Suppose after the silage had settled, a man had 24 feet of silage in 

 a silo 14 feet in diameter. By the table, he had 70 . 4 tons. Suppose 

 that on a given date his silage remaining indicated that he had 

 fed off 16 feet. This would mean that he had used 45 . 2 tons ac- 

 cording to the table. This amount subtracted from the original 

 weight would show 25 . 2 tons left in the silo. 



376. Sunflower silage. — The great popularity and proven 

 merit of silage rests largely on results secured from corn, and today 

 probably 90 per cent of the silage used is from the corn plant. 

 However, the remarkable results with corn have caused other 

 crops to be tried, particularly for conditions where the corn crop 

 cannot be depended upon. Many farmers and Experiment 

 Stations recently have been trying sunflowers for silage. Satis- 

 factory results have been obtained as regards yield and quality of 

 silage to give this crop a real place, at least in sections too cool and 

 too high in altitude for corn to thrive. 



377. Sorghum silage. — Silage made from the sorghums cut 

 at the proper stage of maturity ranks close to corn in value. The 

 sorghums are primarily grown in the Southwest, although certain 

 early varieties may be grown in the North. 



378. Silage from legumes.— The legumes make rather un- 

 certain silage when used alone because due to the higher protein 

 and less carbohydrate content the proper fermentation may not 

 take place. However, certain combinations of legumes and grains, 

 such as oats and peas, make excellent silage of higher protein
