 tliis «iiiii* farm sumiiu'r fallowiiij^ sIiowimI a <^rcat advantage over spring phiwiug for 

 wheat. The yii'Ms from Ht'k'cled, well cleaned, and small seed at the farm for the 

 Northwest Territories were 37ii, '^-h ^nd 29;'( hu. per acre, respectively. On fallow 

 and new ground at this station fair yii'lds were obtained, V)ut on land whicli had 

 produced root crops the year before the growth of straw was abnormal, and an 

 attack of rust largely reduced the yield and <iuality. A culturt> test of winter wheat 

 at this farm was a complete failure. 



(kits. — At Ottawa the best yield on sandy loam was obtained l)y sowing li bu. of 

 seed per acre and on clay loam l)y sowing 2j liu. At the experiment farm for the 

 Northwest Territories, selected, well cleaned, and small oats for seed yielded 86/y, 

 80}2, and 72yV bu. per acre, n'si)ectively. 



Barley. — Different (juantities of seed ranging from l\ to 4 bu. per acre were sown 

 on sandy loam and clay loam soil at Ottawa. On the sandy loam the Ijest yield was 

 45 bu. per acre, obtained from 4 bu. of seed, and the next best from the use of only 

 IJ bu. On the clay loam soil 2 bu. of seed per acre gave the highest yield. 



Spelt. — The yields of spelt sown on May 6, 13, 20, and 27 at the Manitoba farm 

 were 59, 52, 56, and 61 bu. per acre, respectively. Sowing at the rate of 87J lbs. of 

 seed per acre proved most i)rofitable, the yield per acre being 54 bu. 40 lbs. At the 

 station for the Northwest Territories a yield of 36 bu. 20 lbs. per acre was obtained 

 and the crop required 108 days to mature. 



Corn. — At Ottawa, Champion White Pearl, Selected Learning, and Longfellow were 

 sown in rows 21, 28, 35, and 42 in. apart. Champion White Pearl yielded best in 

 rows 35 in. apart, and Selected Learning and Longfellow in rows 28 in. apart. At 

 the farm in the Maritime Provinces the yields of these same varieties were all in favor 

 of 28 in. between rows. At the Manitoba farm where these varieties were grown in 

 rows 24, 30, 36, and 42 in. apart the average yield of green corn per acre amounted 

 to 15 tons and 1,328 lbs., and was in favor of the greatest distance. The yield at the 

 farm for the Northwest Territories was in favor of 35 in. with Selected Leaming and 

 Longfellow, and 42 in. with Champion White Pearl. At the British Colundjia farm 

 this same experiment was made but with the addition of plats planted in hills. The 

 corn planted 6 in. apart in 21-in. rows gave the best yields in all cases, while the 

 hill-planted crop of Cham])ion White Pearl was in favor of 21 in., and that of the 

 other 2 varieties in favor of 28 in. The highest average yield of green crop was 

 obtained in drills. 



Potatoes. — Experiments in planting at different dates have been conducted at 

 Ottawa for several years. Plantings of an early and late variety were made at inter- 

 vals of 2 weeks until late in the season. In 1902 the planting made May 15 gave the 

 best results. The experiments, in general, have shown that a good crop of market- 

 able potatoes can he obtained at Ottawa by planting as late as July 10. The best 

 total average yield with the early as well as the late variety was obtained l)y planting 

 during tlie last week of May. The average results of a 7-years' test of planting at dif- 

 ferent distances show that planting in rows 2j ft. apart, with the sets 14 in. apart in 

 the row gave the best yields. For 6 consecutive years the largest yields were 

 obtained in sandy loam soil from planting the sets 1 in. deep. For field culture 

 the author recommends planting from 4 to 5 in. deep. While the largest yields have 

 been obtained by planting large whole potatoes it is believed most economical to use 

 medium to large tubers cut into sets having at least 3 eyes with a good amount of 

 flesh. In a fertilizer test with superphosphate of lime at the British Columbia farm 

 the yield per acre on the check plats was 355 bu. 18 lbs., while on the jilats receiving 

 100, 150, and 200 lbs. of superphosphate of lime per acre the yields were 371 bu. 

 48 ll)s., 391 bu. 36 lbs., and 409 Ini. 12 lbs., respectively.
