344 EXPERIMENT STATION RECORD. 



for oats, the best yields for 5 years in succession were obtained from 

 the spring-plowed land. The average yield was 27.4 bu. per acre, or 

 about 2 bu. more than was obtained from the fall-plowed or unplowed 

 land. 



In experiments carried on for 5 years the best yields were obtained 

 from oats sown the first or second week in March. These plants also 

 grew taller and had larger panicles than those from later seedings. 



Light, common, and heavy oats were used for seed. The common 

 grain was the grain as it came from the thresher. The average yields 

 for 8 years were 27.5, 28.89, and 30.9 bu. per acre, respectively. 



Trials with different methods of seeding were carried on for 7 years. 

 The seed was sown broadcast and with a hoe drill, a shoe drill with 

 press wheels, and a shoe drill without press wheels. The average yields 

 were 26.24, 28.34, 30, and 31.54 bu. per acre, respectively. 



The average results for 7 years from different rates of seeding were 

 as follows : One bushel of seed per acre yielded 24.05 bu. ; li bu., 27.87 

 bu.; 2 bu., 29.12 bu.; 2i bu., 30.86 bu.; 3 bu., 30.43 bu.; 3i bu., 30.43 

 bu.;4bu., 32.79 bu. 



Land subsoiled in the fall of 1895 yielded 52.56 bu. of oats per acre, 

 while unsubsoiled land yielded 53.17 bu. " Subsoiling has almost 

 invariably decreased the yield of wheat, corn, and oats on the college 

 farm." 



Fall-plowed and spring-plowed land was packed with Campbell's 

 subsurface packer previous to seeding. Fall-plowed land packed once 

 yielded at the rate of 29.37 bu., and the plats packed 3 times yielded 

 at the rate of 29.34 bu. per acre. The unpacked fall plowed land 

 yielded 25.49 bu. per acre. Spring-plowed land packed once yielded 

 at the rate of 27.87 bu. per acre, and plats packed 3 times yielded at 

 the rate of 29.37 bu. per acre. Unpacked spring-plowed land yielded 

 22.24 bu. j)er acre. 



Among the varieties tested for 7 years the so-called red varieties, 

 such as Pedigreed Eed Eust Proof, Eed Eust Proof, and Eed Georgia, 

 have given the most satisfactory results in general. 



With the use of " Ceres Pulver " the percentage of smut was reduced 

 from 19.03 to 5.38. 



Potatoes : Tests with fertilizers, M. A. Scovell (Kentucky Sta. 

 Bid. 72, pp. 1-9, pi. 1). — Fertilizer tests were made on tenth-acre plats 

 with nitrate of soda, acid phosphate, and muriate of potash applied 

 singly, in twos, and the 3 substances together. Nitrate of soda and 

 muriate of potash were applied at the rate of 160 lbs. per acre, and 

 acid phosphate at the rate of 140 lbs. These amounts furnished 25.6 

 lbs. of nitrogen, 80 pounds of potash, and 57 lbs. phosphoric acid. 

 Nitrate of soda and acid phosphate applied singly resulted in loss as 

 compared with the check plats which received no fertilizer. The use 

 of potash alone greatly increased the yield. Acid phosphate and 

 muriate of potash applied together resulted in the best yield (109.6 bu.
