1150 EXPERIMENT STATION RECORD. 



In 3 samples of yellow corn with white-tipped grains scattered about over the 

 ears, possibly due to cross fertilization, there was no material difference in the per- 

 centage of nitrogen of the white tipped and the yellow grains. The author concludes 

 that this indicates that there is no change in the nitrogen content from the first 

 year's cross fertilization. Longitudinal rows of grains on opposite sides of the ears 

 gave approximately the same percentage of nitrogen. 



Experiments with corn, C. G. Williams (Ohio 8ta. Circ. 53, pp. 11, dgms. 2). — 

 The tabulated results of varieties of corn tested for 3 years show that many of them 

 are not adapted to Ohio conditions. Experiments in thick and thin seeding pointed 

 out that the increase in yield was very pronounced up to an average stand of 3.62 

 plants per hill, the rows being 42 in. apart each way, but that it was accompanied 

 by a decline in average weight per ear, which was especially marked when more 

 than 3 plants were grown per hill. 



From field counts made in 63 counties by 328 correspondents it was estimated that 

 the stand of corn in the State for 1905 was 83.6 per cent, The method of conduct- 

 ing an ear-row test plat is described in detail and the total yields of each row of a 

 duplicate test of this kind is shown in a diagram. The yields from the different 

 ears varied from 50 to 115 bu. per acre. Notes are given on a score card for dent 

 corn and on the selection of seed ears. 



Cooperative fertilizer experiments with cotton in 1901, 1902, 1903, and 

 1904, J. F. Duggar (Alabama College Sta, Bui. 131, pp. 17-74).— in these coopera- 

 tive experiments the station furnished material and instruction to farmers upon the 

 agreement that the tests be made. The first year 10 reports were received, the sec- 

 ond 13, the>third 10, and the fourth 21. The conclusions and suggestions are based 

 on these experiments and on earlier work. 



The use of acid phosphate was found almost universally beneficial. Kainit, which 

 was less frequently of benefit than acid phosphate, gave its best results where the 

 crop was attacked by black rust. One hundred pounds of this substance per acre 

 was usually found sufficient. The results indicated that on soils containing much 

 clay kainit was unprofitable. 



Cotton-seed meal proved to be very effective on all soils except on new land, or on 

 soil rich in vegetable matter. For old lands a mixture of acid phosphate and cotton- 

 seed meal, or of these two substances and kainit,. is recommended. A small growth 

 of stalks under favorable conditions of climate and culture is regarded as showing a 

 deficiency of nitrogen in the soil, and a rank growth as indicating that only a small 

 quantity or no nitrogen at all need be applied. The use of phosphates hastened 

 maturity and the freshness of the land reduced the need for nitrogen. After a lux- 

 uriant growth of cowpeas or a recent heavy dressing with stable manure or cotton 

 seed, applications of cotton-seed meal were superfluous. Fertilizer formulas for the 

 cotton crop on various kinds of soils in different parts ot Alabama are suggested. 



The great millet or sorghum in Madras, 0. Benson and C. K. Subba Rao 

 (Dept. Agr. Madras Bui. 55, pp. 122). — This bulletin gives a popular description of 

 the crop and of the methods of its culture in Madras. 



Four-year culture tests with oats, 1901-1904, YV. Edler (Arh. Deut. Landw. 

 Geseli, 1906, No. 114, pp. 370).— The individual tests of cooperative experiments for 

 the different years are described and notes are given on the 13 varieties compared. 

 Strube oats gave in general the highest yields of grain, and especially good returns 

 were secured under favorable moisture conditions. 



In dry seasons Leutewitz Yellow ranked first in yield of grain, but in seasons with 

 a greater moisture supply several varieties gave better yields. Beseler II succeeded 

 only with a good supply of soil moisture, while Beseler 111 gave average results for 

 the different years as compared with all the varieties tested. Duppau, Heine Pro- 

 lific, Heine Trauben, and Anderbeck gave medium yields and were apparently not 

 very readily influenced by weather conditions. Probstei and Fichtelgebirg pro- 

 duced medium yields under unfavorable conditions, but otherwise they were out-
