Influence of variety and of rate of seeding on the yield 

 OF SILAGE CORN, H. P. Armsky, Pii. D. — Tliis is a report of au experi- 

 ment to determine tlie iiiliuence of variety and rate of seeding on the 

 total yield, composition, and digestibility of green fodder. The general 

 plan was, using the same fertilizers (barn-yard manure and dissolved 

 South Carolina rocic), to i)lant a variety of dent corn (unnamed) and a 

 larger variety (Breck's Boston Market Ensihige) each on four (about 

 one twentieth acre) plats, in rows 3J feet apart, and at the rate of one 

 kernel every 3i inclies and of one every 14 inches in the row ; and to 

 determine the rate of digestibility of the corn for each variety and each 

 rate of seeding by feeding trials with sheep. 



The method of planting, rate of seeding, manuring, cultivation, and 

 harvesting are described and the yield, comi)osition, and rate of diges- 

 tibihty of tiie green crop are tabulated for each variety and each rate 

 of seeding. The results, as calcuhitedby the author, show that in this 

 single experiment there was a larger yield of dry matter and that this 

 had a somewhat higher rate of digestibility where the seeding was 

 thicker and where the larger variety of corn was used. " The thick- 

 seeded corn reached nearly the same stage of maturity as the thin- 

 seeded." 



As mentioned in the bulletin, however, there were several things 

 other than variety and rate of seeding which maj^ have considerably 

 inHueuced the results and which make them merely suggestive. It is 

 hoped to continue the experiments the coming season.

Forest-trees, fruits, and vegetables, C. A. Keffer, M. H. 

 (pp. 123-149). — The importance of tree planting is urged, methods of 

 grove, street, and lawn planting are discussed, and the advantages of 

 certain varieties of trees for groves, streets, or lawns are set forth. For 

 grove planting the cotton-wood [ropulus monili/ern), white willow, box- 

 elder [Ne{jun(lo aceroides), and soft (silver) maple {Acer dasycarpuni) are 

 recommended as rapid-growing varieties, and green ash {Fraximis 

 viridis), white elm {Ultnus amerieana), black wild chervy {Fnmns sero- 

 tina), hackberry (C'e^^js occidentalu)^ black walnut [Juglans nigra), butter- 

 nut {Juglans cinerea), burr oak {Quercus macrocarpa), and black oak 

 {Quereus nigra) as slow-growing varieties. Some varieties of Kussiau 

 poi)lars and willows are promising, and among evergreens the Scotch 

 pine, red cedar, and white spruce may be grown throughout the State. 



Suggestions are made regarding the varieties of fruits and vegetables 

 most likely to succeed in South Dakota. The experiments with orchard 

 fruits at the station have not been in progress long enough to give 

 results of value.
