334 EXPERIMENT STATION RECORD. 



Three plats of hay, fertilized with noO lbs. of nitrate of soda and the same 

 amounts of nitrogen in sulphate of ammonia and lime nitrogen, gave results in 

 the first two cases of approximately 2 tons 480 lbs. of hay per acre, and 1 ton 

 1.994 lbs. for the lime nitrogen. Other plats of hay showed an increased yield 

 of 1,180 lbs. per acre in case of plats fertilized with 125 lbs. nitrate of soda per 

 acre as compared with the check plats. The application of an equivalent 

 amount of nitrogen as basic nitrate of lime and of nitrate of lime gave in- 

 creased yield of COS lbs. and 400 lbs. per acre, respectively. 



Plats of mangels showed a difference of but 870 lbs. per acre in favor of an 

 application of 2 cwt. of nitrate of soda per acre, as compared with the same 

 amount of nitrogen supplied in lime nitrate when each was applied with 10 

 tons of manure and 400 lbs. of superphosphate per acre. This difference 

 increased to 2h tons per acre when each was applied in one and one-half times 

 as great quantity with superphosphate and kainit. 



On other plats there was an increased yield of 2 tons 1,305 lbs, of mangels 

 over that of the check plat in case of lime nitrogen, of 5 tons and 720 lbs. in 

 case of nitrate of soda, and of 4 tons 1,130 lbs. in case of sulphate of ammonia. 

 Each of the fertilizers was ajiplied in drills in the spring in amounts to supply 

 per acre the amount of nitrogen contained in 250 lbs. of sulphate of ammonia, 

 except that one-half of the nitrate of soda was reserved for later application 

 as a top-dressing. 



In the potato plats there was a difference in yield of 1,600 lbs. per acre in 

 favor of an application at the rate of 100 lbs. per acre of sulphate of ammonia 

 over the same amount of nitrogen supplied in lime nitrate when each was 

 applied with manure, superphosphate, and sulphate of potash. The difference 

 increased to 2 tons and .50 lbs. wlien twice the amount of nitrogen was applied 

 in each form in mixture with larger amounts of superphosphate and sulphate of 

 potash. Lime nitrogen gave a slightly higher percentage of merchantable 

 potatoes. 



Another series of plats gave yields of potatoes differing but 1,750 lbs. per 

 acre when fertilized with 150 lbs. of sulphate of ammonia and an equivalent 

 amount of nitrogen in lime nitrate, each mixed with sulphate of potash and 

 basic slag. 



The Vilmorin and Klein Wanzlebeu varieties of sugar beets produced nearly 

 3 tons more of roots per acre than did the Aderstedt variety. Roots gi'ow^n in 

 drills 20 in. a])art were slightly smaller than those growni in drills 27 in. apart, 

 but excelled them in yield, percentage of dry matter, and percentage of sugar 

 in juice, the sugar yields per acre being 2.25 tons and 1.75 tons, respectively. 

 The effect of manuring on the sugar content was variable and within the limits 

 of experimental error. 



Eeport of the Aligarh Agricultural Station of the United Provinces of 

 Agra and Oudh, for the year ending June 30, 1909, A. E. Parr (Ri)t. Aligarh 

 Agr. Sta. United Prov. Agra unci Oudh, 1909, pp. 5, map 1). — The experiments 

 rei)orted were mainly with cotton. The American variety, Watagodu, produced 

 21.4 per cent more when sown early with irrigation than when sown early with 

 rains. Mixed country cotton showed a difference in favor of planting wnth rains 

 instead of irrigation of 32.7 per cent. Although at the station American cotton 

 liroduced lower yields than did the ordinary country cotton, the crops grown by 

 private individuals in the district showed opposite results. 



Hybrid American cotton produced 21.4 per cent greater yield on ground 

 plowed early and plowed three times than on ground plowed but once and that 

 immediately before sowing. Another American cotton produced a yield 21.8 

 per cent greater when sown after the plow in rows 3 ft. apart than when 

 broadcasted.
