FIELD CROPS. 329 



Durin?: the 3 years 231 acres of cotton were grown wliicli produced for this 

 period an average yield of 49S.9 lbs. of lint per acre. In 1908 the results on 

 a tield of 13 acres showed that planting cotton level 85 ft. each way was 

 entirely too close when the crop made a large growth. The yield on this field 

 was 492 lbs. of lint per acre. Eight standard varieties of cotton were compared 

 to determine the relative yield of long and short staple varieties. The 1 in. 

 staple produced 1.82.5 lbs. of seed cotton, and G4.5 lbs. of lint, the 1| in. staple 

 1.780 lbs. of seed cotton and .570 lbs. of lint, the 1 i^e in. staple 1.72S lbs. of seed 

 cotton and olO" lb.s. of lint, and the lit in. staple 1,.5<X) lbs. of seed cotton and 

 43U lbs. of lint per acre. 



In a test of 14 varieties conducted in 190S, Cleveland Big Boll ranked first 

 with 1,503 lbs. of seed cotton and 548 lbs. of lint per acre, and Lewis Prize 

 second with 1,412 lbs. of seed cotton and 517 lbs. of lint. The average increase 

 from 300 lbs. of cotton-seed meal per acre for the 3 years was 100 lbs. of lint 

 cotton. Applications of phosphorus or potash failed to increase the yield. 



Notes are given on sorghum, red clover, drainage, and trucking. 



[Studies in the composition of field crops], F, T. Shutt (Canada Exi)t. 

 Farms Npts. 1<)07, pp. 135-152). — Chemical analyses of wheat, potatoes, man- 

 gels, turnips, and sugar beets are reported. 



The work with wheat was conducted to determine the composition of the 

 grain as influenced by environment. In the first experiment the wheat used as 

 seed contained 11.11 per cent of protein, and the product from this seed when 

 grown on recently cleared and broken land 9.93 per cent and when on summer 

 fallow 12.62 per cent. The newly broken soil in a second experiment ranged 

 from 9 to 14 per cent higher in soil moisture than the soil on the sununer 

 fallow. Both soils were rich in vegetable matter, and high in nitrogen. The 

 wheat used as seed on this soil contained 9.93 per cent of protein, the crop on 

 the newly broken land 10.1 i)er cent, and that on summer fallow 13.52 per cent. 

 The difference in favor of summer fallow in this experiment is considered as 

 possibly due to the larger amount of moisture in the newly broken soil. In the 

 third experiment of this kind the Red Fife seed wheat used contained 13.91 per 

 cent, the product on broken land 12.14, and the product on summer fallow 11.7S. 



The nitrogen content of sound and frosted wheat was studied and the results 

 are given in tables. In 3 samples of sound wheat of as many different varieties 

 tlie total nitrogen ranged from 2.29 to 2.GS per cent, and the percentage of total 

 nitrogen in the form of albuminoid nitrogen from 94.1 to 9G.5. Four varieties 

 of frosted wheat ranged in total nitrogen from 1.S7 to 2.47 per cent and the 

 percentage of albuminoid nitrogen from 90.7 to 9G.7. Four varieties of badly 

 frosted wheats gave a total nitrogen content varying from 2.12 to 2.59 per cent 

 and the percentage of total nitrogen in the form of albuminoid nitrogen from 

 83.9 to 90.1. Apparently these results show that in frosted wheat the proportion 

 of nonallnnninoid nitrogen compounds is somewhat larger than in fully ripened 

 grain. It is pointed out that tlie nonalbuminoid nitrogen compounds are of less 

 nutritive value than gluten, and that hence frosted wheat is inferior to the 

 mature grain although they may have the same total nitrogen content. 



It was found that flour from both sound and frosted wheat contains a larger 

 proportion of its nitrogen in the true albuminoid form than does the wheat 

 from which it is made. It is stated that the proportion of total nitrogen in the 

 form of albumin<nd nitrogen is apparently as large in the flours from frosted as 

 from sound wheals, and" this is considered due to the removal in milling of the 

 embryo and bran which are high in nonalbuminoid coni])ounds. 



The tabulateil results of potato analyses show the dry matter, ash, and nitro- 

 gen content at the time of harvesting, and after several nionllis of storage.
