to establish a uniform, thin stand, which is essential to securing the 
stocky growth that is neccessary for good seed production. Growing 
alfalfa in rows with intertillage, induces more surface branching of 
the roots, which is desirable in dry land conditions, or where it is desir¬ 
able to regulate the growth with surface moisture. Plate No. 4, shows 
the relative growth of side roots in alfalfa flooded, and that grown 
in cultivated rows.

Objections to Alfalfa in Rozas .—The difficulties in handling 
hay machinery on the rough furrows is the principle objection urged 
against alfalfa in rows, but by running the mower with the rows, 
or diagonally across the rows, this objection can be overcome. There 
is also a tendency for the loose soil in rowed alfalfa to wash out with 
heavy rains, but by selecting the proper field and running the rows on 
a slower grade, this difficulty can be obviated. If alfalfa in wide 
rows is left neglected it will become a veritable weed patch. 
JDistance Between Rows .—The proper distance to seed alfalfa in 
rows for seed production has not been fully established. In fact there 
will probably be no set rule, as the distance will vary according to the 
location, the supply of moisture, and the nature of the soil.
