228 EXPERIMENT STATION RECORD. [Vol.40 



from the time of planting. The results obtained are illustrated graphically for 

 each crop and fully discussed. 



A brief review of the literature dealing with the subject is said to indicate 

 that the largest number of plants to emerge and the largest yields obtained 

 usually followed sec-dings made from 1 to 2 in. deep. As a result of the pivsent 

 experiments, it was found that seedings made from 1 to 8 in. deep seemed to 

 have little effect upon the germination of the seeds studied, but the highest 

 germination usually occurred with Beedings made from 3 to 5 in. deep, especially 

 for those seeds most affected by depth Of seeding. Deep seeding retarded the 

 growth of small seeds and of those having poor germinating power inure than 

 that of larger seeds. Growth was usually more rapid when the seeds were 

 sown from l to 2 in. deep, especially with regard to the roots, and this rapid 

 growth is thought to hi- one of the primary factors causing larger yields from 

 shallow seedings. in general, the height of tin- plants above the soil decreased 

 as the depth of seeding Increased. Maximum growth above ground never oc- 

 curred from seeds BOWU deeper than 3 in. Small seeds sown below 3 in. failed 

 to reach the surface in 20 days. 



A drill for seeding nursery rows, C. E. Hill (Jour. Amer. Soc. Agnm.. 10 

 (1918\. A", 'i, pp. in:,, ice,). — A drill devised by the author and recommended 

 for use in seeding short nursery rows of different varieties or strains of field 

 crops is described. Greater speed and accuracy, operation by one man, ellmina- 



tion of mixtures, seeding possible on a windy day, and better germination than 



with hand seeding are claimed for the implement 



"The essentia] parts of the drill are a funnel into which the seed is dropped 

 by hand at the desired rate; a furrow opener; a tube which carries the seed 

 from the funnel to the furrow opener; and a carriage on which these parts are 

 mounted." The drill is said to be suitable for Bowing light, fluffy s,>ed such as 

 tall oat grass, which will not feed through the ordinary types of garden drill.

 152-155. 158-1CC. .lias. .>').- The results of variety ami cultural tests with oats. 

 wheat, barley, corn, alfalfa, and root crops conducted in Quebec and Manitoha 

 are reported. 



In date-of-seeding tests with small grains in Quebec, the fust Beedings were 

 made as early in the spring as possible, and later Beedings at Intervals of one 

 week for 4 weeks. The yields from the last seedings to the first varied from 

 53.13 to 73.1G bu. for oats, from 18.78 to 35. S3 bu. for wheat, and from 66. 18 to 

 60.78 bu. for barley. 



The value of pedigreed seed is discussed.

 The results of breeding and spinning tests and inanurial experiments with 

 cotton; variety tests with sugar cane, peanuts, and sweet potatoes; and field 

 tests with peas and beans are reported. 



Pen manure applied at the rate of 6 and 13 tons per acre was followed by 

 yields amounting to 1.350 and 1,400 lbs. of seed cotton per acre, respectively, 

 as compared with 1,280 lbs. from an untreated check. With a complete fer- 

 tilizer composed of cottonseed meal, acid phosphate, and sulphate of potash 

 the yield was 1.300 lbs. per acre. Refisque peanuts produced at the rate of 

 2,400 lbs. of cured nuts per acre In 1916. with a 3-year average yield of 1,760 

 lbs. Trinidad No. 1 sweet potatoes gave a yield of 14.W7 lbs. per acre
