  • Field hulling of high-moisture paddy followed by brown rice drying offers many advantages over the present paddy harvesting and drying offers many advantages over the present paddy harvesting and drying system. We did a preliminary study of the parameters for efficient hulling of high-moisture paddy using the IRRI Centrifugal Huller and two India rice varieties. Hulling capacity , hulling efficiency , brown rice recovery and percent whole bown rice were generally best at the impeller peripheral speed of 44m/s. A second pass through the huller increased hulling capacity , brown rice revery and hulling efficiency, but reduced percent whole brown rice. To solve this , we recommed separation of paddy after hulling and aspiration such that only unhulled and partially -hulled grains will be fed back to the huller. Paddy at even 23% m.c. could be effectively hulled by the impeller-type huller , but the results were generally better at 14 to 17% m.c. Only in percent whole brown rice did the 17 to 23% m.c. range performed better than that of 14% m.c. Difference invarietal response to hulling was observed.

  • The purpose of this paper is to review research evolution and achievements, major activities, research manpower, and difficulties for social scientists, using IRRI's internal web site and Social Sciences Division's research literatures. The major findings are as follows: 1) Social research started with the establishment of Agricultural Economics Division (AED) in 1966, and it was developed into the Social Sciences Division (SSD) in 1990; 2) Their research has been geared towards developing technological and policy interventions that improve food security and raise the well-being of rice farmers through sustainable increase in the productivity of a rice-based production system; 3) Major activities of social sciences research for about four decades can be classified into the identification of technology needs, technology impact assessment, policy analysis, research prioritization, and capacity building for social science research in NARS (National Agricultural Research Systems). They have become increasingly important in alleviating the poverty of the rice growing and consuming population; 4) Social researchers at IRRI include economists, anthropologists, gender specialists, geographic information specialists, and rural sociologists; 5) Finally, this paper discusses the difficulties faced by social researchers.

  • Capacity building for bioinformatics could be achieved with the systematic training of research staff and higher degree students in the current best practices for analysis of data from 'omic-type experiments. It is anticipated that the KOICA-University of the Philippines Los Baños - International Rice Research Insitute Agricultural Genomics Research Center activities will focus on the use of next generation sequencing technology for genome sequencing and annotation, genome variant discovery for use in GWAS and QTL mapping, and transcriptome analysis of organisms important to agriculture and food security. Such activities require that researchers have high levels of knowledge and skills in bioinformatics in order to gain insights from the results of the experiments performed. In this talk the bioinformatic tools/solutions and online training materials already available will be presented, as well the upcoming resources under development in support of the project.
