DASGUPTA ARTICLE CHRONICLE : SUMMARY : Effect on adoption and area inexpension of intervented technologies study in five village of Karge Received: Panchyat of Mandar Block of Ranchi District, Jharkhand result showes that the demonstrating and experimenting 18.10.2012; farmers had adopted relatively a large number of technologies compared to participating farmers.Majority of the Revised : demonstrating farmers (87%), experimenting farmers (83%) and participating farmers (84%) had adoption index 28.05.2013; scores between 26 to 75 per cent. No significant differences among three categories of respondents were found Accepted: with respect to their adoption scores. Out of six technologies demonstrated, four were found to be adopted by above 50 per cent of the respondents except two i.e. soil application of bleaching powder and lindane dust and use of wilt 03.06.2013 resistant brinjal varieties Swarnshree. However, the two technologies were found to be adopted by above 50 per cent of the experimenting farmers.The co-efficient of correlation between caste and family size with adoption score was found to be positive but non-significant with respect to the three categories of respondents. As an effect of adoption of assessed i.e.verified technologies under well-endowed production systems, area under tomato, cauliflower and capsicum increased to an extent of 1466.66, 2350 and 650 per cent, respectively among demonstrating farmers, whereas, 1340, 866 and 933 per cent among participating farmers, respectively. Similarly under small production systems due to effects of adoption of demonstrated refined technologies, area expansion under tomato, brinjal and cauliflower was recorded to an extent of 1300, 1200 and 966.66 per cent, respectively among experimenting farmers and 1600, 1066 and 755 per cent among participating farmers. Rate of diffusion of the refined technologies was around 30 per cent in both well-endowed and small production systems. Spread effect was relatively higher KEY WORDS : (41.85%) in well-endowed production systems compared to the small production systems (33.4%).

Demonstrations equipped interventions related to tomato, -brinjal, with organization of training on related cauliflower, capsicum were assessed and refined interventions and field days were conducted for under well-endowed production system through popularizing the technologies in both the small verification trails (VTs) and in small production and well-endowed production systems. The system through on farm trails (OFTs).

HIND AGRICULTURAL RESEARCH AND TRAINING INSTITUTE R.K. SINGH , S.K. DUBEY, R.P. SINGH ‘RATAN’ AND D. DASGUPTA Adoption is an important indicator for measuring the population of different religions, castes and tribes. The village success of extension education activities like demonstration is predominantly inhabited by the Munda tribe. It is situated and training followed by technology assessment and refinement. at a distance of 1.5 km. from Karge panchayat hq. The total In this section, an attempt was made to analyse the level of number of households in the village is 210. adoption of selected vegetable production technologies as well as to study the association between adoption scores and selected Keskani-Kumbatoli : characteristics of the respondents. Keskani-Kumbatoli is a very small village having 48 households of different castes and tribes. It is at about 2 km RESOURCESAND METHODS from Karge panchayat hq situated adjacent to Chatwal village. The villages under study : Research design and sampling procedure : The study was undertaken in the five purposively A combination of research designs, namely, analytical selected villages of Karge panchayat in Mandar Block, and ex- post - facto was used in the study. namely, Karge, Rege, Hatma, Chatwal and Keskani- Three categories of respondents, namely, demonstrating kumbatoli. The rationale behind selection of the villages was farmers, experimenting farmers and participating farmers their adoption under Institution - Village Linkage Programme were selected from each of the five adopted villages related of Birsa Agricultural University Center, where to demonstrations, verification trials and on-farm trials demonstrations and on farm trials (OFT) were conducted for conducted on important vegetables, viz., tomato, cauliflower, assessment and refinement of technologies. A brief capsicum and brinjal. Rationale behind selecting these description on each selected village is as follows: vegetable crops were their predominance in the study villages. Karge : All the demonstrating farmers (60) experimenting Karge is situated at a distance of 5 km towards North farmers (60) and 25 per cent of the participating farmers from Mandar Block hq. It is a big village consisting of six from the selected villages (150) constituted the sample for hamlets i.e. Karge-Satpara, Karge-Oranotoli, Karge-Riptin, data collection. Thus, the whole sample consisted of 270 Kare-Karamdaha, Karge-Behratoli and Karge-Nayatoli. The respondents. Selection of demonstrating farmers and village is having mixed population. experimenting farmers was done on the basis of purposive sampling technique and selection of participating farmers Rege : was done on the basis of simple random sampling technique. Rege is relatively a small village having 62 households Village-wise distribution of respondents has been presented of different castes. Rege is situated at 1 km. from Karge in Table A. village on the left side of Mandar-Burmu metalled road. Adoption of intervened technologies : Hatma : An adoption scale was developed to measure the extent Hatma is a medium size village having 126 households of adoption of intervened technologies by the respondents. predominantly inhabited by munda tribe. The village is A list of intervened technologies of vegetable cultivation was situated at a distance of 2 km from Karge panchyat hq towards prepared. Respondents were asked to indicate the intervened north falling both sides of the Mandar-Burmu mettalled road. technologies adopted by them with their extent. The level of adoption of respondents and overall Chatwal : adoption of intervened technologies were computed in the Chatwal is relatively a large village having mixed following manner: Table A : Village-wise distribution of different categories of respondents Experimenting farmers Demonstrating farmers Participating farmers Total Sr.No. Village (n=60) (n=60) (n=150) (n=270) 1.

Update, 8(3) Aug., 2013 : 336-342 337 Hind Agricultural Research and Training Institute STUDY THE ADOPTION & AREA EXPENSION OF INTERVENT TECHNOLOGY THROUGH OFT & VT UNDER MANDAR BLOCK OF RANCHI DISTRICT The adoption score assigned to each respondent was Effect on expansion of area under intervened summed up and the mean score of adoption (X = 6.98) and technologies: standard error (SE = 2.42) were computed. Adoption was Effect of expansion of area was computed in terms of categorized into three levels i.e. low level of adoption if the area under intervened technology out of total area under total score of an individual respondent was below X-SE cultivation of related crops. The following formula was used (5.98), medium level of adoption if the score varied from for computation: X+SE to S+SE (5.98 to 8.62) and high level of adoption if individual score was above X+ SE (8.62). OBSERVATIONSAND ANALYSIS In order to determine the overall extent of adoption of intervened technologies following procedure was adopted. The results of the present study as well as relevant Adoption quotient (AQ) was worked out for each respondent discussions have been presented under following sub
