FIELD CROPS. 411 



"(2) There is a regular decrease in the per cent of dry matter witli an increase in 

 the distance between the plants. 



"(3) There is a regular increase in the average size of the roots with an increase 

 in the distance between the ])lants. 



"(4) It appears from conclusions 2 and 3 that conditions increasing the average 

 size of roots increase their per cent of water. 



"(5) Yield increases with an increase in distance between plants in the drill to a 

 certain distance, which appears to be between 8 and 12 in., and beyond this it 

 decreases. 



"(6) More dry matter is jiroduced by thinning to a distance of 8 than 20 in. 



"(7) Roots tending to lengthen rather than broaden should be thinned to a dis- 

 tance of 8 or 9 iu. apart in thi; drill, otherwise the distance should be about 10 in." 



Experiments with rye, C, L. Xew.man {Arl-ausas iSta. Buh 28, 

 pp. 90-'Jo). — IJye planted in November iu drills 18 in. apart, ou heavily 

 maunred soil, was cut .3 times, and gave a total yield of 43,516 lbs. of 

 green forage per acre. The heaviest cutting, made April 28, yielded 

 20,4(50 lbs. of green forage which when cured made 9,261 lbs. of hay. 

 This hay contained 8.31 i)er cent of protein, and had a nutritive ratio 

 of 1:10, while hay made from rye cut several weeks earlier ''when in 

 boot" contained 13.25 per cent of protein with a nutritive ratio 

 of 1 : 5.2. 



The yield of green rye per acre on plats on which jiea vines were 

 turned under a few days beibre the rye was planted averaged 6,497 

 lbs. per acre. On plats similarly fertilized, but without green manur- 

 ing, the yield was3,7J5 lbs. of green rye per acre. Nitrate of soda, 

 muriate of potash, acid phosphate, and all three combined were more 

 effective when used ou rye following peavines than when applied to 

 rye which had not been preceded by a green manuring crop. 



Sugar beets, N. E. Wilson (Xevada Sta. Bui 23, pp. 5^).— Tabulated 

 data giving composition of samples of beets analyzed in 1891, 1892, and 

 1893; notes on the culture of beets; extensive quotations dealing with 

 the work done at Schuyler, Nebraska, by the Division of Chemistry 

 of this Department; and statistics relative to the yield and consump- 

 tion of sugar in the United States, and the cost of manufacturing 

 sugar in this country and in Europe. At the station all samples of 

 beets analyzed in 1891 averaged 13.20 ])er cent sucrose with a purity of 

 76.87; those grown in 1892 averaged 15.56 per cent sucrose and 80.76 

 purity; those grown in 1893, 14.23 per cent sucrose and 80.76 purity. 

 The experiments for 1893 here reported closed the work of the station- 

 in this special line. 



Varieties of sugar cane grown in Antigua in 1893, F. Watts 

 [Huppl. Leeirard IxJandti Gaz., isfJl, June 21). — Of 14 varieties of sugar 

 cane grown on well-tilled calcareous soil Rap])oe gave the largest yield 

 per acre of cane sugar in the juice, namely, 4,907 lbs. Of 16 varieties 

 grown on stiff nou -calcareous soil Keni Keni gave the largest yield of 

 cane sugar in the juice, 4,593 lbs. Analyses of the canes and of their 

 juices are given.
