36 EXPERIMENT STATION RECORD. [Vol.41 



Surcroppor and Strawberry com are recomiuendecl for uplands and the so- 

 called proline varieties for tlie bottom lands. Rate of seeding tests with corn 

 are held to indicate that the stalks should be thinned to 3 by 3 ft. In a com- 

 parison of corn grown alone with corn and cowpeas grown together, better re- 

 sults were secured the later the cowpeas were planted. 



The largest yields of cotton have been secured from hills spaced from 18 to 

 36 in. apart, containing two stalks per hill. Mebane, Ilowden, and Lone Star 

 are deemed to be the best varieties. 



Clay and New Era cowpeas are said to be suitable for general use, while 

 Chinese Red is recommended as a catch crop and Iron for forage. Wide row 

 planting has given more cowpea hay than narrow row planting, while heavy 

 seeding has given larger crops than light seeding. 



Soy beans do not appear to be profitable. 



Peanuts in 18-in. rows have not shown a profitable gain over 36-in. rows when 

 grown for nuts. Spanish peanuts are recommended for forage. In width of 

 row tests with this variety 36-in. rows produced more forage than 18-in. rows. 

 It was not found profitable to crack the shells of peanuts before planting. 



Sumac sorghum is recommended as a silage crop. Among new forage crops 

 tested each year, Kulthi moth bean. Florida beggar weed, Japanese sword bean, 

 and frijole bean are of little importance, while mung bean and Dolichos Uiblab 

 proved to be of some value. 



Sudan grass, newly introduced, is of considerable importance as an annual 

 hay and pasture crop. In date and rate of planting tests with Sudan grass the 

 results are held to indicate that rather late spring planting is necessary or that 

 early planting after oats is practical. It is advised that the crop be planted in 

 rows at from 5 to 15 lbs. of seed to the acre. 



Japanese sugar cane gives promise as a silage crop. 



The largest yield of tomatoes has been obtained from plats receiving 20 loads 

 of stable manure per acre. 



A study of environment in small grains, B. D. Halsted {New Jerseif Stas. 

 Rpt. 1911, pp. 394, S95). — This comprises a brief preliminary report on work 

 with wheat, oats, barley, and buckwheat, comprising a study of the influence of 

 the position of the grain on the plant upon the viability of the grain and the 

 vigor of the seedling, of the effect of the depth of planting upon the viability of 

 the seed and the weight of the plants pi-oduced, and the effect of the number of 

 plants per hill upon the weight of the plant. 



Seedings were made 1, 2, 3, 4, and 5 in. deep and the average weight of the 

 plants and the percentage of plants harvested at each depth ascertained. The 

 highest average weight per plant for wheat and oats was secured at the 5 in. 

 depth and amounted to 99.5 and 280 gm.. respectively, while the maximum 

 weight for barley, 144 gm., and for buckwheat, 68.1 gm., was secured at the 4 in. 

 level. The viability of wheat and oats increased from the 1 to the 3 in. depth 

 and then declined, while barley attained its maximum at the 1 in. depth, and 

 buckwheat at the 4 in. depth. 



Planting 1, 3, 5, 10, and 20 grains per hill resulted in maximum average 

 weights per plant of 85.3 gm. for wheat at the 5 grain rate, 410.6 gm. for oats 

 at the 1 grain rate, 140.3 gm. for barley at the 1 grain rate, and 98.8 gm. foi* 

 buckwheat at the 20 grain rate. 



Spring grains in western Nebraska, L. L. Zooic (Nebraska Sta. Bui. 112 

 (1919), pp. 16, figs. 4). — Experimental work is described in which observations 

 were made on the effects of different dates of seeding and on the relative yields 

 of spring grains, including wheat, oats, barley, and enuuer, at the North Platte 

 substation for the 10 years, 1909 to 1918, inclusive. A previous report on this 

 work has already been noted (E. S. R., 29, p. 225).
