This season the mustard plants on the fertilized portions of the plats were practically 

 all healthy, while those on the unfertilized portions were greatly affected by finger- 

 and-toe disease. It is not known whether or not this result was due to the fertilizers 

 applied. The first cutting of mustard in 1902 yielded 6,888 Lbs. of green crop per 



acre, and the corresponding cutting of tares 8,463 ll>s. These yields furnished 27 .5 

 and 60.1 lbs. of nitrogen pet acre, respectively. 



Tests of 2 grass mixtures consisting of grasses and clovers together with certain 

 deep-rooting plants, such as chicory, burnet, and kidney vetch, are described. The 

 rotation consists of pasture 4 or 5 years and roots, cereals, and roots each 1 year, aftei 

 which the land is again seeded to grass in a cereal crop. This year was a first season 

 for the grass crop, and the yields were over 3 tons 7 cwt. for one mixture, and over 

 2 tons is cwt. for the other. 



Experiments on the prevention of potato diseaseon Lansome Field in 1902 showed 

 that where potatoes were sprayed July 24 with a mixture consisting of 20 lbs. of 

 sulphate of copper, 20 lbs. of lime, and 100 gal. of water, there were never more than 

 2 cwt. of diseased tubers per acre as compared with 17 cwt. for the unsprayed crop. 

 Spraying appeared to prolong the period of growth and to increase the starch assimila- 

 tion. In connection with this experiment, manure from bullocks fed linseed cake 

 and decorticated cotton cake was more effective than manure from bullocks fed 

 beans, oats, and wheat. 



Fresh lime at the rate of 2 tons per acre seemed more effective in reducing finger- 

 and-toe disease in turnips than either gas lime, finely ground lime, or lime treated 

 with carbolic acid applied at the same rate. Basic slag at the rate of 10 cwt. per acre 

 was not as effective as the different forms of lime. 



Cooperative field experiments, 1903 (Jour. !></>/, Agr.and Tedk. Instr. Ireland, 

 f i 1904), No. ■!, pp. 469-510). — Similar experiments were made in 1902 (E. S. R., 15, 

 ]i. 664 ). In a variety test Archer Chevalier barley, as in previous years, gave a better 

 average yield than either I roldthorpe or Standwell, but in quality it was inferior to 

 these varieties. Goldthorpe and Standwell mature better than Archer Chevalier in 

 unfavorable ripening weather, but are subject to loss through the dropping off of the 

 heads. 



The results of fertilizer experiments with Archer ( hevalier showed but a nominal 

 profit, and indicated that in general each farm needs its individual fertilizer treat- 

 ment. For soils in a low state of fertility the application used, consisting of 1 cwt. of 

 sulphate of ammonia, 3 cwt. of superphosphate, ami 2 cwt. of kainit, was productive 

 of good results. 



In a second series of tests Archer Chevalier gave a better yield and a higher return 

 than Carton Brewers' Favorite, Carton Invincible. Hallett Pedigree, and Scotch 

 Chevalier. In previous years Hallett Pedigree and Scotch Chevalier were much 

 superior in quality in certain counties. The Garton varieties stood low in money 

 value per acre, but in quality and manner of ripening they ranked above the Cheva- 

 lier varieties. 



A fertilizer tot was made on the same farms with 1 cwt. of sulphate of ammonia 

 and 3 cwt. each of superphosphate and kainit per acre, applied in different combina- 

 tions. Sulphate of ammonia given alone invariably retarded the ripeningand showed 

 a tendency of producing a late second growth, especially during a wet season. Super- 

 phosphate and sulphate of ammonia given together produced a very profitable aver- 

 age increase. The addition of kainit to the mixture had but little effect. The use 

 of superphosphate and kainit had a very marked effect upon the quality of the grain. 



Fertilizer experiments on meadowsare reported and, based on the results obtained, 

 a general application of 1 cwt. of nitrate of soda, 2 cwt. of superphosphate, and 2 

 cwt. of kainit per acre for meadow lands is recommended.
