AN ANALYSIS OF THE PEA TEIALS AT WISLEY, 1911. 

 By Feank E. Durham, A.M.Inst.O.E., F.E.H.S. 

 Data taken from Vol. XXXVII., Part 2, pp. 403-424. 



The following general particulars regarding this trial may be noted : 



The quantity of seed of each stock sown was half a pint. 



On satisfactory germination the plants were thinned out to between 

 3 and 4 inches apart. 



The seed was sown in rows running east to west, the ground 

 sloping gently from south to north. 



The expression " above ground " refers to the appearance of the 

 first leaves. 



The expression " ready to pick " refers to time when the row 

 suppUed a sufficient quantity for household purposes. 



Two errors of printing occurred, and the corrections have been 

 made for purposes of taking the averages. These misprints refer to: 



(a) Stock No. 23, third sowing, the first flower date should be 

 July 10 and not June 10. 



(h) Stock No. 64, first sowing, the first flower date should be 

 May 25 not April 25. 



In the following analysis, all those stocks which either failed in 

 the third sowing or gave unreliable data as to when they were " ready 

 to pick " have been eliminated, in order that the sequence of comparison 

 could be maintained. Further, such stocks which were grown in two 

 or more samples have been accepted as only indic,ative of one stock in 

 the averages. In other words, the 167 stocks are reduced to 155 

 distinct varieties, and of these ninety-two stocks are available for 

 comparison. 



These ninety-two stocks have been subdivided into four classes as 

 follows : 



80-90 day peass represented by 4 stocks 

 91-100 „ „ „ 30 „ 



101-110 „ „ „ 40 „ 



111-120 ,, „ „ 18 ,, including two stocks 



over 120 days. 



Before returning to the analytical examination, it may be well to 

 re-state the dates of sowing : 



1st sowing March 8 



2nd „ April 21 or an interval of 44 days 

 3rd „ May 22 „ „ 31 „ 



The stocks are referred to by their index numbers only; reference 

 may be made to the original report for the names of the varieties. 



In Table I. the ninety-two stocks have been tabulated, sub- 

 divided into the above classification, giving the intervals in days 

 between the four stages of growth as well as the total number of days 

 required for each sowing until the peas were " ready to pick."
