FIELD CROPS, 229 



mang-el-wurzels; variety tests with uiillct, grasses, clovers, buckwheat, 

 spring wheat, spring rye, barley, oats, field peas, field beans, Japanese 

 beans, carrots, mangel-wurzels, sugar beets, and Swedish and fall 

 turnips; tests in growing grass, peas, and 2 varieties of vetches for 

 green fodder, 3 mixtures of grain for green fodder, 6 varieties of corn 

 for grain fodder or silage; sowing peas at dift'erent dates to deter- 

 mine the amount of injurj' done by the pea weevil; planting potatoes 

 the same day and 5 da3^s after being cut; and planting corn in rows 

 and in squares. 



In the experiment in planting peas at dift'erent dates it was found 

 that the percentage of weevily peas as well as the total yield deci'eased 

 as the date of seeding advanced, the 5deld of peas sown on June 6 

 being only about one-third as great as from peas sown on April 30. 

 Planting seed potatoes immediately after the}^ were cut yielded on the 

 average 12 bu. more per acre than was obtained from seed planted 5 

 days after being cut. Corn grown in squares gave a larger yield than 

 when planted in drills, the experimenters deciding in the proportion 

 of 14.1 in favor of planting by this method. 



Report of the Arkansas Valley Substation, H. H. Griffix 

 {Colorado Sta. Rpt. 1899^ pj^. 55-70^ fig. 1). — A report on the culture 

 and 3'ield of wheat, corn, alfalfa, plants for green manuring, pasture 

 and forage, cantaloupes, potatoes, celery, sugar beets, beans, and cer- 

 tain orchard and small fruits. In some cases results of irrigation 

 experiments are included. The results of a feeding test are noted 

 elsewhere in this issue (p. 275). 



Three irrigations proved as effective as 7 for cantaloupes. The 

 yields in both cases were larger than where only one irrigation was 

 given, but the quality of the cantaloupes was more satisfactory with 

 the one irrigation. Cantaloupes grown on alfalfa sod gave better 

 jields and fruit of better quality than when grown on other soils and 

 fertilized with barnj^ard manure or bone dust. Transplanting vines 

 started in the greenhouse gave a larger proportion of early fruits than 

 was obtained when the seeds were grown in hills in the open field. 



Paris green was used effectively as a remedy against the black flea- 

 beetle, and Bordeaux mixture against the leaf blight of cantaloupes. 

 The percentage of sugar in the juice of the sugar beets grown varied 

 from 13.8 to 16.9, and the purity from 80 to 86.8. Some data are 

 given on the cost of growing sugar beets, but they are not reduced to 

 any common unit of comparison. 



Field experiments, E. K. Lloyd {Jfississippl Sta. Rpt. 1899., fp. 

 9-13). — Variety tests with cotton and wheat, fertilizer tests with cot- 

 ton, and culture experiments with hairy vetch ( Yicia villosa) are 

 briefl}' reported. 



The heaviest yields of the 20 varieties of cotton grown were afforded 

 by Hawkins Jumbo and Texas Bur, each producing over 700 lbs. of
