. Documentary and success story modes were used with government officials and farmers as the main information sources. Majority of the farmers perceived the farm programmes to be fairly effective. Strategy for improvement of the farm programmes include telecasting a wide range of location specific and need based programmes in demonstration and success stories modes with increased participation of farmers. Telecast 45 minutes to one hour programme in the evening between 7pm - 9pm with prior announcement of the programme details as done by AIR. Based on the objectives of the study it can be concluded that majority of the farmers perceived that the farm programmes telecast by Doordarshan, Asianet, Kairali and Jai hind TV to be fairly effective and they preferred to have 45 minutes to one hour duration programme in success story/demonstration mode on all days of the week between 7-9 PM on current topics. The implication is that the audience research wing of the channels needs to be strengthened so that the programmes can be tailor made to suit the needs of the farming community.

Innovations in e-agricultural extension technology (e-AET): diffusion and adoption of agri-expert systems among extension professionals in Kerala
(Department Of Agricultural Extension, College Of Agriculture, Vellayani, 2014) Modem, Ravikishore; KAU; Allah, Thomas
The present study entitled 'Innovations in e-Agricultural Extension Technology (e-AET): Diffusion and adoption of agri-expert systems among extension professionals in Kerala' was conducted at Thiruvananthapuram district during 2012-2014 covering 100 extension professionals. Expert systems allows the use and application of information technology and communications technology (lCT's) to access and obtain information related to agricultural production, marketing, distribution, and prices, and the results of agricultural research, innovations, to raise the level of agricultural production and benefit the farming community. The present study, therefore, is with the objective to conduct a systematic appraisal of existing expert systems in agriculture vis a vis their diffusion among the extension professionals. The findings demonstrate that most of the extension professionals either in State Department, NGO or University have positive attitudes towards expert system. Age, training, innovativeness, retrievability, relevancy, format clarity, information content, availability, accuracy and timeliness affect extension professionals' attitudes. Based on respondent's stage in the adopter categorisation with reference to expert systems, it was found that 10 per cent of the sampled respondents belonged to innovators category, 19 per cent respondents belonged to early adopters' category, 32 per cent respondents belonged to early majority category, 24 per cent respondents belonged to late majority category and 15 per cent respondents belonged to laggards' category. Effectiveness index of expert system applications was worked out using seven statements and the results showed that pedagogy (as a means to effective learning through expert system) having highest effectiveness index. The findings demonstrate that most of the respondents belonged to middle age category, holding with master degrees; attended training on lCT. It was also found that most of the respondents having high innovativeness and accessibility, forinat clarity and information content of the expert system perceived as high. Availability, retrievability, relevancy, timeliness, accuracy and effectiveness index of expert system perceived as medium by the respondents. Hence, the study undoubtedly exhibited affirmative reaction from all three categories of respondents on the applications of expert systems in the field of agriculture, because local information resource centers are gaining importance with computers carrying expert systems to help fanners to make decisions.
