A review of the literature shows conflicting opinion as to the 
value of sunflower as silage. The .suggestion* is made that the ash 
' 'would he a valuable fertilizer for certain soils. A table shows 
considerable variation in the analyses of sunflower products. The 
vitamin content of the oil hos been found to be low. Investigators 
have found that the oil dries slowly. 
Paragraphs are given on expressing the oil, on clarification, 
purification and bleaching, on the oil as a salad and frying oil, 
on its hydrogenation, and its use in paints.

best to harvest the sunflower crop for silage; (b) the best time 
( and rate of planting for silage; and (c) the -amount and kind of 
fertility removed in the crop,"
