1. piaf piaf Planning-, information- and evaluation - system for field trials Gregor Zink, proPlant GmbH

2. piaf History of development 1995-1997 piaf started as a research project Involved parties: German Federal Office of Plant Varieties (BSA), Advisory services of the Federal States of Germany, Plant breeders and the University of Münster The aim of the project was the development of an evaluation system based on SAS and a relational database Since 1998 In cooperation with the advisory services and the chemical industry in Germany a complete planning-, information and evaluation system has been developed based on the results of the research project Today, piaf supports the whole workflow beginning with the planning phase up to the evaluation of single trial and trial series

3. Support of various trial types and application areas Variety trials Efficacy trials for plant protection products Fertilizer trials et al. Support of various trial designs Arbitrary number of trial factors Evaluation of single trials and trial series depending on the trial design Optimization of data exchange Federal state - Federal state (Germany) Fedaral state - German Federal Office of Plant Varieties (BSA) Trial station – Chemical industry Chemical industry - German Federal Biological Research Centre for Agriculture and Forestry (BBA) Support of the whole workflow depending on the application area Management of large amounts of data piaf Main objective Trial types based on EPPO guidelines

4. Officials of the Federal States of Germany All trial types from the planning up to the evaluation Private trial stations Data entry and report of single trial results (various trial types) Chemical industry Order Management (efficacy trials) In some cases piaf is used as central database for all trials German Federal Office of Plant Varieties (BSA Interface to the federal states of Germany and the plant breeders Planning and data entry system for their own trials German Federal Biological Research Centre for Agriculture and Forestry (BBA) Central database for the validation of efficacy trials Planning and data entry system for their own trials piaf User of piaf

6. piaf information system Query The query module is the basis for further functions like reporting, summaries, data exchange and PIAFStat Query conditions can be defined for every item of a trial; for instance searching active ingredients or plant protection products combined with targets and crops or assessment values is possible.

7. piaf information system Reporting piaf contains a reporting tool which allows advanced users to create new or adapted versions of existing reports, which can be included as menu items for other users All reports and summaries are based on Excel, this gives a user the possibility to use the output for further work Nevertheless, the piaf reporting tool allows the definition of printable Excel–files, which contain format specifications like fonts, colours, frames, page breaks, repeated header et al. All trial data is available in the trial reports

9. piaf information system Summaries Summaries in piaf are not restricted to treatment mean values, an overview about the conducted trials belonging to several crops, targets and years is possible as well as an overview about the conducted assessments of a number of trials which can be used as check function Similar to the reporting tool advanced users can define their own summaries, which can be included as menu items for other users A second summary tool is used more in the context of variety trials and gives a number of additional features like the calculation of relative values
