iua<;hinery used in seeding. It is believed that this will obviate the necessity 

 of waiting for rain before seeding, thus permitting early seeding, which seems 

 desirable, and allowing the crop time enough to make a fair growth before 

 the advent of winter. Late planting is often followed by much winterkilling, 

 which completely offsets the value of any tillage method used in preparing the 

 land and of the quantity of moisture stored in it. 



" The average result of five years' tests shows no difference in the yields 

 of winter wheat seeded at different depths. The yields were greatly influenced 

 by conditions at seeding time. The ordinai'y drilling of winter wheat has 

 given more profitable yields than bi'oadcasting or cross-drilling. 



" The results of three years' experiments show that winter wheat sown at 

 the rate of 4 to 5 pk. per acre is more profitable! than when sown at 3 pk. per 

 acre, the rate ordinarily used on the dry lands of the Great Basin. 



" The average yields of five years favor no spring cultivation of winter wheat. 

 The noncultivated plats yielded 17.05 bu., as compared with 15.09 bu. from 

 those cultivated. There was no apparent difference in the moisture content 

 of the plats. A test made in the spring of 1913 showed that 11.54 per cent 

 of the plants were killed by one harrowing. This loss offsets all benefits that 

 might have come from harrowing. 



" The results of four years favor harvesting when the grain is in the hard- 

 dough stage. 



" Where a good stand was obtained and little winterkilling followed, winter 

 wheat after fallow yielded more than winter wheat on continuously cropped 

 land. This depended largely upon the season, however, and the continuously 

 cropped plat, owing to volunteer grain, yielded as well or better than other 

 plats in the test in seasons of much winterkilling. 



"The average acre yield of winter wheat for five years was less after fallow 

 than after corn, potatoes, or peas." 



[Field crop experiments], A. M. McOmie (Arizon-a Sta. Rpt. 1013, pp. 243- 

 250, fig. 1). — This reports work at the dry fai'ms and the central station for 

 1913. At the Prescott dry farm Moqui Indian corn is noted as being inferior 

 to Kafir com in jaeld, and fallowed land proved more productive than that 

 continuously cropped. Feterita, white milo maize, kaoliang, Sudan grass, 

 durra, Canada field peas, tepary beans, and Grimm and Turkestan alfalfa 

 are noted as being new introductions. Cultural trials with many varieties 

 of spring and winter wheat, oats, barley, rye, spelt, emmer. and millet are 

 noted. Turkey lied wheat planted about August 20 is tlie only winter cereal, 

 it is stated, to mature at the experimental dry farms. It yielded from 10 to 12 

 bu. per acre. At Phoenix cultural trials of wheat, barley, oats, spelt, corn, 

 sugar beets, sugar cane, grain sorghums, forage sorghums, shallu, potatoes, 

 and tepary beans are noted. 



Beport of the work done at Holly Springs branch, experiment station, 

 1913, C. T. Ames (mssissippi Sta. Bill. 165 {1914), pp. 13-21, 26, 32, figs. 4).— 

 Tests with 26 varieties of corn gave yields that ranged from 30.5 to 57.8 bu. 

 per acre ; 28 varieties of cotton yielded from 352 to 671 lbs. per acre of lint 

 cotton, or from 1.169 lbs. to 1.843 lbs. of seed cotton. Length of staple ranged 

 from ^ to 1t^ inches. Fertilizer tests indicated that the soil was deficient in 

 both lime and phosphorus, as basic slag produced the best yields of lint cotton 

 in fertilizer tests. 



Some conclusions regarding the results of fertilizer tests with cotton covering 

 a period from 1906 to 1913, inclusive, are given as follows : 



" The use of both nitrogen and phosphorus, either alone or in combination, 

 has given very satisfactory results.
