When buckwheat is sown for seed, it should be in the last week of June.
it's produce is very precarious. Alexander reckons on about 10. bushels
to the acre on an average.
to make seed, it requires strong land
it is 10. weeks from the seed to it's harvest

when sowed for a green dressing, it should be thick, i.e. 3 pecks to
the acre. Alexander.
in 5. weeks it is fit for ploughing in.
it rots in the ground completely in a fortnight. G. Washington.
a dressing of buckwheat is equivalent to a coat of dung of about 10. loads
to the acre; calling the load a cubic yard, or ton-weight. Logan.
