There are only two species of cultivated rice in the world, Oryza sativa (Asian rice) and Oryza glaberrima (African rice). Both species are annual grasses (except in the tropics, where the plant can be perennial)

belonging to the family Poaceae which are cultivated for their grain which is considered a staple food in most parts of the world. Asian and African rice plants are morphologically very similar and can be difficult to

tell apart. They have rounded stems (called culms) which are divided into nodes and internodes. The plant leaves are borne on the nodes of the stem and are long and slender with a pronounced midrib. The plant

produces three flowers, two of which are reduced, on a spikelet on the terminal (last) internode of the stem. The rice grain is formed by the ripened ovary of the flower and is between 5 and 12 mm in length. Rice is

an annual plant, harvested after one growing season and can reach a height of between 1 and 1.8 m (3.3–5.9 ft) depending on variety. Generally, African rice tends to form smaller, pear shaped grains with a red

bran and olive to black seed coat and has several disadvantages compared with its Asian counterpart e.g. seed is easily scattered, the grain is difficult to mill and the crop gives a lower yield. The growing of Asian

rice has therefore begun to supercede that of African rice in West Africa. Asian rice originates from China and African rice is believed to have been domesticated in areas around the Niger river in Africa.

Rye, Secale cereale, is an herbaceous annual or biennial in the family Poaceae that is grown primarily for its grain. Rye has an erect slender stem topped with a curved spike which is 7–15 cm (3–6 in) length. The

head is made up of individual spikelets each with two florets which produce 1–2 kernels. The spikelets and arranged alternately along the length of the head.The leaves of the plant grow from nodes on the stem

and are lance-like blades, blue-green in color. Rye can reach 1–3 m (3.3–10 ft) in height and is either grown as an annual (spring rye) or biennial (winter rye). Modern rye does not occur naturally but is likely

derived from wild ancestors found in Afghanistan, Iran and the Middle East.

Squash is the collective name given to several species of plant in the genus Cucurbita, including C. maxima, C. mixta , C. moschata and C. pepo, which are widely grown for their edible fruit. Squash plants are are

herbaceous annual plants which are either trailing vines or bush-like in morphology. Vines generally have large, lobed leaves and long vines which can climb by attaching to surfaces with their tendrils. Bushes

generally take up less space than the sprawling vine types and may have prickly leaves. Squash plants produce yellow or orange flowers and green, white or yellow fruit in a variety of shapes and sizes with

smooth or ridged skin. Vining squash varieties can reach several meters in length and, as annuals, survive only one growing season. Squash originate from North and Central America and are referred to by their

cultivar name e.g. acorn squash, butternut squash, spaghetti squash, zucchini, banana squash, hubbard squash and buttercup squash.

Soybean, Glycine max, is an herbaceous annual plant in the family Fabaceae grown for its edible seeds. The soybean plant is usually an erect bush with woody stems and alternately arranged leaves. The leaves

possess three individual leaflets which are oval or lance-like in shape, growing to a length of 3–10 cm (1.2–4.0 in). The soybean plant produces small white or purple flowers and curved seed pods which are 3–15

cm (1.2–6 in) in length and can contain between 1 and 5 seeds. The seeds can be a variety of colors including yellow, green, brown, black or a mottled combination. Soybean is an annual plant, surviving only one

growing season and can reach heights of 0.2–1.5 m (0.7–1.4 ft). Soybean may also be referred to as soyabean or soya and originates from Northeast China.
