Experiments with oats, J. N. Harper and A. M. Peter {Kentucky Sta. Bui. 99, 

 pp. 65-78). — The results of a test with 27 varieties of oats in 1901 are given in a tal)le. 

 The yields of grain and straw are reported and the color of the grain, character of 

 the straw, and date of ripening are given. The yields of grain and straw for 4 suc- 

 cessive vears and the weight per measured bushel for 3 successive years are also 

 shf)wn for tlie different varieties. In 1901 the yields of the varieties ranged from 

 29.4 to "I l)u. of grain per acre, the leading varieties being White Russian, Im2:)roved 

 Welcome, Negro Wonder, White Belgian, and New iVmerican, in the order given. 

 The average weight per measured bushel for 8 years was 32.5, 31.1, 30.8, and 30.3 lbs. 

 for Pringle Progress, Probsteir, Hopetown, and Imported ATelcome, respectively. 

 All other varieties gave an average weight of less than 30 lbs. per bushel. 



The results of a fertilizer test with 160 lbs. per acre of nitrate of soda and muriate 

 of potash ajiplied separately showed a material increase in yield. 



Analyses of the different varieties made to determine their relative value for feed- 

 ing are tabulated. The average yield of protein was 293 lbs. per acre and the aver- 

 age percentage 6.77. Basing the selection on the production, varieties yielding 300 

 lbs. or more of j^rotein per acre and having a protein content of over 7 per cent in the 

 dry matter are the l)est for feeding purposes. Analyses of samples of all the varieties 

 cut on July 5, B, 7, and <S indicate that the crops harvested on July 5 would have 

 been slightly richer in protein, but would have given a smaller total yield. In gen- 

 eral, the percentage of protein in the dry matter decreased and the quantity of dry 

 matter increased as the plants reached maturity. The difference in comjiosition of 

 young and ripe oat plants is shown by analyses of samples taken June 16 and July 19. 



Directions for the treatment of seed oats against smut are given and the meteoro- 

 logical conditions for 1898-1901, inclusive, are summarized in tables. 



Fertilizers for oats, L. Grandeau {Jour. Agr. Prat., n. ser., S {1902), No. 6, pp. 

 177, 178). — This article discusses the use of fertilizers for oats on poor soils. Several 

 fertilizer apiilications to suit various conditions are recommended. 



Plant breeding-, :\I. Fisher ( Fiihling's Lambv. Ztg., 51 {1902), No. 2, pp. 411-415). — 

 The results of experiments in breeding winter oats are reviewed. 



Variety and fertilizer tests with, potatoes, W. J. Green and C. W. Waid 

 {Ohio fStd. liiil. l.->3, pp. 7 1-87). — Similar work has been previously reported (p]. S. R., 

 11, p. 42). The yields of 55 varieties tested in 1901, together with the average yields 

 of varieties grown for 3 and 5 years, are tabulated. Each variety tested in 1901 is 

 described. The following varieties, in the order named, were most productive in 

 1901: Northern Beauty, Quick Crop, Maule Early Thoroughbred, Early Norwood, 

 Early Fortune, Pingree, Roberts, Early Rose, and Pat Choice. Among the varieties 

 tested for 3 years, Vigorosa, Maule Early Thoroughbred, Early Rose, Whiton White 

 Mammoth, livingston. Sir Walter Raleigh, Sir William, Uncle Sam, Pat Choice, and 

 Pingree produced the best yields, while of tho.'-e grown for 5 years. Enormous, Liv- 

 ingston, Early Trumbull, Uncle Sam, Sir W^illiam, Sir AValter Raleigh, Bovee, Maule 

 Early Tlioroughbred, Suffolk Beauty, and Carman No. 3 were the leading ones in 

 point of production. Early Trumbull, Early Thoroughbred, Bovee, Early Harvest, 

 and Early Ohio are recommended as early market varieties, and Livingston, Whiton 

 White Mammoth, Enormous, Sir Walter Raleigh, and Carman No. 3 as late market 

 varieties. Early Trumbull, Early Harvest, Livingston, Pat Choice, and Uncle Sam 

 are considered especially adapted f(jr home use. 



The results of the fertilizer test show that superphosphate alone was much more 

 profitable than either nitrate of soda or muriate of potash used singly. The most 

 profitable apjilication in this test consisted of 160 lbs. superphosphate and 80 lbs. 

 nitrate of soda. All the aj^plications tested proved profitable, with the exception of
