I^IELD CROPS. 773 



consisted of tests of 'M varieties and comparisons of (•roi)s on i)lats 

 plcanted at dilferent intes with lister and Avitli planter; ;ind on plats 

 cultivated either deep or shallow and with varying- fre(pieney. 



Tabuhated data and discussions are given for each test. The results 

 are hrietly as follows: The best yields were from medium sized vari- 

 eties which had been grown in the vicinity or in southern Kansas for 

 some years. The 6 plats drilled with the ordinary planter gave a yield 

 14 per cent greater than that of the listed plats; and of the drilled 

 plats, that planted ^larch 28 was best. 



With both medium and small eared varieties thicker planting than 

 usual gave the best results, the largest yields of both corn and stover 

 with the larger variety being from the plat planted with .'> kernels 

 every 24 in. in 3-foot rows; and with the smaller variety from 2 kernels 

 each 1) in. 



The average yield of the 4 plats given shallow cultivation was 18 per 

 cent greater than of the .> plats given deep cultivation. Cultivation of 

 plats 3 times a week gave slightly larger yields than did weekly culti- 

 vation, but the increase was not equal to the extra cost. 



Determinations of moisture in corn grown in these tests and har- 

 vested and sampled at ditterent dates were made. Corn husked from 

 standing stalks averaged 23 per cent, and that from stalks cut August 

 1 and sampled September 12 averaged 12.5 -per cent. When well dried, 

 08 lbs. of ear corn of any of the better varieties gave 56 lbs. of shelled 

 corn. 



The profitable amount of seed per acre for corn, W. H. Jordan 

 {Maine Sta. Bpt. 1895^ pp. 19, 20), — This is in continuation of experi- 

 ments described in the Annual Eeportof the station for 1894 (E. S. II., 

 7, p. 856). In 1895 an acre tract of land received an application of 10 

 two-horse loads of barnyard manure and 750 lbs. of commercial ferti- 

 lizer, and was divided into 4 duplicate series of 3 plats each. In each 

 series plats were planted with kernels 0, 9, and 12 in. apart. The corn 

 was cut for silage and samples analyzed. Tables show the composi- 

 tion of the crop of 1895, and yields of 1894 and 1895. 



"The results so far reached, iudicate thatthe amountof seed may vary greatly with- 

 out materially affecting the yield of dry matter in the mature crop. The average 

 yield jier acre of dry matter for the 2 seasons, with the several rates of seeding, are 

 as follows: Kernels G in. apart, 5,246 ll.s. ; 9 in., 5,390 lbs. ; 12 in., 4,848 lbs. 



"There appears so far to be only a small difference between 6 in. and 9 in. seeding, 

 whereas the yield from the 12 in. was materially smaller l)oth years. 



"It should I)e noted that the corn from the 9 in. and 12 in. seeding was eared more 

 Batisfactorilj' than that from the 6 in. " 



White or yellow varieties of corn, V.. H. Hess {Pennsylvania 

 Sta. Rpf. 181)5, pp. Ill, ii.2).— The results derived from a compilation 

 of analyses of white and yellow varieties of corn are given. The author 

 concludes that the difference does not in any case exceed \ per cent, 

 and that the composition does not vary enough to \w. of any significance.
