FIELD CROPS. 413 



Field experiments -with -wheat, W. C. Latta {Indiana Sta. Bui. 

 51, xjp. 59-77). 



Synopsis. — The experiments are classed uuder the followiug heads: (1) Test of 

 varieties, (2) quautity of seed per acre, (3) early and late sowing, (4) rotation 

 vs. coutiunons grain crop])ing, (5) earlj' and late harvesting, (6) experiments 

 Avith commercial fertilizers and manure, and (7) cooj>erative experiments with 

 varieties. The results in 1894 differed in most instances from the average of 

 preceding years. The largest yields were made by the variety Rudy ; by sowing 

 6 pecks of seed; by sowing October 4 ; and by harvesting late. Stalile manure 

 in all cases yielded a profit. Commercial fertilizers ga\e a proiit in all cases 

 when used on wheat grown in rotation, but failed to give a net profit when used 

 on Avheat grown continuously on the same plats. 



These experiments, conducted in 1S1)4, are in continuation of those 

 recorded in Bulletin 45 of the station (E. S. R., 5, p. 185). 



Test of varieties (pp. 59-03). — Tabuhited data and descriptive notes 

 are given for 37 varieties of wiieat tested in 1894, and the average 

 yields of varieties tested for 2 to 11 years. In 1894 the largest yield, 

 45.75 bu. per acre, was made by Rudy. Other varieties yielding more 

 than 40 bu. per acre were Fulcaster, Harvest Queen, Jones Winter 

 Fife, Wyandotte, American Bronze, Reliable Minnesota, Early Genesee 

 Giant, and Brown Bearded Velvet Chaff, By comparing the yields of 

 varieties grown at the station 11 years without change of seed, with 

 varieties brought to the station in recent years, the writer finds evi- 

 dence that varieties of wheat do not " run out" when selection of seed 

 and careful culture are practiced. 



Quantity of seed per acre (p. 04). — In 1894 wheat at the rate of 2 to 

 10 pecks per acre was sown. The largest yield resulted from G pecks 

 of seed. Taking the averages for 9 years every increase in the quan- 

 tity of seed up to 8 pecks was followed by an increase in the resulting 

 crop. 



Early and late so}cin(/ (pp. (34, 05). — In 1894 seed sown October 4 gave 

 a larger yield than earlier or later sowing. In. former years earlier 

 sowing had given better results than late sowing. 



Rotation vs. continuous grain cropping (pp. 05, Oi)), — In 1894 the yield 

 of wheat on the plats where the rotation of gram aiul grass was prac- 

 ticed was 9,93 bu. greater than on the i)lats on wliich grain was grown 

 continuously. This increase was greater m 18. )4 than the average 

 increase of the preceding 7 years. 



Early vs. late harvesting (pp. 66, ()7). — In 1894 the first cutting was 

 made June 19, at which time most of the wheat was in the milk stage. 

 Wlien tlie liarvestiug was very early the yield was 25.0 bu., early 30.5, 

 medium 34.3, late 35.8, very late 33.5. The wheat ripened in 1894 

 more satisfactorily thaw m preceding years. " It would appear, there- 

 fore, from the results obtained this year, that the harvest should begin 

 when the wheat is fully in the dough, and be completed by the time the 

 wheat IS fully ripe." 



Experiments with commercial fertilizers and manure (pp. 07-71). — On 

 wheat alternating with corn, clover being grown as an intercrop and
