176 GROWING ANNUAL LEGUMES
or other mill feeds. What percentage is lost in one case or gained in
the other?
3. Charts of annual legumes may include a list of winter annuals
and the use of each; a list of summer annuals and the use of each; rates
of seeding alone and in mixtures; a peanut chart may list the costs in
production and in yields.
4. Debates.— Peanuts vs. beans for profit,” “ Cowpeas vs. Soybeans,”
“ Mixtures with grains and grasses vs. sowing alone,” “ Vetches vs. other
annual legumes,” © Lespedeza vs. Bermuda.”
5. Field Trips.—Visit a peanut oil and butter factory. Visit a bean
or pea cannery. Study field operations on farms of the best managers.
Practise in fields as many of the operations with these legumes as possible.
6. Projects.—Good student projects may be planned in growing field
beans, peas for canneries, peanuts, and in hay crops of other annual
legumes. Begin with the fall operations and continue all steps until the
following fall.
7. Trials with Projects.—Test the value of inoculation; of commer-
~ial fertilizers or lime; of different varieties and of different soil treatments.
8. Exercises.— (1) Collect seeds of all of these legumes for identifica-
tion and comparison. (2) If possible, secure fresh nodule specimens
for study. (Fig. 38.) (3) Collect the largest plants of each and mount
them on botany sheets for permanent reference. (4) Make germination
tests of large and small seeds to determine effects of different depths of
planting. (5) Demonstrate that when soybeans are planted too deep they
“ break their necks” in sprouting.
