cultivated with an ordinary corn cultivator, but narrow rows require 
some such tools as are used for sugar beets. Specific directions for 
the planting, cultivating, and harvesting of row plantings have been 
given under ‘‘ Hay production.”’ The method of planting and cultivat- 
ing the rows 1s the same whether they are intended for hay or for seed. 
The rate of planting in rows or close drills should be about the same as 
for hay, because the seed matures more uniformly in thick stands. 
The usual practice has been to sow rather thinly for seed production, 
but this has been warranted only by the scarcity and high price of seed.

1 These averages include only those stations where data are given for all three methods of seeding. 
Harvesting for seed is nearly always done with a row binder or a 
, grain binder rather than a mower. The grass when tied in bundles 
can be thrashed more efficiently and is easier to care for in the field. 
The shockers should follow closely after the binder, because the seed 
will become discolored if the bundles are allowed to lie on the ground
