422 A.GRIOU LTURAL EXPERIMENT STATION, ItHACA, N. Y. 



Nebraska. — Two experiments; tassels removed by a corn knife; 

 results, decidedly unfavorable. 



Kansas. — A gain in favor of removing tlie tassels. 



Maryland. — Slightly decreased yield. 



Of three experiments at this station, two give an increase in 

 yield of fifty per cent and seventeen per cent, respectively, while 

 the third shows no change in yield. 



It will be noticed that of the total number of experiments, 

 about one-half have received a marked increase in the yield of 

 corn and about one-half report a decrease, but from the experi- 

 ments made in removing the tassels as soon as they could be 

 seen and without injuring the leaves, the lesiilts show, as an 

 average, a marked increase in the yield of grain. 



The varying results of these experiments lend to show that 



there are some conditions not well understood, that have a marktd 



intiuence on the result of this practice, and Ihat it is worthy of 



more extended investigation.

EFFECT OF FERTILIZERS ON TOBACCO. 



In the spring of 1892, four plots were selected to make a test 

 of different kinds of fertilizers on tobacco. This test was made 

 as a preliminary trial to future experiments and intended only as 

 a guide for investigations in testing different kinds and 'lualiti'-s 

 of fertilizers when applied to the tobacco crop. As these results 

 were quite marked, the publication of a brief account of the 

 experiment seemed to be warranted from the data obtained. 



Of the available land for this experiment four adjoining plots 

 of one-fortieth acre each were selected. The soil was a heavy 

 clay loam quite poor in plant food, and not very uniform. Although 

 the plots were only four rods long, the soil varied considerably 

 from one end of the plots to the other. These plots were situated 

 on a western slope; the east or upper ends of each i)lot was more 

 clayey and the west or lower ends more loamy. This variation in 

 the soil was quite uniform throughout all the plots; that is, the 

 soil in one plot varied about as much as it did in another. 



April fifteenth, a load of 2,:i.^).5 jjounds <)f bani manure was 

 spread on plot one. April eighteenth, all plots were plowed.
