 AZ Master Gardener Manual: Roots
The structure and growth habits of roots have a pronounced effect on the size and vigor of the plant, method of propagation, adaptation to certain soil types, and response to cultural practices and irrigation.
The principal functions of roots are to absorb nutrients and moisture, to anchor the plant in the soil, to furnish physical support for the stem, and to serve as food storage organs.
The depth and spread of the roots is dependent on the inherent growth characteristics of the plant and the texture and structure of the soil.

Tuberous sclerosis is a group of two genetic disorders characterized by problems with the skin, brain/nervous system, and kidneys.

The symptoms of tuberous sclerosis vary considerably: from minimally affected people with normal intelligence and no seizures, to severely affected people with profound retardation and frequent, difficult-to-control seizures or serious tumors.

The tuber, which is an underground stem that stores food, differs from the true bulb or corm in that it has no covering of dry leaves and no basal plant from which the roots grow.
Tuberous roots are the only ones from this group that are real roots; their food supply is kept in root tissue, not in stem or leaf tissue as in other bulbs.
Rhizomes, tubers, and tuberous roots are more easily desiccated than bulbs and corms, and should be stored in peat, perlite, or vermiculite.

 Paper 7: Agronomic aspects of root and tuber crops important for estimating production: cassava and sweet potato in ...
Known fresh tuberous root yield from real farms (survey) over a wide area and for different conditions will produce a data bank of real yields against which other data can be cross-referenced and checked before being used in the development of the overall estimate of crop production; 5.
(1980) noted that exceptional cassava fresh root yields of over 80 t/ha/year occur but that under favourable growing conditions, around 18t/ha of dry roots or 30 t/ha of fresh roots are obtained in 12 months of growth, and that higher yields are seldom attained in practical farming.
Assume we use this general mean as estimate of the yields of all varieties in an area for which the cumulative hectares is known, we would not be far from a good estimate of the output from the farms in that area.

 PACSOA - Zamia pumila
It also forms a large tuberous root, which is an extension of the above-ground stem.
The tuberous root expands into an ever-larger mass as new stems arise, and there will normally be more root mass to the plant than exposed stem mass.
If for some reason the stem is forced to branch too soon (such as after destroying the terminal bud), there would probably not be enough root to sustain a normal looking top and the new multi-headed plant would turn out looking dwarfed, i.e.

 A review of ruminant responses to cassava-based diets   (Site not responding. Last check: 2007-10-21)
Data presented show: tubers and peel are good energy sources, which when well fortified with nitrogen, minerals, vitamins, and roughage, promoted positive and high performance levels in dairy and beef cattle, sheep, and goats: the foliage, which is rich in nitrogen.
Tubers may be peeled or unpeeled, washed (ash content), sun-dried or oven-dried while leaves may be analyzed fresh, or after writing, dehydration or fermentation.
A peculiarity of cassava tuberous root starch is the high amylopectin content (70%) making it a particularly suitable energy source for ruminants, particularly when combined with nonprotein nitrogen in feeds (Mailer 1977).
