Ian et al--
   Well I'll be a Leprachaun, dhaincha is indeed sesbania and 
not  crotalaria.  I'd say I was off base by at least a genus  :-) 
Thanks for posting the correct information.  

I've done some investigation for farmers looking at alternative 
green manures and fiber crops such as sesbania and crotalaria and 
also have several sources to offer on sesbania.  Both are more 
widely used in India than here in the U.S.  

Literature sources on sesbania:

Agricultural Studies No. 21.  Food and Agriculture Organization,
Rome.  p. 321-322.

of sesbanias for green manuring.  Tropical Agriculture

Economic Importance.  Plenum Press, New York.  p. 216-219.
Duke lists "danchi" as one of the common names for S. bispinosa,
and one of his references is titled "Composition of dhanchia

"In India, it is commonly called "dhaincha."


Dr. Robert Bugg at UC-Davis has done work with sesbania (and 
other cover crops) as insectary habitat for beneficial insects.

"Grown as a summer green manure, Sesbania (S. axaltata) often
harbors cowpea aphid and bandedwingend whitefly, and has proven
useful for retaining lady beetles when pecan aphids become

"May enhance biological control through providing alternate 
prey.  Harbored bandedwinged white fly and relatively high
densisites of cowpea aphid."

Shiitake mushroom production in the United States reached 2.7 million pounds 
in 1991-1992, says a fact sheet published by USDA Small-Scale Agricultural
Alternatives.  The United States imports 14,000 metric tons of dried Shiitakes
annually, nearly 100 times its current fresh production.
