538 EXPERIMENT STATION RECORD. 



On the wired plats the tops or straw of all crops was larger than on 

 the section not wired. 



The largest yield of mangel-wurzel roots was obtained on the wired 

 section ; the largest yield of turnip roots on the section not wired. The 

 largest yield of grain was obtained in every case on the wired section. 



Experiments with wheat, 0. G. Georgeson, F. 0. Burtls, and 

 D. J I. Otis [Kamas Sta. Bui. 17,2>p. 11-16). — Very cold weather late in 

 March following warm weather in the earlier part of the month and a 

 freeze on May 20 made the wheat crop almost a complete failure on the 

 station farm, and hence the following exiieriments were abandoned for 

 1804: 



Hot- water treatment for stinking smut, methods of seeding, seeding 

 at different dates, early and late i^lowing for wheat, intluence of the 

 quality of seed wheat on the yield, effects of compacting the seed bed, 

 amount of seed wheat per acre, and effects of pasturing wheat. 



Tlie yields made on the plat grown continuously without manure 

 and on the rotation plats are tabulated, but no conclusions are drawn. 



" [Of 51 varieties tested iu 1894] the Tiii-key stood the Marcli freeze better than 

 any other variety, it beinj;' somewhat tardy iu its growth, and, in conseiinencc, it 

 shows the best yield, an average of 8 plats giving a yield of nearly 27i bu. to the 

 acre. This variety is held in high esteem iu many parts of the .State, and it may 

 properlj"^ be classed with our most productive wheats. . . . Although the Currell 

 suffered badly, we still consider this our best wheat." 



Field experiments with wheat, E. L. Bennett and G. B. Irby 



{Arkansas >Sta. Bui. 29, pp. 115-127, Jig. 1). — These experiments were 

 conducted on sandy soil at the Newport Substation. Neither acid 

 phosphate, kainit, nor gypsum used alone increased the yield of wheat. 

 Cowpeas planted July 31 and plowed under October 10 (about 2 weeks 

 before wheat was sowed) increased the yield of wheat over the plat 

 without green manure nearly 12 bu. per acre. A plat upon which cow- 

 pea vines without the peas had been turned under in October produced 

 15 bu. 30^ lbs. of wheat per acre. When the peas were not removed 

 from the vines the yield was 18 bu. 10 J lbs. of wheat i)er acre. The 

 yield of peas and hulls was 1,160 lbs. per acre, an amount sufficient to 

 pay the cost of picking and the loss of wheat resulting from removing 

 the peas. When the pea vines with immature pods were turned under 

 July 31 the yield was 14 bu. 32 lbs. of wheat. 



Deep and shallow preparation of the soil for wheat produced practi- 

 cally no difference in the yield, nor was there any great difference iu 

 the yield of wheat produced by the use of native seed or seed from 

 Missouri and Michigan. 



The bulletin also contains a brief report on an experiment on the 

 time for planting wheat and brief notes on grain insects. 



Time of irrigating fall wheat, A. A. Mills ( Utah 8ta. Rpt. 1893, pp. 

 214-216). — Of 5 i^lats seeded with fall wheat 4 were irrigated, the num- 

 ber of irrigations and the time of irrigation varying. The yields of fall
