FIELD CROPS. 841 



The average sugar content of the beets was 18.2 per cent for plats 

 fertilized with barnyard manure, 17.8 per cent for plats fertilized with 

 barnyard manure and nitrified soil, and 17.1 per cent for the plats 

 fertilized with barnyard manure and nitrate of soda. 



Experiments with sugar beets in Norway in 1897, B. Larsen 

 (Norsk. Landmansblad, 17 {1898), No. 7, pp. 77, 78; Tidsskr. Norske 

 Landbr., 5 (1898), No. 2, pp. 80-89). — This is a report on cooperative 

 experiments with different kinds of sugar beets conducted under the 

 direction of the agricultural experiment station at Aas, Norway. The 

 experiments were made at 18 different farms. The average percentage 

 of sugar in the beets obtained was 12.68 per cent and the average 

 weight of beets was 358 gin. The beets grown at the Aas Experiment 

 Station had an average sugar content of 13.19 per cent with a range 

 from 12.7 to 13.5 per cent. — P. w. woll. 



Experiments at the Derebchinskoe experiment field of Baron 

 A. A. Mas, F. Lynbanski (Kiev, 1897, Vol. IX, pp. 176; abs. in Selsk. 

 Khoz. i Lyesov., 188 (1898), No. 2, pp. 471, 472). — Experiments were 

 made to determine the influence of depth of plowing, size of seed, and 

 the use of commercial fertilizers on the yield and quality of sugar beets. 

 It was found that by plowing the soil at depths varying from 7 to 10£ 

 in., the yield increased with the depth of plowing, but that the sugar 

 content suffered a loss. Beets grown from large seed gave better yields 

 and were richer in sugar than beets grown from small seed. A liberal 

 use of nitrogenous fertilizers increased the yield considerably but 

 decreased the sugar content to some extent. 



A test was made of nitrate of soda as a top-dressing for oats and 

 barley. The result showed an increase in the yield of each crop and 

 an increase in the phosphoric acid content of the barley. — P. fireman. 



Experiments with sugar beets at the experiment station of 

 Count Bobrinski at Smyela, Kiev Government, Russia, V. Bond- 

 iryev (Selsk. Khoz. % Lyesov., 184 (1897), pp. 165-176). — Fertilizer 

 experiments with sugar beets were made on a Chernozem soil, rich in 

 nitrogen and containing over 0.02 per cent available phosphoric acid 

 but comparatively poor in potash and lime. The fertilizers, lime, pot- 

 ash, nitrate of soda, and superphosphate, were applied on plats of 525 

 sq. ft. each. The lime refuse from sugar factories was used as the lime 

 fertilizer. 



The nitrogenous fertilizer showed a tendency to deform the beets but 

 increased the size of those parts which are rejected at the factory, while 

 the other forms of fertilizers had the opposite effect. The sugar con- 

 tent and purity of the juice was decreased by the use of the nitroge- 

 nous fertilizer and lime, but the yield of beets was increased to some 

 extent. The potash and superphosphate improved the quality and 

 increased the quantity of the crop. The greatest increase in sugar was 

 due to the potash fertilizer.
