The study aimed at analyzing the extent of existing structural and functional linkages between and among the Research Sub- system (RSS), the Extension Sub-system (ESS), the Client Sub- system (CSS) and the Input Sub- system (ISS) in the transfer of technology (TOT) of improved rice varieties released by the Kerala Agricultural University (KAU). The study was conducted in the Alleppey, Ernakulam, Trichur and Palghat districts of Kerala. Respondents of the study consisted of 52 researchers, 134 extension personnel, 110 farmers and 32 representatives from the input agencies.
To delineate the structural linkages between and among the four sub- systems involved in the TOT process, detailed analysis of the existing formal mechanics of linkage were analysed.
Linkage activities that could be performed by each sub- system were identified and relevancy rated for measuring the extent of performance and perception of importance of these linkage activities by the respondents. A linkage index was developed to measure the perception of importance of linkage activities by the respondents.
Data from the RSS, ESS, and ISS were collected using separate pre-tested structured questionnaires. Data from the CSS were collected using a pre- tested structured interview schedule.
In structural linkage, it was found that there were appreciable linkage forums for the RSS and the ESS. But there was lack of organized linkage forums for the CSS and the ISS. Representation for the ESS in the linkage forums of the RSS was found to be restricted to higher officials. There was no representation for the ISS in the important linkage forums of the RSS. The regularity and periodicity of convening of the package of practices workshops, Extension Advisory Committee (EAC) and State Level Technical Committee (SLTC) were also found not being strictly adhered to.
In functional linkages, the extent of linkage of the ESS with CSS and the ESS with the ISS were significantly better and reciprocal. Though the RSS viewed its linkage with the ESS and the CSS as good, the ESS and the CSS did not subscribe to this view. Similarly, the ISS viewed that its linkage with the RSS and the CSS was good but the RSS and the CSS did not corroborate this. Based on these results the hypotheses set for the study were either rejected or accepted.
In order to segregate the factors associated with the functional linkages between and among the four sub- systems in the TOT of improved rice varieties, principal- factor analysis was done and the factors were extracted and labeled appropriately.
The perception about the importance of linkage activities of the ESS with the CSS and the ISS was significantly better and reciprocal. But the perception about the importance of linkage activities of the RSS with the ISS, the ESS with the RSS and the CSS with the RSS and the ISS were significantly poor and hence the hypotheses set for the study were rejected.
Lack of infra- structural facilities for research followed by insufficient staff strength and lack of facilities to multiply seeds were the most- important constraints in evolving and spreading the improved rice varieties as perceived by the RSS.
Susceptibility to pests and diseases followed by the need for heavy dose of fertilizers and pesticides and poor cooking quality were the most important constraints in spreading and adopting the improved rice varieties as perceived by the ESS, the CSS and the ISS.
Based on the results of the study, certain important implications have been spelt out.
