AN ANALYSIS OF THE PEA TRIALS AT WISLEY, 1913 * 



By Frank R. Durham, A.M. Inst. C.E., F.R.H.S. 



The general arrangements of this second series of trials were the 

 same as those for the year 191 1, the chief difference being that later 

 dates were selected for the three sowings. 



The total number of stocks was 217, representing 188 varieties 

 (29 being duplicates). The results of the sowing of these duplicates 

 have been separately observed, and not, as was the case in 1911, grouped 

 together in one series of figures. The results, therefore, have been 

 included in the calculation of the averages. Out of the 217 stocks, 

 105 are available for averages — that is to say, they gave complete 

 results for the three sowings ; 112 stocks failed to give complete results, 

 or about 52 per cent, of failures, as compared with 45 per cent, in 1911. 

 These 105 stocks included 43 stocks or varieties which were not tried 

 in 1911. There are, however, 38 similar stocks which gave full 

 results, and these have been tabulated and averaged for the sake of 

 comparison. 



The 105 stocks are subdivided into the same classification used in 

 the previous analysis, namely : —

Before deahng with the details of examination of the analysis, 

 it may be well to compare the dates of sowing : —

In Table I. the 105 stocks have been tabulated and subdivided into 

 the above classification, giving the intervals in days between the four 

 stages of growth, as well as the total number of days between sowing 

 and " ready to pick " (p. 68).
