Station Eecord, Vol. T, p. 2S7). As before, the topics are (1) thick and 

 thin seeding; (2) early and late seeding ; (.3) seeding at different depths 

 and by different methods. With two exceptions Velvet Chaff (Peu- 

 quite's) wheat was used in all of tlie experiments rei)orted. 



Thiclc and thin seeding. — This experiment has been repeated during 

 nine seasons. In previous years the land used for the experiments has 

 been "second bottom and light clay loam, with gravel subsoil, " but this 

 year "first bottom or low land was used. " An attempt was made to 

 duplicate the experiments with Velvet Chaff" wheat by using a variety 

 named Dietz on other plats, but these were injured by freezing and ex- 

 cessive moisture. In other years the rates of seeding have been from 

 2 to 9 i)ecks per acre ; this year a 10 peck rate was added. In 1890 the 

 results varied but little. The 5-peck rate gave a slightly higher yield 

 than any of the others, but this was closely followed by the 7, 4, and 6- 

 peck rates. For the nine years the 7-peck rate gives the highest aver- 

 age yield, but is closely followed by the 5 and G-peck rates. 



Early and late seeding. — A table gives the dates of seeding from Au- 

 gust 22 to !N"ovemberl, yield per acre of grain and straw, and pounds 

 of straw per 100 pounds of grain for eleven plats used in 1890. The 

 best results this year were obtained from seeding between October 4 

 and November 1. In another table the yields of grain per acre in simi- 

 lar experiments during seven seasons are compared. 



After seven years' trial we have found that, with a single slight exception, the 

 highest yields have been produced from seeding daring the last week in September 

 and the first week in October. 



For 1890 the product from the land seeded November 1 was almost as high as 

 where the seeding was a month earlier. This was probably due to the unusually 

 open winter of 1889-90. 



Methods of culture and different depths of seeding. — The results at- 

 tained by various methods of seeding, Lois VVeedon culture, mulchings 

 and different depths (^ to 4 inches) of planting the seeds are given 

 in one table for 1890 and in another for five seasons. The variety of 

 wheat used in 1890 was Martin's Amber. Better yields have been ob- 

 tained from seeding from 1^ to 2 inches deep than from shallower or 

 deeper planting. "Five years' experiments with the roller or wheel 

 following in the track of each drill hoe indicate that the practice may 

 be a good one ; at least it is worthy of a more thorough test."

All the tests of varieties of wheat at this station from 1882 to 1889 

 were conducted on the " south field." For the trial of 1890 a level field 

 of alluvial bottom-land, with quite uniform soil, which had been in clo- 

 ver three years, was thoroughly prepared by plowing, rolling, and har- 

 rowing, and was divided into tenth-acre plats. A diagram of the plats
