FIELD CROPS. 631 



Notes on clover, J. D. Towar {Michigan Sta. Bui. ISl, 2'J'- ^'^^i 

 165). — The great difficulty in .securing a good catch of clover when 

 seeded with wheat, as was fornierh^ the practice in Michigan, led to 

 experiments in seeding this crop alone on well prepared ground. Two 

 eighth-acre plats -i rods apart were used in the test. On 1 plat clover 

 was seeded with wheat; on the other the ground was well prepared 

 and the clover seeded alone. Both plats were seeded the same day. 

 The clover seeded with the wheat was an entire failure, though the 

 wheat 3'ielded at the rate of 42 bu. per acre, while on the plat seeded 

 to clover alone a good stand was secured, and a vield of 4:.U67 lbs. of 

 hay was obtained as a first crop. 



Experiments were begun in 1899 to determine the most desirable 

 time to seed clover in Michigan. From results secured up to the 

 present time from April to June seems to be the most satisfactory 

 time for seeding. 



Corn experiments, L, Foster and L. A. Merrill ( Utah Sta. Bui. 

 6G.,2^p. 101-117, ^p(/s. If). — Different varieties of corn were compared 

 and tests made of the relative value of deep and shallow tillage, of hill- 

 ing and level tillage, and of thick and thin planting. Earlier results 

 secured along these lines at the station have been noted (E. S. R., 

 6, p. 527). While corn does not produce as much forage per acre in 

 Utah as alfalfa, it is considered a valuable adjunct to the latter and 

 a desirable crop to grow in rotations, taking the place of an occa- 

 sional summer fallow in freeing the land from weeds. The climatic 

 conditions for growing corn are not especially favorable in Utah, the 

 .seasons being rather too short and the general temperature too low, 

 especially the night temperature. It has been demonstrated, however, 

 that "all of the best flint varieties, the small dents, and the semidents 

 will fully mature in the localitj'of the experiment station." The dent 

 varieties, however, after being a few j^ears under cultivation tend to 

 take on the appearance of the flints. From 3 to 5 irrigations were 

 given in the different years. 



The 3'ield of IT varieties, including flint, dent, and semiclent corns, 

 during periods of .5 to 10 years, are tabulated by years and averaged. 

 A white flint corn, the varietv usuall}' grown in the Cache Valley, 

 has given the largest yields in 7 out of 10 years, and the highest aver- 

 age by 0.8 bu. of all the varieties tested for 10 years — •4G.22 bu. 

 per acre. Next in order of productiveness are Angel of Midnight, 

 North Dakota, and Golden Beauty, all flint varieties. The average 

 number of days from planting to cutting corn in Utah has varied with 

 the varieties tested from 116 days in the case of Vf hite Flint to 1.51 

 da^'s with Long Yellow Flint. 



In the deep and shallow tillage experiment, corn was given shallow, 

 medium, deep, and no tillage, and was scaritied and mulched with 

 sowed dirt. The test covered 5 years and the results are tabulated 

 for each year. On the whole medium tillage has given slightly the
