HOETICULTUEE. 237 



Central Farm, Ottawa, and at the various branch experimental farms and sta- 

 tions in Canada. The details of the work are to appear as usual in the annual 

 report at a later date. 

 Among the commercial varieties of apples tested at the Central Farm Red 

 ^June, Stayman Winesap, and Rome Beauty give considerable promise, both 

 "with reference to hardiness and quality, although it is believed that Rome 

 Beauty should be tested further before recommending it for commercial plant- 

 ing in a climate as cold as that at Ottawa. The Delicious kills back and is not 

 considered hardy enough for commercial purposes in that region. 



Additional data are given on the closely planted Wealthy apple orchard 

 (E. S. R., 32, p. 437). The estimated net profit per acre in 1914 was $115.40, 

 the average net profit per acre from date of planting, 1896, being $90.49. Of 

 the original 144 trees there are now S8 left. 



In previous observations made for a number of years relative to the yields 

 of individual trees of the same varieties of apples there was found to be a 

 great difference in the yields from different trees (E. S. R., 27, p. 343). An 

 experiment in scion selection was started in 1905 in which scions taken from 

 the least productive tree, the most productive tree, and the tree which bore a 

 good crop every year in a row of 18 Wealthy apple trees were root grafted 

 and planted out in 1909 on a uniform piece of soil. The yields for the three 

 bearing years 1912 to 1914 indicate that the bearing habit of the parent tree 

 has been perpetuated in each case, although observations are to be made for 

 several years before definite conclusions are drawn. 



Of the autumn bearing strawberries being tested, the Progressive has thus 

 far given the best results. In 1914 this variety yielded a fair crop of fruit in 

 the regular season and also in the autumn, the fruit continuing to ripen until 

 injured by frost. The results for the first season of a test of European grapes 

 grown under glass are given. Data are also given on a series of experiments 

 with orchard heaters conducted at the farm in the fall. The data secured 

 indicate that these heaters may prove very useful in strawberry and truck crop 

 plantations, where the value of the crop is relatively high. The usual notes 

 are given on the more promising varieties of vegetables and ornamentals tested 

 both at the Central Farm and at the branch stations. Fertilizer tests with 

 potatoes are reported from the Fredericton, New Brunswick, substation, and 

 cultural tests from the Rosthern, Saskatchewan, substation. 



A series of tests was started in 1913 at the Kentville station, W. S. Blair 

 in charge, to determine the advisability of fertilizing fruit trees when they are 

 planted. The results to date indicate that there is little advantage in using 

 fertilizers at planting time and that good cultivation is of greater importance. 

 From two years' work carried on by this station in a number of cooperative 

 orchards, it appears that four thorough applications of lime-sulphur arsenate 

 of 1.008 sp. gr. will control scab as effectively as Bordeaux mixtui-e without 

 danger of russeting the fruit, which is usually more or less serious when 

 Bordeaux is applied after the blossoms fall. The application of a dormant 

 spray in addition to the regular sprays appears to be of little value in control- 

 ling scab. A test was made of the claim that sugar added to Bordeaux will pre- 

 vent russeting. The addition of 2, 4, and 6 lbs. of sugar, respectively, to 4 : 4 : 40 

 Bordeaux arsenate mixture proved to be of no value as a preventive of russet- 

 ing. A series of tests undertaken to determine the actual gain from arsenate of 

 lead in lime-sulphur for the control of scab indicated that the arsenate of lead 

 had very little fungicidal value. Commercial concentrate lime-sulphur appeared 

 as effective in controlling scab as the home-boiled concentrate.
