For performing analysis, input the data in the following format. 

{Here we call the feeds as treatments: TRT and yield as YLD. It may, however, be noted that one can retain the same name or can code in any other fashion}.

For ease of understanding, recode the three feeds from 1 to 3 as follows:

Following are the brief description of the steps along with screen shots.
      · Open Data editor: Start® All Programs ® SPSS for Windows® SPSS 15.0/ SPSS13.0/
                   SPSS10.0

      · Enter data in SPSS Data editor. There are two views in SPSS Data Editor. In variable view, one can define the name of variables and variable types string or numeric and data view gives the spreadsheet in which data pertaining to variables may be entered in respective columns.

 · Once the data entry is complete, Choose Analyze from the Menu Bar. Now select 
   Analyze® General linear Model ® Univariate.

 ·  This selection displays the following screen

· Select YLD and send it to the Dependent Variable box; TRT may be selected for Fixed Factor(s) box. After doing these the dialog box should be like this.  

·  Now define model as per design adopted to analyze the data. A Click on the model displays Univariate: Model dialog box. Click on custom then change the Build Terms as Main effects and send TRT(F) to the Model box.
           

 One gets the following screen  

·           Click Continue to return back to the Univariate dialog box, 

·           Now select any one of the postHoc option to select the desired multiple pairwise comparison procedure  from the following screen:  

·           Click Continue to return back to the Univariate dialog box, 

·           Click on OK to get the output.

To answer the questions 1 and 2 one can define the following syntax in the syntax editor after creating the data file.

UNIANOVA

  YLD  BY TRT

  /METHOD = SSTYPE(3)

  /INTERCEPT = INCLUDE

  /POSTHOC = TRT ( LSD )

  /CRITERIA = ALPHA(.05)

  /DESIGN = TRT .
