84(3 EXPERIMENT STATION EECORD. 



varieties of potatoes were grown on liglit marsti soil poor in lime. 

 Four plats were used in each test. Plat 1 was used as a check. The 

 others received marl, loamy marl, and quicklime, respectivelv. Marl 

 was used at the rate of 112 cwt. per hectare and quicklime at the rate 

 of 51 cwt. per hectare. One of the varieties of potatoes grown, the 

 Hamburger Egg potato, proved too tender for successful growth in 

 the fresh marsh soil, and its culture resulted in decreased yields and 

 linancial loss except where ground marl was used. With the other 

 variety of potato, the Bruce, increased j^elds were obtained with all 

 the different forms of lime, but the greatest net profit with this variety, 

 $68.58 per hectare, was obtained on the plat given the ground marl. 

 A table showing the amount of marl to apply on land when the marl 

 contains different amounts of calcium car])onate is given. 



Experiments in the culture of the sugar beet in Nebraska, H. H. 

 NiciiOLSOX and T. L. Lyon {Xehraal-a Sta. Bid. 07, pp. 17-21, jigs. 

 2). — This bulletin summarizes the results secured during the season in 

 cultural, fertilizer, and variety tests with sugar beets. As in previous 

 trials (E. S. R., 11, p. 839), the experiments have been carried out on 

 a large scale on the Standard Cattle Company's beet sugar fields at 

 Ames, in the Platte River Valley. 



Heav}^ cla}' soils have produced better beets both in years of average 

 and of excessive rainfall than sandy loam soils, though they did not 

 mature so rapidly. In selecting land for sugar beets the authors 

 advise choosing a clay soil. Shallow cultivation 3 to 1 in. deep through- 

 out the season, with the rows 18 in. apart and the plants 8 in. distant in 

 the row, has again given the most satisfactorj^ results. " A plan that 

 gave very satisfactory results was to allow 18 in. between everj- fourth 

 row and 15 in. between the others. This plan admits of horse cultiva- 

 tion if a four-row seeder and cultivator are used." 



The author states that — 



"Of the varieties tested during 1898 and 1899, on Ixjth heavy and Ught soil, the 

 best were the original Kleinwanzlebener, Pioneer Kleinwanzlebener, Yihnorin, 

 Drumez Elite, and Knauer. * * * The use of commercial fertilizers and of barn- 

 yard manure increased materially the yield per acre, but not the sugar content or 

 purity of the beets. The advantage to be derived from the use of commercial ferti- 

 lizers is not sufficient to pay for their cost. With barnyard manure, however, the 

 case is entirely different, and its use either for a previous crop or directly for the beet 

 crop is very profitable. ' '

{Oklakoiiui St<i. Bui. J^7,pj>. 26-4S). — Experiments are recorded con- 

 sisting of early, medium, and late plowing; early, medium, and late 

 seeding; growing wheat continuousl}' on the same soil with and with- 

 out manure, and tests of varieties. 



In the tirst experiment, ground from which a crop of oats had l:»een 

 harvested was divided and sections plowed July 1!», August 15, and 

 September 11, respectively. The section plowed July 19 turned up
