EXPERIMENTAL FARMS 



5-5 EDWARD VII., A. 1906 



PLOT EXPERBIEXTS. 



Clover, 0. A. C. Culture. — Adjoining areas of fairly uniform soil, each 33 by 32 

 ^eet, were so-wn with inoculated and untreated seed. The date of sowing was May 9. 

 Owing to the appearance of weeds, the first cutting was raked off and not weighed. 

 The yields of subsequent cuttings were weighed as hay.

Clover, Washington Culture. — These plots were also contiguous, each measuring 

 80 by 12 feet. The date of sowing was April 25. The first cutting was raked off and 

 not we'ghed, owing to weeds.

From the inoculated seed, in both instances, larger yields of hay were obtained. 



Alfalfa. — Owing to insufficient drainage on one of the plots used in the experiment 

 with Washington culture the results were vitiated, and accordingly are not given. 

 With the O.A.C. culture, the plots were 33 by 22 feet, and adjoining; the soil, as far 

 as could be judged, was fairly uniform throughout.

We could not say that inoculation had decreased the yield, the falling oif is most 

 possibly due, to other causes, but the fact remains that a heavier crop of Alfalfa hay 

 was obtained from untreated seed in all three cuttings. 



It is to be hoped that the plants on all these plots will survive the winter, so that 

 the effect of the cultures during the second season of growth may be determined. 



At the close of the season a number of roots, both of Clover and Alfalfa, from all 

 the plots were carefully examined, but no difference in either the size, number or dis- 

 tribution of the nodules was to be observed, indicating that the soil of the experimental 

 farm is well supplied with the nitrogen-fixing bacteria.
