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 growmg 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 well as the best method 

 of handling the same.
