definitely, their growth and further trials seem warranted in those sections 

 where corn is too uncertain. 



Soy Bean Inoculation. — Four different commercial cultures were used to 

 inoculate the various sections of a plot of soy beans. All the inoculated 

 sections could be detected by the eye on account of the greener color of the 

 foliage. All of the inoculated sections also showed an abundance of nodules 

 on the roots, while the uninoculated showed few, or none. From this and other 

 previous tests it seems quite evident that where soy beans are grown for the 

 first time on a given piece of ground inoculation is strikingly beneficial. 



Early Planting of Ensilage Corn. — It has been contended for several years 

 by the Bureau of Plant Industry that larger yields and a better quality of 

 silage could be obtained in the more northern latitudes of corn culture by plant- 

 ing the later maturing varieties several weeks earlier than the usual planting 

 season. In order to test this theory two late varieties of corn (a dent, U. S. 

 119, and a flint, U. S. 193) were furnished by the Bureau. A high, well-drained 

 piece of stony loam soil (the Heater lot) was selected for the test. Two rows 

 of each variety were planted in 1920 at four different dates, as follows: April 

 27, May 7, May 17, and May 27. The plantings were made heavy and later 

 thinned to an average of one stalk per foot. 



The first planting required 18 days to come up, the second 14 days. The 

 second and third plantings were soon as tall as the first. On August 18 the 

 tassels began to appear, and no difference in the first three plantings could be 

 noted as to their frequency. No tassels appeared on the fourth planting until 

 August 20. 



All the plots were cut October 5, and several interested parties were asked to 

 pick out the plantings in order. The last planting was fairly obvious, because 

 the ears were not quite as hard and mature as the others. No differences, 

 however, could be noted in the stage of maturity of the three earlier plantings. 



The season was an unusual one, in that there were no frosts in the spring 

 after the first planting was up and none in the fall until after the corn was cut. 

 On the basis of this one season's results one cannot say that any advantage 

 was gained by the unusual early plantings. It is hoped that the test may be 

 repeated for further observations on the question at issue. 



Variety Tests of Winter Wheat and Rye. — In the winter wheat tests on one- 

 sixth acre plots eight varieties were tested. These were seeded October 4 and 

 harvested July 18. The yields of grain and straw per acre were as follows:
