The yields were as follows, in ardebs per feddan : 



Experiment 3. This experiment was divided into thirty-six 

 plots as follows :

For treatment with the CuS0 4 , the seed was thoroughly moist- 

 ened with the solution, while that treated with the Cyllin was left 

 for three hours in the solution. 



With regard to the effect on the germination, there was no appre- 

 ciable difference between the untreated plots and those treated with 

 CuS0 4 , one-half and two per cent, and Cyllin 1 in 2,000 and 1 in 1,000. 

 But a drop in the germination was evident in the plots which were 

 treated with the stronger solutions, in fact two of the plots, which 

 had been sown with seed treated with Cyllin 1 in 250, had very few 

 plants indeed. 



The following table gives the yield in ardebs per feddan for the 

 grain, and also shows the number of diseased ears which were picked 

 out from the different plots between April 21 and 28 :
