... Mixing tarwi and cereals makes a food that, in its balance of amino acids, is almost ideal for humans. With its outstanding composition, tarwi might become another "soybean" in importance.2 Because of this possibility, researchers in countries as far-flung as Peru, Chile, Mexico, England, the Soviet Union, Poland, East and West Germany, South Africa, and Australia have initiated tarwi research.

... However, the sweet types could make the plant into a major crop for tropical highlands and for a number of temperate regions. So far it is barely known outside of South America, but a hopeful sign is that in Chapingo, Mexico, tarwi has produced high yields of seed.4 3 These pilot plants are capable of processing 7,000 tons of seed per year into vegetable oil and plant protein.
From page 183...
... Current types mature late in temperate latitudes, but a diligent search of the native germplasm in the Andes will likely turn up quick-maturing forms. USES As has been mentioned, tarwi appears to be a ready source of vegetable protein and vegetable oil for both humans and animals.

... .6 Removing the seed coat and grinding the remaining kernel yields a flour that contains more than 50 percent protein. Tarwi protein has adequate amounts of the essential amino acids lysine and cystine, but has only 25-30 percent of the methionine required to support optimal growth in animals.

... ~ ~ Many forms of the plant resist the lupinosis fungus, which sometimes kills livestock that feed on the foliage of other lupin species. Also, many ecotypes are resistant to lupin mildews and rots.~3 HARVESTING AND HANDLING Unlike many lupin species, tarwi pods do not split and shed their seed on the ground.
From page 187...
... The challenge now is to make them stable, so that the low alkaloid content is inherited uniformly by succeeding generations. Also, the initial low-alkaloid strains have been proven highly susceptible to insect attack.
From page 188...
... (Such determinate types have been located in southern Peru and Bolivia and probably can also be found elsewhere in the Andes. Synchronous ripening would be particularly useful in many locations dependent on mechanical harvesting.

... . Nonbitter types with soft seed coats were discovered in Germany in the 1920s.
