lowed and by virtue of the summer rains a yield of 133 pounds per 

 acre was obtained. 



Sonora wheat planted in December occupied the third field and 

 the indifferent crop, yielding 290 pounds of grain per acre, was 

 plowed under for green manuring purposes. Following the wheat, 

 Tepary beans were planted and 121 pounds of recleaned beans per 

 acre were obtained. 



On the fourth field both Dwarf Kafir and Club-top sorghum 

 \.ere planted in March. A fair stand was obtained and replanting 

 1 uide considerable improvement. The drought resistant quality of 

 Dwarf Kafir was quite manifest and the season's work resulted in 

 7350 pounds of green fodder per acre. Very little Club-top came up 

 and that which did emerge was greatly damaged by drought. It 

 yielded 2600 pounds of green fodder per acre. 



UNIVERSITY FARM 



Demonstration work rather than experimental work was con- 

 ducted by the Department of Agronomy on the University Farm, 

 located four miles north of the campus. The land was used chiefly 

 in the production of feed for the livestock at present thereon. About 

 forty acres are under cultivation, twenty-five of which are in alfalfa 

 and the remainder in annual crops. 



alfalfa 



Considerable of the alfalfa has been seeded for a number of 

 years and the stand is no longer satisfactory. Various weeds are 

 appearing in great numbers and the alfalfa growth is not at its 

 maximum. The yield of hay from this part of the farm w^as ap- 

 proximately four tons per acre. 



grains 



Nearly fifteen acres of the, land devoted to annual crops were 

 planted to barley in November, 1916. Seven acres of this, on a 

 field which wrs first put in cultivation in June of last year, was 

 plowed under for green manuring purposes, the growth being in- 

 sufficient to justify its harvesting. The remainder yielded approxi- 

 mately one ton of hay per acre.
