was very little difference in yield of the plots planted at 3.5, 5.2
and 7.0 pounds of seed per acre, as given in Table 3. There was,
however, a decidedly higher yield on those plots which had been
sown at the rate of 10.5 pounds of seed per acre.
 The plots sown at the rate of 3.5 pounds per acre produced
plants with slightly coarser stems, and the leaves did not fall as
badly as on those sown more thickly. The plots sown at the rate
of 60 seeds per foot, or 10.5 pounds per acre, produced higher
yields of forage, and plants of smaller stems than plots with
lower seeding rates and allowed much less weed and grass
growth. The lower leaves, an important source of feed, had
turned yellow and dropped before time of harvest. The plots
seeded at the rate of 5.2 to 7.0 pounds per acre, while producing
slightly coarser stems, grew a product which held an abundant
leafage and therefore made a better quality feed than did those
sown at a heavier rate. The seeding of Crotalaria intermedia in
rows 3 feet apart at the rate of 5.2 to 7.0 pounds per acre may be
expected to produce the maximum yield of a high quality for-
age.
 Broadcast.-A series of plots were seeded at 3 rates to
Crotalaria intermedia on April 6. The field was disked thoroughly,
the seed sown broadcast and covered with a spike-tooth harrow.
 The crop was harvested on August 31. at which time the
plants were in the advanced bud stage. They were, therefore, a
few days further advanced than the crop harvested from the
drilled areas.
 The plots seeded at the rate of 8 pounds per acre produced
the highest yields, as shown in Table 4. The lowest yields were
obtained from the plots seeded at the rate of 4 pounds per acre.
The seeding of 12 pounds per acre produced a slightly lower
yield than did seedings at the rate of 8 pounds; the difference
