Corn, field experiments tcith fertilizers (pp. 25-37). — A report on experi- 

 ments in 1890 at the station and by three farmers in as many counties 

 of the State. The plan followed was in general that described in Bulle- 

 tin vol. iir, No. 2, of the station (see Experiment Station Record, vol. 

 II, p. 122). The results are stated in tables, and comi)ared with those 

 of 1889. In every case where barnyard manure was used, there was 

 an increase of from 2.9 to 2G.4 bushels in the yield. The results from the 

 use of superphosphate, muriate of potash, and nitrate of soda, sir.gly 

 and in combination, were quite variable, and in general contirmed the 

 tentative conclusions drawn from the previous experiments. Valuing 

 corn at an average of 33^ cents per bushel, the increase in yield due to 

 the use of fertilizers was not sufficient to pay their cost in any of the 

 tests of 1891). 



Corn, summary of experiments (pp. 37, 38). — The following statements 

 are taken from the summary given in the bulletin : 



(1) From the laif^f yellow dent class, only n few are recoimnended for Ohio soil, 

 namely, Bitj Buckeye, Leaminj;, Learning Improved, Mnrdock Yellow Dent, and 

 Woodworth Yellow Dent. From these the Leaming or Learning Improved might bo 

 selected as the most prolific. The Clarago from among the medium dents and the 

 IJutcher corn from the mixed dents, are both good varieties and will mature in an 

 ordinary season. Hriar Crest Beauty, Chester County Mammoth, Golden Beauty, 

 Golden Dent, and Cloud Early Dent are large and productive varieties, but can not 

 be relied upon to mature on Ohio soils. Golden Dent and Golden Beauty are believed 

 to be one and the same variety. • » • 



(2) The results of previous experiments are confirmed by the work of this year, in 

 showing that more and better corn can be raised to the acre where the stalks average 

 12 inches apart than where they are at less or greater distances. The results in 

 "'eneral are as good when the corn is planted in hills as when planted in drills, when 

 the average distances of the grains or stalks are the same. 



(3) The results of a 4 years' comparative test fail to shoi* any marked superiority 

 in the productiveness of seed taken from the butt, middle, or tip of the ear. 



(4) The results of 2 years' experiments are slightly in favor of shaBow culture. 



(.")) The exact stage of maturity at which corn is cut may materially aD'ect its final 

 yield per acre. 



(()) Ked Cob Ensilage, Blount White Prolific, and B. and W. are good varieties 

 for the silo. Early Sanford and sweet fodder corn are not as a rule piofitable in this 

 State for silo purposes. * • •■ 



(7) The results of 2 years' experiments, conducted on the station farm and in vari- 

 ous sections of the State, indicate that in Ohio the use of commercial fertilizers on 

 corn, at present prices of grain and fertilizers, is likely to result in loss more often 

 than in profit.
