536 EXPERIMENT STATION RECORO. 



spring wheat 30, and peas -1 per cent. A\'itli a delay in sowing of 4 

 weeks, the average loss with oats has been -is, l)arley -J-B, spring wheat 

 56, and peas 30 per cent. These results are largel}' in harn)onv with 

 like data reported from the branch stations. Early sowings of man- 

 gels, carrots, and beets at all the stations have resulted quite uniformly 

 in favor of the practice. At the Central Station the yield of potatoes 

 decreased regularh' with the lateness of planting after May 26, when 

 the first crop was put in the ground. With the flax crop in 181H> the 

 results in the Maritime Provinces, Northwest Territories, and British 

 Columbia seem to be in favor of medium sowings. 



In the distance experiments, corn was grown in rows 14, 21, 28, 35, 

 and 42 in, apart, respectively. In general the heaviest 3-ields of green 

 silage corn were obtained from the rows 21 and 28 in. distant, when 

 cut in the early milk stage. With soy beans and horse beans the 

 largest yields at Ottawa, Manitoba, and the Northwest Territories were 

 obtained when the rows were 21 in. apart. Twenty-four in. for soy 

 beans and 30 in. for horse beans were found to be the best distances in 

 the Maritime Provinces; while 35 for soy beans and 28 for horse beans 

 were found best in British Columl^ia. Leaving a part of the turnips 

 in the ground 3 weeks after the first pulling, October 14, resulted in 

 considerably increased yields at the Ottawa Station. 



Spring-plowed land has usually proved better than fall plowed for 

 wheat in Manitoba, while summer fallowing has given better results 

 than either. Seeding wheat with a press drill has given better aver- 

 age yields of grain for 8 years in the Northwest Territories than seed- 

 ing with a hoe drill. Likewise at the same station seeding wheat 2 in. 

 rather than 3 in. deep has given the better average results for the same 

 period, while the use of li to li bu. of seed per acre has resulted more 

 satisfactorily than when only 1 bu, per acre has been sown. 



Of all the different fertilizers used at the Central Farm on spring 

 wheat, barle}', corn, mangels, and turnips, the best average results for 

 12 3'ears have been obtained with ])arnyard manure (about equal parts 

 horse manure and cow manure), and slightly better results have been 

 secured from the use of fresh manure than from well-rotted manure. 

 At the same station oats grown after grain crops seeded with clover in 

 1897 gave an increase in yield of straw of 17 per cent in 1898 and 35 

 per cent in 1899; and of grain of over 28 per cent in 1898 and 29 per 

 cent in 1899, as compared with the yield from the grain plats on which 

 no clover had been turned under. 



Growing oats after pasture grass and clover has resulted in better 

 yields of grain than growing after either brome grass, pasture grass, or 

 barley seeded with clover. Potatoes grown after a crop of barley and 

 clover gave a 28 per cent higher yield than when grown after peas 

 and carrots.
