BARLEY IIST THE GREAT PLAINS AREA. 25 



The results range from an average yield of 8.9 bushels per acre 

 on spring-plowed barley land to 19.3 bushels per acre on summer- 

 tilled land. Green manure is in second place, with average yields 

 of 15.5 bushels per acre. In all but the first year, peas plowed 

 under produced slightly larger crops than winter rye similarly 

 treated. There has been a gain of 1 bushel per acre from sub- 

 soiling over fall plowing not subsoiled. Furrowing over winter 

 with a lister produced practically the same as fall plowing. Fall- 

 plowed barley stubble gave better results than spring-plowed bar- 

 ley stubble. Spring-plowed oat stubble produced practically the 

 same as fall-plowed barley stubble. Disked corn ground produced 

 slightly better yields than the average of the crops following small 

 grains on fall or spring plowing. 



The main positive result shown in the table of yields is an increase 

 of about 6 bushels an acre as the result of summer tillage, or a some- 

 what lesser increase as a result of modifying the summer tillage by 

 plowing under a crop of green manure. 



The only method that produced barley at a profit was that of 

 disking corn ground. This shows a profit of $1.13 per acre. All 

 other methods show losses which range from 24 cents on listed 

 ground to $3.49 on summer-tilled land and $8.15 on green-manured 

 land. 



GARDEN CITY FIELD STATION. 



During the work of six years with barley under study at Garden City, 

 Kans., one crop has been lost by drought and one by hail. In the 

 other four years, yields have been obtained. 



The highest average yield, 11 bushels per acre, has been obtained 

 from summer tillage. Next to this in point of average yield is disked 

 corn ground. Subsoiling has given the same average yields as fall 

 plowing done at the same time without subsoiling. Marked advan- 

 tage in two years appears to have been derived from furrowing with 

 a lister and leaving the land rough through the winter instead of 

 plowing. 



On the whole the average yields are so low and there are so many 

 inconsistencies in the behavior of the different methods from year to 

 year that the results are chiefly valuable as indicators rather than as 

 definite guides to practice. It appears that there is sound reason for 

 the consensus of opinion as evidenced by farm practice which gives 

 little place to spring-sown barley in the territory served by this 

 station. 



The crop has been produced at a loss by all the methods under 

 trial. The losses range from $1 per acre on disked corn ground to 

 $6.89 on summer-tilled land.
