1906.] Inoculation of Leguminous Plants. 653 



confirmed by the weights of the harvested peas showed no 

 beneficial results to have accrued from the inoculation. 



Chelmsford. — American inoculating material used in field 

 trials on beans. No beneficial results were obtained with the 

 inoculated plots over the uninoculated, as shown by observation 

 and yield of seed. 



In experiments with French beans, of plots -465 of an acre 

 each, the following results were obtained : — 



Bush. Pt. 



Dressed beans, per acre ... ... ... ... ... 26 2 



Undressed beans ... ... ... ... ... ... 26 if 



Edinburgh. — (a) Garden plots. Two favourable reports and 

 many negative with Moore's culture. 



Glasgow. — Experiments with Moore's and Hiltner's cultures 

 on some twelve farms. 



Moore's cultures for lucerne on one farm in Renfrewshire 

 showed no difference between inoculated and uninoculated plots. 

 In two experiments with red clover, one in Renfrewshire and one 

 in Lanarkshire, the results were entirely negative with Moore's 

 culture. 



Dr. Hiltner's culture applied to a lucerne crop on the Central 

 Experiment Station, near Kilmarnock, which had been sown in 

 the previous year, produced a very striking and remarkable 

 effect on the crop there. 



The table on page 655 shows the results obtained with beans 

 inoculated with Moore's culture on eight farms. Comparing the 

 untreated plots, No. 1 column, with the inoculated plots, No. 2 

 column, manured in the same way, an increase is seen in five out 

 of the eight plots ; in the case of Woodilee, it amounts to a gain 

 in grain of 30 per cent, on the similarly manured uninoculated 

 plot. The 1 cwt. of nitrate does not appear to have been able to 

 serve the plant nearly so well, producing an actual falling off in 

 the yield in this case. 



Kingston. — (a) Five experiments were made in garden plots 

 with peas and three with beans, part of the rows being dressed 

 with Hiltner's cultures and part with Moore's. In one case only 

 the peas inoculated with Hiltner's culture looked better during 

 the early stages of growth than the undressed peas. In all the 

 other cases the dressing was without visible effect. 



(J?) Experiment in accordance with actual agricultural practice.
