644 EXPERIMENT STATION RECORD. • [Vol.43 



Ten cords of manure per acre have been compared annually for IG consecutive 

 years with fertilizer containing an average of 96 lbs. of nitrogen, 170 lbs. of 

 phosphoric acid, and 150 lbs. of potassium oxid, which is about the equivalent 

 of 2,500 lbs. 5:6:6 fertilizer. The soil has been tilled each year and various 

 garden crops grown fairly intensively most of the time, although some atten- 

 tion has been given to cover crops for green manuring. 



After the first few years the crops have generally grown better with tlu' 

 manure than with the fertilizer. It is suggested that this may be due to the 

 smaller amount of nitrogen applied in the fertilizer as compared with thai 

 applied in the manure. At the end of the tirst decade there was about 800 lbs. 

 more nitrogen in an acre-foot of the manure area than of the fertilizer area, 

 A^'hereas the amounts of the other fertilizer elements were more nearly alilw. 

 In continuing the work it is intended to apply considerable nitrogen compound.*^ 

 during the growing season in an attempt to (Offset any advantage which may 

 have been derived from the larger residue of nitrogen in the manure plat. It 

 is pointed out that in case this treatment does not equalize the production be- 

 tween the manure and fertilizer plats, indirect evidence will have been ob- 

 tained that the additional humus-forming material in the manure was in some 

 way responsible for its greater efficiency. 



The farm garden, F. E. McCall {Proc. Amer. Soc. Hort. Sci., 16 {1919), pp. 

 188-190). — A contribution from the South Dakota Agricultural College giving 

 the results of cooperative farm garden demonstrations conducted on 12 farms. 



Keeping qualities of Hubbard squash, G. W. Hood {Proc. Amer. Soc. Hort. 

 Set., 16 (1919), pp. 186-188). — A contribution from the University of Nebraska 

 giving the results of a storage test with Hubbard squash. 



With squash stored at a temperature averaging 40 to 50° F., and for a period 

 beginning November 1 and ending March 31, there was an average of 20 per 

 cent loss in weight. The loss from individual squashes ranged from as low as 

 9 per cent to as high as 40 per cent. The loss in weight materially increased 

 with the length of storage. The test indicates that storage may be continued 

 too long to be profitable, and under certain local conditions as to price and 

 market it may not pay to store at all. 



Varietal variations as seen in similar methods of training tomatoes, 

 G. W. Hood {Proc. Amer. Soc. Hort. Sci., 16 {1919), pp. 183-185).— A contribu- 

 tion from the University of Nebraska, in which the author presents evidence, 

 from pruning and training experiments with three varieties of tomatoes, tend- 

 ing to show that under field conditions the slightly greater amount of earlier 

 fruit produced by pruning and staking does not pay for the labor involved. 



[Report on fruits, shrubs, and flowers at the North Platte Substation] 

 {Nebraska Sta. Rpt. 1919, p. 26).— Of the fruits being tested at the substation, 

 cherries and plums yield abundantly, and there is some promise that apples 

 may be grown successfully for home use where the soil is properly tilled and 

 modern methods of spraying followed. Small fruits, such as currants, goose- 

 berries, and strawberries do well, but strawberries must be irrigated to secure 

 annual crops. Among the hardy shrubs that are entirely successful are spirea 

 Van Houttei, tartarian and other honeysuckles, mock orange, lilac, Siberian 

 pea tree, buckthorn, cut leaf sumac, golden elder, tamarisk, and others. The 

 tulip, peony, hollyhock, and dahlia are among the most easily raised flowers. 



Some results as to the response of fruit trees to pruning, W. H. Chandler 

 {Proc. Amer. Soc. Hort. Set., 16 {1919), pp. 88-101).— A contribution from Cor- 

 nell University, compi-ising a discussion of results secured with young fruit 

 trees. 



From the evidence at hand, the author is of the opinion that the increased 

 vigor of new growth in the vicinity of the cut following dormant pruning, and
