FIELD CROPS. 947 



Only one sample of barnyard millet was secured, and it is believed 

 that the analysis does not fairly represent its average composition. 



The average cost of production was 75 cts. per ton for the cereal 

 crops and $1.33 per ton for the leguminous crops, exclusive of the 

 crimson clover. 



A study was made of 2 soiling crop rotations, and tlie results are 

 reported in detail. Both proved exhaustive to the soil. The method 

 of fertilization followed in the experiments as described above is recom- 

 mended. 



The lodging of grain, Julten and Dupont (Ann. Agron., 24 {1898), 

 Xo. 11, pp. 534-518). — A study was made of the lodging of grain in the 

 experimental fields at Grignon, where 2 plats of wheat lodged June L>5 

 after violent rain and wind storms had prevailed, while the grain on 2 

 other plats remained intact. The conditions were the same for all these 

 plats. It was found that the lodged grain had been attacked by 2 

 fungus diseases, TJry.siphe graminis and Ophiobolu.s graminis, which 

 weakened the steins and caused them to lodge. Of the lodged plants 

 15 per cent failed to ripen their grain, while of those which remained 

 standing only 1 per cent failed to produce ripened grain. Grain had 

 lodged in previous years on the plats which produced the lodged grain 

 this season, and the authors believe that the spores which remained in 

 the soil germinated under favorable conditions and caused the spread 

 of the disease and the ultimate lodging of the grain. Burning the 

 stubble after the grain has been harvested is recommended as a remedy. 



The yield and composition of the lodged and unlodged grain were 

 compared. It was found that wheat aud oats were similarly affected 

 by lodging. The composition of the harvested grain from the lodged 

 and the unlodged plats was about the same, but the kernels on the 

 lodged plat were reduced in number and in weight, thus diminishing 

 the yield considerably. 



The stooling of grains, B. C. Buffum (Wyoming Sta.Bul. 37, pp. 

 207-242, ph. 2).— Experiments to determine the relative tillering of 

 wheat, oats, and barley were carried on at Laramie and at 1 substations 

 in the State for 2 years in succession. 



In 1896 seeds were planted 1, 2, 4, and 12 in. apart in rows 3 ft. 

 apart; and in 1897 the experiment was repeated on a somewhat larger 

 scale. In addition to these tests small plats were planted with different 

 amounts of seed per acre to determine results in actual field practice. 



The results are tabulated and discussed and also presented graph- 

 ically. The effects of altitude and irrigation on the stooling of grains 

 are discussed, and some practical hints in grain growing at high alti- 

 tudes are given. 



In general the results show that the number of mature heads pro- 

 duced by each seed varies greatly with the locality and the season, and 

 that the number of heads and the amount of grain produced increases 

 rapidly with the space given each seed. It was found that plants
