"At high altitudes alfalfa requires careful treatment to secure a good stand and 

 become well etJtaljlished. Heavy seeding and planting with the press drill ai'e rec- 

 ommended. 



"Two seasons are required to put the alfalfa into good i)roducing coiiditinn on the 

 Laramie Plains. . . . 



"Alfalfa will not grow on wet land where tlie ground water stands as near the sur- 

 face as 1 or 2 ft. . . . 



" Alfalfa grows better wliere there is some alkali salt in tlie soil, but will not stand 

 more than 1 per cent of our common white alkah in the first 6 in. of soil. It should 

 not 1)0 planted where there is enough alkali to form wliite incrustations ou the surface 

 of tlie soil during any part of the year." 



Corn culture, C. W. Burkett {Heui TTampshire Sta. Bid. 71, pp. 

 Jf.7-''>8.,Jigs. 3). — Methods of culture, effect of witch grass in growing 

 corn, and depth of plowing in reference to corn production wei-<^ the 

 problems investigated in this experiment. 



Meihoih of CKlt/rathig corn (pp. 47-53). — Certain corn plats weve 

 given no cultivation, others 5, and others 14 cultivations. Some of 

 the plats were cultivated deep and others shallow. The results ob- 

 tained in each case are tabulated and disctissed, and a summary given 

 of deep V. shallow cultivation experiments with corn at 17 experi- 

 ment stations. On the plats not cultivated the weeds grew luxuriantly 

 and the jdeld was redticed to 17.1 bu. of shelled corn per acre. The 

 plats cultivated shallow 14 times yielded at the rate of 80.6 bu. of 

 shelled corn per acre; cultivated 5 times shallow, the yield was 79.1 

 bu. ; and cultivated 5 times deep, 69.7 bu. per acre. The amount of 

 stover produced in each instance stood in aljout the same ratio as the 

 grain proditction. The plat which had received a mulch averaging 

 3 in. in thickness of old swamp hay and given no further attention 

 during the remainder of the season, yielded at the rate of 56.1 bu. 

 of shelled corn per acre. The mulch was not sufficient to keep all of 

 the weeds down. In the author's summary of the results of deep 

 and shallow cultivation experiments carried on at other stations it is 

 shown that out of 56 tests 36 were in favor of shallow culture, 12 in 

 favor of deep culture, and 8 were inconclusive. 



Effect of witch grass on corn production (pp. 53-55). — In this experi- 

 ment witch grass was allowed to grow in the drilled rows of corn on 

 certain plats which were cultivated but one way. Other plats were 

 similarly cultivated except that the witch grass was removed from 

 between the hills with a hand hoe. The yield of the hoed corn was at 

 the rate of 81.6 Ini. per acre, and of the unhoed 61.4 bu. per acre. In 

 this experiment the increased yield of both stover and grain ]):ii(l many 

 times over for the c^xtra labor of hoeing. 



Iffeci (f dcpiJi (f j>loiinng on yield <f corn (pp. 56-58). — Plats of 

 corn land were plowed in the fall 3, 5, 7, and 9 in. deep, respectivel}'. 

 The plats were similarly prepared in the spring and planted to Leam- 

 insr corn. No differcMice was seen in the growth of the corn on the 

 different plats until about the middle of the season when the deeper-
