SUMMARY. 35 
Bur clover seems to be of most value for deciduous orchard con- 
ditions, while the woolly-podded vetch promises to be of value for 
the same conditions. ; 
Fenugreek and bur clover are used to a limited extent, fenugreek 
being especially adapted to the region near the coast. 
Hairy vetch is not well adapted for use as a green-manure crop in 
California. 
Black bitter vetch, black-purple vetch, woolly-podded vetch, horse 
beans, and the Tangier pea are promising new green-manure crops 
in comparison with common vetch. 
Green-manure crops need no inoculation in California, horse beans 
in the northern portion being the only known exception. 
The growing of a summer green-manure crop in California orchards 
is not advisable. 
Local as well as sectional conditions in the various parts of the 
State vary considerably, and must be taken into consideration in 
determining the best crop for green manure as we ell as the best method 
of handling the same.
