Diffusion of technology changes the structure of the social system. Technology is considered as one of the essentials of the agricultural development process and diffusion of technology plays a pivotal role in the process of agricultural development. Diffusion is the spread of innovations through communication channels over a period of time. All the individuals in a social system do not adopt an innovation or technology at the same time because of personal, socio-psychological, situational, cultural and economic factors. Of late, emphasis is being given to the dissemination of agroforestry technologies in order to maintain balance in the ecology. Hence a field study was undertaken in order to understand the diffusion process in relation to eucalyptus, and to find out the factors influencing the rate of adoption of eucalyptus in Bangalore rural district of Karnataka. The study was conducted in 10 randomly selected villages where all the farmers had adopted eucalyptus plantation. The data was collected through structured and pre-tested schedules. The personal interview method was followed for data collection.
The study revealed that adoption of eucalyptus species has taken 52 years to reach all the farmers. In a span of 40 years, technology had reached only 43% of the farmers. While in another 12 years it has reached the remaining 57% of the farmers. Farmers perceived that the technology has advantages over the agricultural crops, is compatible with soil type and rainfall patterns and is less complex. Factors like education, size of land holding, material possessions, social participation, extension participation, mass media participation, readiness for innovation, management orientation and scientific orientation have contributed significantly to the rate of adoption of this technology. Constraints encountered in the production and marketing of eucalyptus, along with strategies to overcome these are also discussed in the main paper.
Social change is a process by which alteration occurs in the structural and functional units of a social system and involve three sequential stages in the process namely invention, diffusion and consequences. According to research studies, the enough technologies are available and they have brought lot of changes in the system. Of late, lot of emphasis is given on the diffusion of forestry technologies. Due to the impact of different forestry development programmes, the farmer stated growing some agroforestry species especially in the rural-urban areas. The Eucalyptus species were introduced in Karnataka State, India during the year 1946 especially in the rainfed areas as its use are manifold and comes well in the low rainfall areas. The species slowly started trickling down into the system. In addition, forest department efforts also facilitated the spread of this tree species. All these, have yielded results especially in ruro-urban areas. Hence, a field study was undertaken during this year 2001 in the state of Karnataka with the following objectives.
1. To investigate diffusion of eucalyptus species
2. To assess the perceived attributes of eucalyptus species, and
3. To study the characteristics of farmers growing eucalyptus species.
The villages of Karnataka State, India where in all the farmers are growing agroforestry species were listed. From among the list of villages, five were randomly selected. From the selected villages, all the farmers were interviewed with pre-tested schedule. This sample constituted 150 farmers. The data was collected by personal interview method and then tabulated and analyzed using the appropriate statistical tests.
The findings of the research study revealed that the 53 years were required to make all farmers to adopt eucalyptus species in the selected five villages. The results also revealed that in a span of 40 years technology could reach only 43 per cent of the farmers while in another 12 years it has reached the remaining 57 per cent of the farmers. Thus, the year 1988 can be considered as the 'take off' year for the diffusion of this technology (Table 1. and Fig. 1.)

The data in the Table 2. reveal that the majority of farmers perceived the cultivation of eucalyptus species required less cost as well as operational cost (78%). When profitability was analyzed, maximum number of farmers (68%) felt that it had given higher profit. Similarly when complexity of growing this species was analyzed, 68% of the farmers felt that it was not difficult to grow. It is very interesting to reveal that 72 % of farmers felt that eucalyptus was not compatible as they felt that the growing of eucalyptus decreases the soil fertility. Also, trailability of the technology was measured and the finding revealed that nearly 92% of the farmers felt that it is trailable on a small scale.

The data in the Table 3. and Fig. 2. indicates that 43.33 per cent of the farmers were aged beyond 35 years. Majority of the farmers were not participating in the social activities and had very low social participation level (76.67%) and belonged to low income group (56.67%). A great majority of the farmers possessed 2.5 to 5 acres of land (83.33%) while 56.67 per cent of the farmers had medium extension participation level. It is very interesting to note 43.33% farmers belonged high age category and 40% of the farmers had high scientific orientation.

The farmers perceived that non-availability of saplings, lack of know-how and marketing the produce are the major constraints in the spreading of Eucalyptus species.
Though the technology possess relative advantageous, compatible, less complex, trialable it took nearly 43 years to reach all the farmers of the selected villages. This points out that the concerned agencies will have study other personal, socio-psychological and cultural characteristics of the farmers in addition to the technological characteristics in order to reduce the diffusion period and hasten the rate of adoption.
