Fifteen salt tolerant CIP (International Potato Centre) Potato genotypes along with BARI (Bangladesh Agricultural Research Institute) Alu 7 (Diamant) and one local variety viz., Dohazari Sada were evaluated at Bashkhali, Chittagong during 2011-12 to screen the suitable genotypes for cultivation in saline areas of Bangladesh. Diamant and Dohazari Sada and all of the CIP genotypes were found to grow well up to 60 DAP (Days After Planting) at saline areas having healthy plants and no senescence was noticed but after that 61-100% plants died due to high level of soil salinity (6.41dS/m) depending on genotypes. Genotype CIP 112 gave the highest yield (21.07 t/ha) and CIP 102 was comparatively less affected by soil salinity than the other genotypes. However, all the salt tolerant CIP genotypes were found to be promising in the saline soil. DOI: http://dx.doi.org/10.3329/agric.v11i1.15249 The Agriculturists 2013; 11(1) 95-102

SUMMARYResearch institutes in Africa have had limited success in producing new technologies appropriate to the needs of small farmers because of an inadequate understanding of small farmers' goals and resource limitations and over-reliance on the transfer of technologies from other regions. Farming systems research (FSR) is an effective way of improving the focus of scientists on the problems farmers face. Vertically segmented thematic research programmes make institutionalization of FSR difficult within multi-commodity research centres, particularly the International Agricultural Research Centres. The Farming Systems Research Group has proved effective at overcoming such difficulties at the International Institute of Tropical Agriculture. Its organization, operation and effects on the performance of the research programmes are described.

SUMMARYIn recent years many economists have been posted to agricultural research stations in Africa but their roles and methodologies have not been clearly defined. Maize research in Nigeria has an exceptionally good structure, good facilities and highly trained manpower, yet the innovations recommended to farmers are not entirely satisfactory. Deficiencies are the result of inadequate attention to the way innovations fit into the farm-household system, identification of farmer's objectives, the uses made of maize and problems of resource shortage. Pilot studies demonstrated how these deficiencies may be rectified by an economist, and suggest changed production recommendations and research priorities.

<strong>Indonesian</strong><br />The majority of Indonesian farmers, especially farmers in Java, are small farmers. The number of farmers land holdings of less than 0.5 hectare totals 53.9 percent, those with 0.5 - 0.99 hectare are 22.1 percent, while those with 1 - 1.99 hectare are only 15.9 percent. However, these small farmers are main contributors to food production of the country. This implies that efforts to strengthen agribusiness system at local level will involve 90 percent of small farmers in Java with land holdings of less than 1.0 hectare, and 76 percent of total Indonesian farmers with the same level of land holdings. In this globalization era, there is a need of policy which is supportive to the appropriate technology for small farmers that enables them to manage their resources efficiently based on comparative advantage considerations. In this respect, agro ecosystem diversity and regional development stage in the country, availability and quality of natural and human resources, and local socio economic and cultural condition should be considered in technology generation and development. Several research results reported that the size of the land holding was one of the determinant factors in farmer's decision makin to adopt technology. The difference in the size of land holding, the farmer's productivity, and the availablity of supporting factors boosting agribusiness and agroindustry, indicates a different need of policy in technology development. Small farmers in Java need intensive land utilization technology, even non-land based techniques, and non-labor displacement technology. Thus, generating technology which is suitable for small farmers should be the main priority in agricultural research and development in Indonesia, at least in the coming few periods of the Five Year Development Plan (PELITA).

SUMMARYFarmer participation in agricultural research can improve the efficiency and impact of the research. This functional component of participatory research includes the identification of traits that guide crop breeders' work. Participatory research can also lead to farmer empowerment, although when carried out by research organizations, direct empowerment is often limited to relatively few farmers. Farmer empowerment is, therefore, best carried out by development organizations whose longer-term interaction with farmers is likely to ensure that greater numbers of farmers benefit. Hence, research organizations ought to focus on the functional components of participatory research along with the empowerment of intermediate/partner organizations rather than the direct empowerment of large numbers of farmers.

SummarySurveys and on-farm trials are frequently used to facilitate farmer participation in agricultural research. This paper reports on a less common method-farmer involvement in on-station trials. Thirty-nine farmers were invited to multipurpose-tree screening trials in Burundi. Three different methods were used to determine which species the farmers wanted to test on their own farms. Private interviews and voting by a show of hands in plenary sessions gave very similar results whereas focus group interviews produced different and contradictory results. Researchers also learned what criteria farmers used to evaluate trees and the reasons for their choices. A supplementary survey of farmers’ preferences for trees grown on their own farms confirmed the findings and more clearly defined their criteria. In this survey, farmers used a local board game, Bao, to rate tree species across criteria they considered important. Overall, the visit to the trials and follow-up survey proved to be a useful and cost-effective method for getting farmer input and applying it in the screening process.La participación de los agricultores en la selección de especies de árboles

The study was undertaken to identify genotypic diversity at molecular level of potato for varietal improvement program at the Advanced Plant Breeding Laboratory, Department of Genetics and Plant Breeding, Bongobondhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh. Eight cultivars of potato viz. Lalpakri, Sindurkouta, Indurkani, Ausha, Patnai, Sadaguti, Shilbilati, Challisha were collected from Bangladesh Agricultural Research Institute (BARI), for studying genotyping divergence. Genomic DNA was extracted from young leaves of the cultivars and PCR reaction was performed. The PCR amplified DNA profile was visualized on agarose gel, staining with ethidium bromide. Three RAPD primers named OPA 01, OPA 03 and OPD 18 were used to evaluate the genetic diversity of potato varieties. All the primers were polymorphic and the primers produced the highest number of alleles. The genetic diversity value in Lalpakri with all cultivars except Sadaguti was found to have the highest genetic distance (1.0). The amount of genetic diversity within potato germplasm is quite distinct as revealed by the genetic similarity coefficients. The results indicate that, high level of genetic distance exists among the cultivars. The Primers OPA 01, OPA 03 and OPD 18 showed the highest level of genetic diversity and PIC value while the Lalpakri and Sadaguti cultivars had the highest genetic distance among other cultivars which could be used for further potato breeding program.
