As with the Complex, Diverse and Risk- prone (CDR) rice systems of many Asian countries, the Kerala state of peninsular India suffers from the fast depleting paddies and the ' high cost- low remuneration syndrome'. Crucial rice technologies have been blamed by stakeholders for the insensitivity to micro farming situations A multidisciplinary stakeholder Participatory Action Research (PAR) of emancipatory type and collaborative mode was done for three years (2001-2004) on identification and prioritization of constraints to profitable rice production to explore the available cost-reducing and productivity increasing technological options. The project focussed on screening of technological modules through farmer participatory field assessment and arrived at locally adaptable and remunerative technology packages. The project also developed and standardised an extrapolatable stakeholder participatory assessment model and protocol. The programme had a blend of extension approaches, research designs and tools like "ex-post facto", benchmark appraisal through Participatory Learning and Action (PLA), exploratory, diagnostic, evaluative, field experiments and analytical studies. The PAR was done in two rice ecosystems (irrigated and rainfe:l) of the midland, laterite belt of Kerala state, India. Fourteen technology modules were fitted into the PAR, under .. , each of the three treatments, viz., farmers' practice, recommended packages of the formal research system and location specific I technology components" jointly decided by the research team extensionists and farmers. Each technology component was subjected to five types of analysis viz., agronomic, statistical, economic, farmers perceptions and reactions, post-trial follow up analysis of adoption in the succeeding cropping seasons. The participatory interventions significantly influenced the level of technical knowledge and extent of adoption of adaptable technology modules, typifying the cognitive impact of an emancipating action research. The short duration red rice varieties "Kanchana" (Ptb 50) and "Kairali" (Ptb 49) proved to be the best first crop and second crop varieties respectively, to replace the ruling cultivars. The technology modules recommended by the formal research system viz., seed treatment with fungicides for the first crop season and Pseudomonas fluorescence for the second crop season were adaptable technologies. The PAR came out with an efficient planting density and crop geometry package (line transplanting; 15 x 10 cm; 67 . , hills/m'; 2-3 seedlings/hill) to replace the conventional planting system. The existing formal recommendations including IPM and INM practices could enhance and combat weeds, pest and diseases thereby enhancing crop yield. Harvesting with self- propelled reaper and threshing with mechanised thresher were cost effective, drudgery alleviating and time saving. The net result of the action research was a set of adaptable technological package for remunerative rice production in the CDR rice production systems. Cognitive and behavioural impact on the participants; and the standard methodology and protocol for participatory technology validation for rice in particular, and for any farm enterprise in general, with extrapolative effect.
