It is one of the cheapest sources of starchPotato (Solanum Tuberosum) occupies a prominent position in the world's food economy. As a fresh vegetable, potatoes are consumed in a variety of ways - boiled, steamed, curried, baked or roasted. They are also processed into many products such as chips, flour, French fries and canned.Solanum tuberosum is a herbacecious perennial. The aerial part of the stem is erect in the early stages of growth, but later spreads around. Except for the nodes the aerial stem is hollow. The underground portion of the stem is more or less rounded and solid; sending forth horizontal branches. The first few leaves developing from the stem piece are usually simple but subsequent ones are compound and pinnate. The leaves are 3-6 cm long, each consisting of one terminal leaflet, two to four pairs of large lateral primary oval leaflets with serrate margins. The tuber is the short, generally enlarged portion of the stolon — full of stored food, bearing `eyes' in the axils with smooth skin yellow in colour.

Potato can be grown in pots - by cutting pieces with the `eyes' and planting them in loose humus with compost and sand.
