FIELD CROPS. 



An analytical study of the roots ami upper portions of the plants of Medium Gr< 

 and Ogemau soy beans, New Eracowpeas, V. globom, second crop June clover, and 

 new seeding June clover showed that on the basis of normal yields of forage per acre 

 Medium Green soy I trans yielded 152.29 lbs. of nitrogen per acre; the cow peas, 61.90 

 ll)~.: tin- vetch, 77.10 lbs.; the Becond crop clover, 51.47 lbs., and the new Beeding 

 clover, 19.06 lbs. 



On September 15, 1904, 13,590 lbs. of soj beans were harvested and put into the 

 sil<>. The silage taken from the silo the lasl week of April, 1905, had a peculiar and 

 unpleasanl odor. When weighed out it amounted to 1 1 .- s "> lbs;, and had the follow- 

 ing composition: Water us. '.»7 percent, ash 5.69, ether extracl 2.97, crude fibei 9 

 protein 3.28, and carbohydrates 10 per cent. It was fed to dairy cows. 



•• I nasi unci i as the Boy I 'cans do no1 grow tall and do noi therefore Btay bound in 

 the bundle with the corn when cu1 with the harvester, and inasmuch as repeated 

 experiments at this station show thai the vines of the Red Speckled and of the 

 Southern Prolific beans cling to the corn and arc harvested with it. it is suggested 

 that one or the other of these legumes be used instead of soy beans for enriching in 

 protein the corn in the silo." 



Trials with alfalfa, J. II. Shepperd | North Dakota Sta. Bui. 65, pp. 550-556, ph. 

 .'i. -The results of 4 years' trials with alfalfa, and for the mosl part previously 

 reported in former publications of the station, arc reviewed. 



The experiments at the station have indicated that alfalfa should be sown without 

 a nurse crop on well prepared land at the rate of 15 lbs. of se<^<l per acre. The com- 

 mon commercial -trains of alfalfa seed were found not to i„- well adapted to the con- 

 ditions of the region, and this has induced the station to breed hardy strains. In 

 1904 the yield of hay from the first mowing of Turkestan alfalfa seeded in pun vvas 

 at the rate of 3,600 lbs. per acre, and the second growth, which had Keen hindered 

 by extremely dry weather, gave 1,000 lbs. of hay per acre. \ plat of the same 

 variety seeded in 1902 yielded 1,200 lbs. of hay per acre on June 21, and 1,880 lbs. 



from the second cutting. 



Grimm alfalfa showed a good stand in 1904, hut did not grow as high as the 

 Turkestan. The yield of hay from the first cutting was .■'>.7l'i> lbs. per acre. The 

 second growth, although not quite mature when killed by frost, was harvested for 

 seed. It is believed that the trials indicate that alfalfa may ultimately prove a 

 successful crop in the State. 



Experiments in clover growing-, J. II. Shepperd (.\mlh Dakota Sta. Bui. 65, 

 pp. 54S-550, ph. /i.— The clover trials made by the station during 12 years are 

 review ed. 



It was found that seeding clover, or clover and timothy, with a grain drill gives 

 much greater assurance of a stand than broadcasting. With one exception during 

 '.i years, medium red clover seeded with a nurse crop passed through the first winter 

 without killing out. Allowing the second growth to remain asa winter protection 

 gave good results in preventing winterkilling and in reenforcing the stand by means 

 of the new seed. 



It was observed that the average stubble held was in most seasons efficient as a 

 winter protection. Inspection after each of ll winter seasons did not reveal a case ol 

 heaving by frost. Where an ice sheet covered the plants, however, the clovers, 

 alfalfa, timothy, and redtop were killed out, while brome grass and the weed quack 

 grass had withstood this adverse condition. 



Satisfactory results have been obtained from using 15 lbs. of clover seed per acre, 

 and a mixture of :> lbs. of red clover seed and s lbs. of timothy has given a mixture 

 of from one-half to three-fourths of timothy plants in the resulting stand. Ten lbs. 

 of Mammoth clover with 4 lbs. of timothy se< d have given an average of more than 

 three-fourths clover in the hay. The results for 4 years show a difference of only
