Early sowing of mangels apparently increiised the yield over late sowing by 

 about 2 tons per acre, and with tui'nips by about 4 tons by the early sowing. 

 The fertilizing effect of clover was shown by yields of 37 bu. 5 lbs. of wheat 

 following red clover sod. 33 bu. 30 lbs. following alsike clover, 27 bu. 37 lbs. 

 following western rye grass, and 26 bu. 47 lbs. following timothy. 



At the southern Saskatchewan farm, flax gave a better yield of straw, 1 ton 

 1,672 lbs. per acre, when planted May 30 than when planted May 5. but a better 

 yield of grain, 34 bu. 36 lbs., from the earlier planting. 



At the northwestern Saskatchewan farm, in a test of seeding spring wheat 

 in quantities from | to 2i bu. ]>er acre, the yields of grain ranged from 

 2 bu. 5 lbs. per acre with the smallest amount to 5 bu. 20 lbs. with the heaviest 

 seeding. A similar test was made with oats, but the plats were almost wholly 

 destroyed by storm. Oats sown with the drill machine set at the shallowest 

 notch gave better yields of grain than when set at the deepest notch. 



At the southern Alberta farm, the average yield of 3 years for alfalfa, seeded 

 at the rate of from 5 to 30 lbs. per acre, was heaviest vtrith the 15-lb. rate, 

 although closely followed by the 10 and 30-lb. seeding. Planting potatoes 2 ft. 

 apart gave a relatively larger return than planting at 1 ft. On irrigated land, 

 the highest average yield of wheat for 4 years was obtained by using 105 lbs. of 

 seed per acre, whereas 90 lbs. of oats and barley is considered the most satis- 

 factory. Comparisons of irrigated and nonirrigated land for growing seed 

 potatoes were inconclusive. 



At the central Alberta farm, substantially the same yields of winter wheat 

 followed the use of i bu. of seed per acre as with 2 bu., both being larger 

 than those with intermediate rates. Seeding oats May 5 was followed by a 

 yield of 67 bu. 2 lbs., as compared with 38 bu. 28 lbs., 42 bu. 12 lbs., and 35 bu. 

 10 lbs. from seedings May 13, 20, and 27, respectively. The average net profit 

 per crop and per acre for 5 rotations tested ranged in 1911 from $3.40 to $17.92. 



Tabulated data show that en the British Columbia farm the yields of corn 

 were heaviest when sown 21 and 28 in. apart, but the stalks were much thinner, 

 filled with water, and of much less value than the corn sown at 35 and 42 in. 

 The labor of cultivating in drills was much greater than in hills. 



[Field crop experiments], J. M. Scott (Florida Sta. Rpt. 1912. pp. XXXI- 

 XXXVII).— This report includes trials of crops in which Yokohama beans, 

 maturing in about 120 days, yielded at the rate of 1,408 lbs. of beans in the pod 

 per acre ; Japanese cane yielded in 3-year tests from 11.91 to 19.03 tons per acre, 

 with sucrose in the juice ranging from 10.15 to 11.27 per cent ; Natal grass in 2 

 cuttings produceed 2,042 lbs. of cured hay per acre; guinea grass in 2 cuttings, 

 3.300 lbs. ; Para grass in 2 cuttings, 2,760 lbs. ; and kudzu grass, in 2 cuttings. 

 2,756 lbs. 



With an application of 45 lbs. sulphate of ammonia, 50 lbs. muriate of potash 

 and 175 lbs. acid phosphate per acre a yield was obtained of 366 lbs. seed cotton 

 per acre, as compared with 312 lbs. following the substitution of 75 lbs. dried 

 blood for the sulphate of ammonia. In some instances the use of 2,000 lbs. 

 ground limestone per acre apparently increased the yield of Japanese cane 

 50 per cent the first year. The cultivation of the cane to depths varying 

 between 2 and 6 in. showed little relatitou between the yield and the depth of 

 cultivation. 



Keport of the agronomist, C, K. McClelland (Flawaii Sta. Rpt. 1912, pp. 

 lJi-^2). — This is mainly a progress report of experiments with cotton, rice, 

 broom corn, grasses and forage plants, diy farming, and range improvement. 



Samples of Caravonica cotton were submitted to a carding and picking test 

 at a new England factory. Roller-ginned cotton suffered a loss of 7i per cent 

 in shrinkage or waste as against a 9J ijer cent loss by the saw-ginned cotton.
