7. Stubble of wheat or leguminous crops.
8. Comp. (1) Brush-crop, (2) Brush-wheat, a crop sown on
stubble, directly after a similar crop.
(1) Hrf. If this brush crop produces somewhat more than half
the quantity yielded by the fallow, the grower is satisfied, Marshall
Review (1818) II. 324. (2) Chs. He is also restrained from sowing
brush-wheat, MARSHALL Review II. 19; Chs.1 The sowing of two white or corn
crops in succession is prohibited in most farm agreements. It was
customary for the outgoing tenant to take two-thirds of the crop
if the wheat were grown after a bare fallow; one-half if after any
kind of green crop; but if it were brush wheat only one-third.
Frequently the outgoing tenant would stick a small branch of hazel
or other bush on the top of every other stook, then they each
knew which were their own. s.Chs.1
