corn (1)1). 110-121). — Tbese experiments were made to observe the efifect 

 of sonie of the coiiniion forms of commercial fertilizers, hog tankage and 

 stable manure, on the yield of coru. 



The stable manure was a mixture of horse and cattle manure com- 

 bined with the usual litter. In both experiuients it was applied before 

 the land was plowed. The commercial fertilizers used in Experiment 

 No. 11 were muriate of potash, dissolved bone-black, sulphate of ammonia 

 and hog tankage separately, and a combination of muriate of potash 

 and hog tankage. In Experiment No. 24, besides those already men- 

 tioned, cattle tankage, bone meal, glue-factory super[)hosphate and 

 nitrate of soda were used. In Experiment No. 11 the fertilizers were 

 sown broadcast on the plowed land. 



No appreciable increase of yield was secured by the commercial fer- 

 tilizers on this land this season, and the increase produced by the stable 

 manure, used in Experiment No. 11, was not sufficient to pay for its use 

 unless the surplus fertility left in the soil gives a more marked increase 

 next year. 



General conclusions and suggestions (pp. 121-127). — These, which fill 

 six pages, ''are suggested in part by the experiments reported in this 

 bulletin and in part by those tried in previous years, and by experience 

 in ordinary field culture of corn." They discuss varieties, improvement 

 of varieties, soil preparation and fertilization, planting, cultivation, and 

 harvesting. They do not easily admit of condensation, and are there- 

 fore reserved for the Annual Digest of the work of the stations.

Experiment No. 49. — Sweet corn, testing varieties. — The classification 

 adopted for the forty-seven varieties of sweet coru tested may be tabu- 

 lated as follows : 



Varieties. 



Time of reaching edible matur- 

 ity after plantiag. 



Color.

Detailed descriptions of the varieties fill eight closely printed pages 

 of the bulletin in type. The results of the experiments are recorded in a 

 table, showing number of plat, name of variety, date of first and full 

 bloom, and when first ears were fit for use, days from planting to edible 

 maturity, yield, weight of the selected ears, and per cent of full stand.
