Demoor found only 3.6°/o of albuminoids, but the hay he analysed was over-ripe. 
From these analyses, it is clear that the nutritive value is nearly equal to that of hay of 
medium quality.

It is not customary to sow 
easily harvested. The bulk of commercial seed is 
often nothing else than the cleanings from tall oat 
grass (Avena elatior). These cleanings are very 
impure and are very frequently sold as the seed of up- 
right brome. When such seed is sown, no brome ap- 
pears for the first two years, although this grass was 
the main constituent of the mixture. The reason is clear. 
Avena elatior developes much more rapidly than the 
brome and, accordingly, forms the bulk of the produce. 
Only after the second year, when the tall oat grass is 
losing its vigour can upright brome gain the upper hand. 
The seeds of false brome, Brachypodium pinnatum, 
(fig. 47) are often labelled Bromus erectus. They are 
easily recognised by their straw colour and by the inner 
pale which is shorter than the outer, blunt at the apex, 
and comb-like on the margin. Rough brome, Bromus 
asper (fig. 48), a hard wood grass, is sometimes sub- 
stituted. The seed of this brome is recognised by the 
abundant hair on the outer pale; upright brome has no 
hair there. 
Seed and amounts to be sown. The average purity 
is 80°%o and the germination 64° = 51.2% of pure 
and germinating seed. On an average, one lb. of pure 
seed contains 114,000 seeds. A bushel weighs from 
14*/2 to 15 lbs. 50 lbs. of seed are required per acre Amount to be
