738 EXPERIMENT STATION RECORD. 



given on the Rnsso-Mediterranean traffic in macaroni wheat. The following varie- 

 ties, which have well-niai-ked characteristics and have attained a high reputation, 

 are briefly described: Gharnovka, Arnautka, Kubanka, Pererodka, Beloturka, Vel- 

 vet Don, Black Don, Sarui-bugda, Medeah, Pellissier, Candeal, Nicaragua, Wild 

 Goose, Missogen, and Polish. Meteorological data for the regions of Russia where 

 these varieties are largely grown and for sections in this country adapted to their 

 culture are tabulated. In discussing the climatic conditions of these regions the 

 author calls attention to the fact that " the normal yearly rainfall of the (Jreat Plains 

 at the one hundredth meridian, where wheat growing is at present practically non- 

 existent on account of the lack of drought-resistant varieties, is nearly 3 in. greater 

 than that for the entire semiarid Volga region, which is one of the principal wheat 

 regions of Russia, and which produces the finest macaroni wheat in the world." 

 Comparative notes on foreign and domestic macaroni are given and analyses of maca- 

 roni produced from different wheats are tabulated. The bulletin further treats of 

 the use of macaroni wheats for Vjread and of the preparation of semolina or flour 

 used in the manufacture of macaroni. 



Fertilizer experiments with wheat, J. Osterspey {Fuhling's Landw. Zfg., 50 

 {1901), Nos. IJ, ]>p. 417-423; 13, pp. 449-455). — This experiment was made with 

 higlily l)red and selected Squarehead wheat on a soil poor in lime. The purpose of 

 the work was to determine the effect of an application of phosphoric acid in the 

 forms of superphosphate and Thomas slag, and of a top-dressing of nitrogen as nitrate 

 of soda and sulphate of ammonia, in addition to a medium application of barnyard 

 manure. The influence of either the phosphoric acid or the nitrogen used with 

 barnyard manure was also studied. Superphosphate increased the yield when 

 applied in addition to barnyard manure, l)ut this increase w^as not sufficient to make 

 its use profitable, either when used alone or in connection with a nitrogen applica- 

 tion. The use of Thomas slag, however, at the rate of 1,500 kg. per hectare was 

 found economical in all cases. The average results of the application of sulphate of 

 ammonia at the rate of 100 kg. per hectare showed neither an increase nor a loss, 

 while 125 kg. of nitrate of soda per hectare given in 2 applications proved highly 

 profitable. The simultaneoususeof fertilizers furnishing phosphoric acid and nitrogen 

 produced a profit under those conditions only when the use of the one or the other 

 alone was profitable. 



HORTICULTURE. 



Report of the assistant in horticulture, A. T. Jordan {Neiu Jersey Sins. Rpt. 

 1900, pp. 213-255, ph. 4). — Experimental studies are reported on the effect of irriga- 

 tion, the relative effects of fertilizers with and without irrigation upon early and 

 total yield, and the effect of the addition of nitrate of soda. The results secured 

 with asparagus and a number of busn and orchard fruits in 1900 are recorded in 

 detail and compared with results secured the 2 previous years. The daily and 

 monthly precipitation for the season is also included. 



Asparagus (pp. 218-222). — Contrary to the results obtained in 1898 and 1899, unir- 

 rigated asparagus plats gave the larger early and total cut. Palmetto was the most 

 productive variety grown in 1900. The increase in early asparagus with this variety 

 was worth commercially $24.60, and the early and total cut $111.77, more than any 

 other variety grown. Plats fertilized with c(jmplete fertilizers have given the largest 

 early cut, while the lowest yields have regularly api)eared on the nitrate of soda plats. 

 The difference in favor of selected crowns as compared with commercial roots, which 

 was very marked at first, has been growing less and less each year, and in 1900 the 

 yields were practically identical. 



Blackberries (pp. 222-225). — Erie has been the most productive blackberry grown, 

 and Agawam the least. Irrigation increased the early yield in 3 out of 4 ciises, but
