suri'oundiiig a farmei-'s experiment are considered, tlie width whicli will give the most 

 all-round satisfaction will be twice the width of the drill, i.e., a width requiring one 

 round of the drill to plant it. 



The following table gives the dimensions of quarter-acre plots and half-acre plots, with 

 the dift'erent size drills on the market : — 



It is desirable and convenient to jjlant longer plots than is required Ijy the area 

 determined upon. If longer plots be planted, any excess at the ends can be removed 

 before the produce of the jjlots required for comparison is harvested. 



Having decided upon the dimensions of tlie plots, they should l)e marked out liy 

 placing firm stout pegs at the corners. These pegs should l)e numbered as re(iuired. 



For convenience of harvesting, either with a reaper and binder or with a strijiper, it is 

 necessary to leave spaces or divisions between the plots. These divisions sliould Ije at 

 least 6 feet, and are preferaldy 9 feet wide. Where the drill is used, such spaces or 

 divisions can be conveniently made by running the drill empty for one width after 

 planting one plot and before commencing to plant the next plot. 



Before commencing to plant the experiment, see that the machine is in gear, and that 

 the seed and fertiliser will be distributed at and from the boundary of the plot. 



EXPERIMENT No. 1. 



A Trial of Five Varieties of Wheat. 



In this trial five varieties of wheat are to be grown under the same conditions and com- 

 pared with each other. One of the varieties is to be the one which has been chosen and 

 which is being used l)y the experimenter for his main crop The seed of the other four 

 varieties will be supplied by the Department. 



This experiment will require at least five plots. More valuable and reliable results 

 will, however, be obtained if seven plots are used as per Plan 1. Of the three ])lans 

 submitted, tlie experimenter is to choose the one most suitable for his conditions. 



With the exception of the check plots, which will be planted witli the variety used by 

 the experimenter for his main crop, a ilifferent variety is to be planted in each plot. 

 All the varieties are to be planted in the same way, at the same rate, at the same 

 uniform depth, and on the same da}'. 



Plant the varieties in accordance with the arrangement shown on the plan selected. 



The variety will l)e distinguished by the letter A
