tbe series being completed in 5 years, with crops of wheat and soy beans in the 

 final year. The manured section received barnyard manure at the rate of 14 tons 

 per acre in the spring of 1902, with no further application of any Icind since that 

 date. After the wheat was harvested in June, 1904, all plats were disked twice 

 and a third disking was given about the first of July after heavy rains had 

 fallen. The plats were seeded to soy beans on July 12 and 13 in drills 32 iu. 

 apart at the rate of about 30 lbs. of seed per acre. The unmanured plats yielded 

 ll.G bu. of l)eans and 0.68 ton of straw, and the manured plats 17.G bu. of 

 beans and 1.02 tons of straw per acre. This crop matured in 79 days. 



In a variety test with cowpeas, conducted iu 1903, Whip-poor-will produced 

 a more vigorous growth of vines and gave a larger yield than California 

 Black Eye. The Iron cowpea gave a heavy yield of forage but a low yield of 

 gi-ain. In 1904, 5 varieties of cowpeas were compared, and in this test the White 

 Era led in yield of grain with 18.20 bu. per acre, a local variety somewhat 

 resembling Whip-i)oor-will standing next with 13.59 bu. The Iron cowpea gave 

 the maximum yield of cured hay, with a low yield of seed. California Black 

 Eye ranked fli'st in earliness, requiring only 112 days to mature, while the other 

 varieties continued to grow and blossom for 142 days. 



In 1904 cowpeas and soy beans were compared on bottom and on upland soil. 

 The bottom land was seeded May 5 and the upland June 30. On the bottom 

 land the soy beans produced 0.70 ton of hay and 9.90 bu. of grain, and the 

 cowpeas 1.79 tons of hay and 8 bu. of grain per acre. On the upland area soy 

 beans produced 0.61 ton of hay and 9.45 bu. of grain, and cowpeas 1.07 tons of 

 hay and 12.45 bu. of grain per acre. 



Root crops for stock feeding, S. Eraser, J. W. Gilmore, and C. F. Clark 

 (New York Cornell .S7«. Bui. 2.',3, pp. //7-7'6, fig.'i. i5).— This bulletin deals with 

 mangels, sugar beets, turnips, hybrid turnips, ruta-bagas. kohl-rabi, carrots, and 

 parsnips, with a view to guiding those wishing to raise any of these crops under 

 New York State conditions. The value of root crops for forage is discussed 

 and the cultural experiments conducted for 3 years are reported. 



In 1904 the crops were sown early in.May and the middle of June on land part 

 of which had been in mangels for 3 years and the remainder under a rotation of 

 crops. The early sown mangels on the no-rotation areas were attacked by leaf 

 spot while young. The land received about 10 tons of barnyard manure per acre, 

 was plowed about 8 in. deep early in the spring, and harrowed 4 times. Four 

 hundred pounds of 17 per cent available acid phosphate was sown broadcast and 

 harrowed in. The land was rolled before sowing and the seeds put in with a 

 hand planter. The mangels were sown at the rate of about 8 lbs. of seed per 

 acre. Mangel and parsnip seeds were put in about f in. deep and all others i in. 

 deep. The mangels came up in 12 days and the cabbages, ruta-bagas, hybrid 

 turnips, and common turnips in from 5 to 6 days. The carrot seed was slow .in 

 starting and the parsnips were a failure. The ruta-bagas were sown at the 

 rate of 4 lbs., hybrid and common turnips rather less, and carrots at the rate 

 of (") to 7 lbs. per acre. The cultivation for all crops was the same. The hand 

 cultivator was used twice in May and the 1-horse cultivator on May 20 and every 

 2 weeks during June and July, and in the case of the late-sown crops until 

 August or until the plants met in the row. Common turnips were harvested 

 July 18 and all other roots from October 22 to 29. 



Sugar beets were also grow^n with and without rotation on a well fitted, rich 

 loam soil. This was replowed and fertilized with 1,000 lbs. per acre of a mixture 

 containing 4 per cent nitrogen, 5 per cent phosphoric acid, and 10 per cent 

 potash. In addition 1,500 lbs. per acre of air-slaked lime was applied. The 

 seed used was of the Kleinwanzleben variety, grown at Fairfield, Wash. The 

 seed was sown 2 to f in. deep at the rate of 12 lbs. per acre. The plants were
