FIELD CROPS. 1065 



out Ontario with a miinber of the same crops, Emiiicr led in yield with 1,908 lbs. 

 per acre, being followed by J\Iand«cheuri barley and Siberian oats, yielding 1,915 

 lbs. and 1,796 lbs. per acre, respectively. 



The results w'ith selected seed show that in the average of 7 years oats from large 

 seed produced about 8 bu. per acre more than from medium-sized seed, and 15J bu. 

 more than from small seed. Large plump barley seed gave nearly 8 bu. per acre 

 more than shrunken seed in the average yields for 6 successive years. Broken bar- 

 ley yielded an average of 10.6 bu. less per acre than large plump seed. Split peas 

 and broken wheat gave very poor results. The results obtained in 1903 from experi- 

 ments in tlie continuous selection of seed oats in progress for 11 years were as follows: 

 Large piumji seed, 76.9 bu. ; light seed, 57.7 bu., and hulled seed, 72.2 bu. per acre. 

 The crop from the large plump seed showed the heaviest weight per bushel. The 

 hulled seed produced the largest proportion of hulled grains. 



The greatest yield from different proportions of oats and barley was obtained this 

 season from one bushel of oats and ^ bu. of barley per acre. In a second test in 

 progress for 2 years the average results are in favor of a mixture of 1 bu. of oats, 1^ 

 bu. of barley, and J bu. of emmer, the yield being 2,673 lbs. per acre. The smallest 

 yield, 2,591 lbs., was obtained where grass peas were sown with the oats and l)arley. 

 Methods of cultivation for oats and barley have been compared in duplicate for 3 

 years on an average clay loam soil. The largest yield of grain per acre of both crops 

 was secured where the land was cultivated 3 in. deep and then drilled and rolled. 

 Different treatments for the prevention of smut in oats and winter wheat were again 

 tested, and the results were practically the same as those in previous years. 



A comparison of seed wheat and seed oats from Missouri and Ontario is in progress, 

 and the results to date show that the southern oats produced the largest yield, while 

 the Ontario oats were best in quality. This season Dawson Golden Cliaff wheat 

 from Ontario gave slightly better results than that obtained from Missouri. 



The average results obtained from sowing 2 varieties of winter wheat on different 

 dates for 9 years indicate that the seeding should be done the last week of August or 

 the first 10 days of September. For 6 years spring wheat, barley, oats, and peas were 

 sown on 6 different dates, the first seeding being made as soon as the ground was in 

 proper condition, and the others at weekly intervals afterwards. The average results 

 were in favor of the earliest seeding with spring wheat, and of the second seeding 

 with the other crops. It is further indicated that the order of sowing should be as 

 follows: Wheat, barley, oats, peas. After the first week the average decrease in 

 yield per acre for every day's delay in seeding amounted to 56 lbs. with oats, 53 lbs. 

 with barley, 29 lbs. with spring wheat, and 23 lbs. with peas. Spelt and emmer were 

 sown this season at weekly intervals on 8 different dates, beginning with April 2. 

 Emmer produced more straw and a heavier grain than spelt from each of the seed- 

 ings. For the first and the last dates of seeding for emmer and spelt the yields of 

 grain were 4,297 and 3,103 lbs. and 3,499 and 658 lbs. per acre, respectively. 



Sowing wiiiter wheat at the rates of 1, IJ, and 2 bu. per acre gave average yields 

 for 6 years of 40.2, 43.3, and 43.9 bu. per acre, respectively. Broadcasting the seed 

 by hand gave practically the same results as drilling it in with a machine. In one 

 test, winter wheat after field peas, used as green manure, procluced an annual aver- 

 age of 22.1 per cent more wheat per acre than after buckwheat plowed under; and 

 in a second test, a crop following clover stubble produced 20.7 per cent more grain 

 per acre than a crop following timothy stubble. In a 2-years' test 160 lbs. of nitrate 

 of soda per acre increased the yield 18.8 per cent, or 7.2 bu. The results of 7 years' 

 work show that the heaviest grain was obtained from thoroughly matured seed.
