CIMMYT International Maize Trials are sent to cooperators with unique, paper field books for each trial set (or occurrence). Today, many cooperators also prefer to receive field books in electronic formats. This web page enables recipients of IMTN (International Maize Testing Network) to download these unique recipient-specific field books in Excel™ format of Microsoft Office

 

Please do not change the unique file name(s) of download field books if you wish to return data to IMTN using these electronic files. Data should be sent to Efren Rodríguez (e.rodriguez@cgiar.org), or mailed to:

Efren Rodríguez
Seed Distribution Unit
CIMMYT, Int.
Apdo. Postal 6-641
06600 Mexico, D.F.

Several columns in the downloaded field book worksheets are "data protected" to prevent data change. This protection is essential if the files will be used to return to CIMMYT cooperator-collected phenotypic data. If you wish to extract data from these protected columns for manipulation in a spreadsheet, or import into a separate database, use the Edit-Copy-Paste routine in Excel.

Trials are sent using uniquely randomized for all sets (or occurrences). It is therefore crucial that sets of seed and the accompanying fieldbooks are not interchanged, because each set has a specific randomization layout and, therefore, a specific fieldbook.

Each individual set of seed for a trial is given an "occurrence" or set number. Occurrence number refers to the number used to identify the seed set assigned or distributed to each cooperator and links to each specific randomization used. Thus if a cooperator sows more than one set at the same location, these sets will have the same location code, but a different occurrence number. Assure that the occurrence on the fieldbook matches the number on the seed envelopes. In case of a lost fieldbook, IMTN will generate a new one (on paper and electronic form) giving the same set or occurrence number that appears on the nursery seed packets.
